THE BODY IS MADE UP OF INCREASING LARGER, AND MORE COMPLEX STRUCTURAL UNITS. FROM SMALLER TO LARGEST THESE ARE: CELLS, TISSUES, ORGANS, AND THE BODY SYSTEMS.

ARE THE BASIC STRUCTURAL AND FUNCTIONAL UNITS OF THE BOSY. CELLS ARE SPECIALIZED AND GROUPED TOGETHER TO FORM TISSUES AND ORGANS.

IS THE STUDY OF THE ANATOMY, PHYSIOLOGY, PATHOLOGY, AND CHEMISTRY OF THE CELL.

MEANS CELL

IS THE TISSUE THAT SURROUNDS AND PROTECTS THE CONTENTS OF THE CELL BE SEPARATING THEM FROM ITS EXTERNAL ENVIRONMENT.

IS THE MATERIAL WITHIN THE CELL MEMBRANE THAT IS "NOT" PART OF THE NUCLEUS.

MEANS FORMATIVE MATERIAL OF CELLS

IS SURROUNDED BY THE NUCLEAR MEMBRANE, IS A STRUCTURE WITHIN THE CELL THAT HAS TWO IMPORTANT FUNCTIONS: 1. IT CONTROLS THE ACTIVITIES OF THE CELL, AND 2. IT HELPS THE CELL DIVIDE.

STEM CELLS DIFFER FROM OTHER KINDS OF CELL IN THE BODY BECAUSE OF TWO CHARACTERISTICS:
1. STEM CELLS ARE UNSPECIALIZED CELLS THAT ARE ABLE TO RENEW THEMSELVES FOR LONG PERIODS OF TIME BY CELL DIVISION. THIS IS IN CONTRAST TO OTHER TYPES OF CELLS THAT HAVE A SPECIALIZED ROLE AND DIE AFTER A DETERMINED LIFESPAN.
2. UNDER CERTAIN CONDITIONS STEM CELLS CAN BE TRANSFORMED INTO CELLS WITH SPECIAL FUNCTIONS SUCH AS THE CELLS OF THE HEART MUSCLE THAT MAKE THE HEARTBEAT POSSIBLE OR THE SPECIALIZED CELLS OF THE PANCREAS THAT ARE CAPABLE OF PRODUCING INSULIN.

STEM CELLS POTENTIALLY HAVE MANY THERAPEUTIC USES, INCLUDING BEING TRANSPLANTED FROM ONE INDIVIDUAL TO ANOTHER. CELLS FOR THIS PURPOSE ARE HARVESTED FROM THE HEMOPOIETIC (BLOOD FORMING) TISSUE OF THE DONORS BONE MARROW. HOWEVER UNLESS THERE IS AN EXCELLENT MATCH BETWEEN THE DONOR AND RECIPIENT, THERE IS THE POSSIBILITY OF REJECTION KNOWN AS GRAFT VERSUS HOST DISEASE.

ALSO KNOWN AS SOMATIC STEM CELLS, ARE UNDIFFERENTIATED CELLS FOUND AMONG DIFFERENTIATED CELLS IN A TISSUE OR ORGAN. NORMALLY THE PRIMARY ROLE OF THESE CELLS IS TO MAINTAIN AND REPAR THE TISSUE IN WHICH THEY ARE FORMED.

MEANS NOT HAVING A SPECIALIZED FUNCTION OR STRUCTURE.

MEANS HAVE A SPECIALIZED FUNCTION OR STRUCTURE

ARE UNDIFFERENTIATED CELLS THAT ARE UNLIKE ANY SPECIFIC ADULT CELL; HOWEVER, THEY HAVE THE IMPORTANT ABILITY TO FORM ANY ADULT CELL.

1. THESE CELLS CAN PROLIFERATE (GROW RAPIDLY) INDEFINITELY IN A LABORATORY, AND COULD THEREFORE POTENTIALLY PROVIDE A SOURCE FOR ADULT MUSCLE, LIVER, BONE, OR BLOOD CELLS.
2. BECAUSE THESE CELLS ARE MORE PRIMITIVE THAN ADULT STEM CELLS, AN EMBRYONIC STEM CELL TRANSPLANT DOES NOT REQUIRE AS PERFECT A MATCH BETWEEN THE PATIENT AND DONOR AS THE TRANSPLANTATION OF ADULT STEM CELLS.

3. EMBRYONIC STEM CELLS COME FROM THE CORD BLOOD FOUND IN THE UMBILICAL CORD AND PLACENTA OF A NEWBORN INFANT. EMBRYONIC STEM CELLS FROM CORD BLOOD CAN BE HARVESTED AT THE TIME OF BIRTH WITHOUT DANGER TO MOTHER OR CHILD. THESE CELLS ARE KEPT FROZEN UNTIL NEEDED FOR TREATMENT PURPOSES.
4. EMBRYONIC STEM CELLS CAN ALSO BE OBTAINED FROM SURPLUS EMBRYOS PRODUCED BY IN VITRO (TEST TUBE) FERTILIZATION. WHICH THE INFORMED CONSENT OF THE DONOR COUPLE, STEM CELLS OBTAINED IN THIS MANNER ARE BEING USED FOR IMPORTANT MEDICAL AND SCIENTIFIC RESEARCH.

THE STUDY OF HOW GENES ARE TRANSFERRED FROM PARENTS TO THEIR CHILDREN AND THE ROLE OF GENES IN HEALTH AND DISEASE.

A FUNDAMENTAL PHYSICAL AND FUNCTIONAL UNIT OF HEREDITY. GENES CONTROL HEREDITARY DISORDERS AND ALL PHYSICAL TRAITS SUCH AS HAIR, SKIN, AND EYE COLOR.
GENE- MEANS PRODUCING

PERTAINING TO

A SPECIALIST IN THE GENENTIC FIELD

EACH NEWLY FORMED INDIVIDUAL RECEIVES TWO GENES OF EACH GENETIC TRAIT: ONE FROM THE FATHER AND ONE FROM THE MOTHER.

IS INHERITED FROM EITHER PARENT, THE OFFSPRING WILL INHERIT THAT GENETIC CONDITION OR CHARACTERISTIC.

WHEN THE SAME RECESSIVE GENE IS INHERITED FROM BOTH PARENTS, THE OFFSPRING WILL HAVE THAT CONDITION. FOR EXAMPLE, SICKLE CELL ANEMIA IS A GROUP OF INHERITED RED BLOOD CELL DISORDERS THAT ARE TRANSMITTED BY A RECESSIVE GENE. WHEN THIS GENE IS TRANSMITTED BY BOTH PARENTS THE CHILD WILL HAVE SICKLE CELL ANEMIA.

WHEN A RECESSIVE GENE IS INHERITED FROM ONLY ONE PARENT, AND A NORMAL GENE IS INHERITED FOR THE OTHER PARENT, THE OFFSPRING WILL NOT HAVE THE CONDITION. ALTHOUGH THE CHILD DOESN'T HAVE SICKLE CELL ANEMIA THEY WILL HAVE THE TRAIT AND CAN PASS IT TO THEIR CHILDREN.

A GENOME IS THE COMPLETE SET OF GENETIC INFORMATION OF AN INDIVIDUAL.

ARE THE GENETIC STRUCTURES LOCATED WITHIN THE NUCLEUS OF EACH CELL. THEY ARE MADE UP OF THE DNA MOLECULES CONTAINING THE BODY'S GENES. PACKAGING GENETIC INFORMATION INTO CHROMOSOMES HELPS A CELL KEEP A LARGE AMOUNT OF GENETIC INFORMATION NEAT, ORGANIZED, AND COMPACT. EACH CHROMOSOME CONTAINS ABOUT 100,000 GENES.

ANY CELL IN THE BODY EXCEPT GAMETES (SEX CELLS). THEY CONTAIN 46 CHROMOSOMES ARRANGED INTO 23 PAIRS. THERE ARE 22 IDENTICAL PAIRS OF CHROMOSOMES, PLUS ANOTHER PAIR. IN A FEMALE THIS PAIR CONSISTS OF XX CHROMOSOMES, AND IN A MALE THIS PAIR CONSISTS OF AN XY CHROMOSOMES. IT IS THIS CHROMOSOME PAIR THAT DETERMINES THE SEX OF THE INDIVIDUAL.

MEANS PERTAINING TO THE BODY IN GENERAL.

(SPERM OR EGG) ALSO KNOWN AS A GAMETE, IS THE ONLY TYPE OF CELL THAT DOES NOT CONTAIN 46 CHROMOSOMES. INSTEAD EACH OVUM (EGG) OR SPERM HAS 23 SINGLE CHROMOSOMES. IN A FEMALE, ONE WILL BE A X CHROMOSOME. IN A MALE ONE OF THESE WILL BE A X OR A Y CHROMOSOME. WHEN A SPERM AND OVUM JOIN, THE NEWLY FORMED OFFSPRING RECEIVES 23 CHROMOSOMES FROM EACH PARENT, FOR A TOTAL OF 46.

IT IS THE X OR Y CHROMOSOME FROM THE FATHER THAT DETERMINES THE GENDER OF THE CHILD. A DEFECT IN CHROMOSOMES CAN LEAD TO BIRTH DEFECTS. EXAMPLE, DOWN SYNDROME HAVE 47 INSTEAD OF THE USUAL 46.

DEOXYRIBONUCLEIC ACID. THE BASIC STRUCTURE OF THE DNA MOLECULE, WHICH IS LOCATED ON THE PAIRS OF CHROMOSOMES IN THE NUCLEUS OF EACH CELL, IS THE SAME FOR ALL LIVING ORGANISMS. HUMAN DNA CONTAINS THOUSANDS OF GENES THAT PROVIDE THE INFORMATION ESSENTIAL FOR HEREDITY, DETERMINING OUR PHYSICAL APPEARANCE, DISEASE RISKS, AND OTHER TRAITS

1. DNA IS PACKAGED IN A CHROMOSOME AS TWO SPIRALING STRANDS THAT TWIST TOGETHER TO FORM A DOUBLE HELIX. A HELIX IS A SHAPE TWISTED LIKE A SPIRAL STAIRCASE. A DOUBLE HELIX CONSISTS OF TWO OF THESE STRANDS TWISTED TOGETHER.
2. DNA IS FOUND IN THE NUCLEUS OF ALL TYPES OF CELLS EXCEPT RED BLOOD CELLS (ERYTHROCYTES). THE DIFFERENCE HERE IS DUE TO THE FACT THAT ERYTHROCYTES DO NOT HAVE A NUCLEUS.

3. THE DNA FOR EACH INDIVIDUAL IS DIFFERENT AND NO TWO DNA PATTERNS ARE EXACTLY THE SAME. THE ONLY EXCEPTION TO THIS RULE IS IDENTICAL TWINS, WHICH ARE FORMED FROM ONE FERTILIZED EGG THAT DIVIDES. ALTHOUGH THEIR DNA IS IDENTICAL, THESE TWINS DO DEVELOP FINGERPRINTS AND OTHER CHARACTERISTICS THAT MAKE EACH OTHER UNIQUE.
4. A VERY SMALL SAMPLE DNA, SUCH AS FROM HUMAN HAIR OR TISSUE CAN BE USED TO IDENTIFY INDIVIDUALS IN CRIMINAL INVESTIGATIONS, PATERNITY SUITS, OR GENEALOGY RESEARCH.

IS A CHANGE OF THE SEQUENCE OF A DNA MOLECULE. POTENTIAL CAUSES OF GENETIC MUTATION INCLUDE EXPOSURE TO RADIATION OR ENVIRONMENTAL POLLUTION.

IS A CHANGE WITHIN THE CELL OF THE BODY. THESE CHANGES AFFECT THE INDIVIDUAL BUT CANNOT BE TRANSMITTED TO THE NEXT GENERATION.

IS A CHANGE WITHIN THE GENES IN THE GAMETIC (SEX CELL) THAT CAN BE TRANSMITTED BY A PARENT TO HIS OR HER CHILDREN.

IS THE MANIPULATING OR SPLICING OF GENES FOR SCIENTIFIC OR MEDICAL PURPOSES. THE PRODUCTION OF HUMAN INSULIN FROM MODIFIED BACTERIA IS AN EXAMPLE OF ONE RESULT OF GENETIC ENGINEERING.

ALSO KNOWN AS A HEREDITARY DISORDER, IS A PATHOLOGICAL CONDITION CAUSED BY AN ABSENT OR DEFECTIVE GENE. SOME GENETIC DISORDERS ARE OBVIOUS AT BIRTH, OTHERS MAY MANIFEST (BECOME EVIDENT) AT ANY TIME IN LIFE.

A GENETIC DISORDER THAT IS PRESENT AT BIRTH AND AFFECTS BOTH THE RESPIRATORY AND DIGESTIVE SYSTEMS

A GROUP OF HEREDITARY BLEEDING DISORDERS IN WHICH A BLOOD-CLOTTING FACTOR IS MISSING. THIS BLOOD COAGULATION DISORDER IS CHARACTERIZED BY SPONTANEOUS HEMORRHAGES OR SEVERE BLEEDING FOLLOWING AN INJURY.

IS A GENETIC DISORDER THAT IS PASSED FROM PARENT TO CHILD. EACH CHILD OF A PARENT WITH THE GENE FOR HD HAS A 50/50 CHANCE OF INHERITING THIS DEFECTIVE GENE. THIS CONDITION CAUSES NERVE DEGENERATION WITH SYMPTOMS THAT MOST OFTEN APPEAR MIDLIFE. THIS DAMAGE EVENTUALLY RESULTS IN UNCONTROLLED MOVEMENTS AND THE LOSS OF SOME MENTAL ABILITIES.

MEANS WORSENING CONDITION

TERM USED TO DESCRIBE A GROUP OF GENETIC DISEASES THAT ARE CHARACTERIZED BY PROGRESSIVE WEAKNESS AND DEGENERATION OF THE SKELETAL MUSCLES THAT CONTROL MOVEMENT.

GENETIC DISORDER IN WHICH THE ESSENTIAL DIGESTIVE ENZYME PHENYLALANINE HYDROXYLASE IS MISSING. PKU CAN BE DETECTED BY A BLOOD TEST PERFORMED ON INFANTS AT BIRTH. WITH CAREFUL DIETARY SUPERVISION, CHILDREN BORN WITH PKU CAN LEAD NORMAL LIVES. WITHOUT EARLY DETECTION AND TREATMENT PKU CAUSES SEVERE MENTAL RETARDATION.

IS A FATAL GENETIC DISORDER IN WHICH HARMFUL QUANTITIES OF A FATTY SUBSTANCE BUILD UP IN TISSUES AND NERVE CELLS IN THE BRAIN. BOTH PARENTS HAVE TO HAVE THE MUTATED GENE TO AFFECT OFFSPRING.
