front 23 What is the difference between a haploid(n) and diploid(2n)? | back 23 haploid(n)- a single set of chromosomes diploid(2n)- cells that have 2 sets of chromosomes |
front 24 Mitosis/cytokinesis start and end with what? | back 24 They both start and end with a diploid |
front 25 What is the basic function of the cell cycle? | back 25 to duplicate DNA in chromosomes and separate the copies of the identical cell daughters. |
front 26 The majority of a cells life is spent where? | back 26 interphase (90% of the time) |
front 27 Interphase of mitosis is split into what periods? | back 27 G1, S, and G2 |
front 28 What is the G1 phase? | back 28 the cells begins to grow larger. decondensed chromosomes, mass of chromatin |
front 29 What is the S phase? | back 29 Where the chromosomes are replicated double-stranded chromosome, identical 2nd arm (sister chromatid |
front 30 What is the G2 phase? | back 30 where the cell prepares to divide by mitosis enzymes and proteins synthesize to prepare for cell division |
front 31 What is cytokinesis? | back 31 When the cell cycle is completed (after mitosis) and the cytoplasm divides. |
front 32 How many restriction points(checkpoints) are there in cell division? | back 32 3 |
front 33 What are the safeguards in the checkpoints? | back 33 They are proteins called cyclin-dependent kinases or cdks |
front 34 What occurs during the s phase? | back 34 chromosomes have a double stranded helix of DNA. |
front 35 What happens during the s phase? | back 35 the 2 strands of DNA helix unwind and separate and each are replicated. By the end there are 2 helixes of DNA called chromatids. |
front 36 What are centromeres? | back 36 where chromatids are joined together(the waist) |
front 37 When do spindle fibers begin to assemble? | back 37 During G2 phase |
front 38 Human somatic cells have how many chromosomes? | back 38 46 - diploids |
front 39 Human sperm/ova cells have how many chromosomes? | back 39 22 somatic plus 1 sex/gamete chromosome – haploid |
front 40 What are the phases of mitosis? | back 40 PMAT (prophase, metaphase, anaphase, telophase) |
front 41 What happens in prophase? | back 41 chromosomes pair up(condense), nuclear membrane disappears, and the miotic spindle begins to form. |
front 42 What happens in metaphase? | back 42 Chromosomes line up in the middle using the spindle fibers. (centrioles play an important role) |
front 43 Do plants and animals have spindle fibers? | back 43 yes |
front 44 Do plants and animals have centrioles? | back 44 No, only animals do. |
front 45 What are centrioles? | back 45 They are small structures made up of microtubules that help organize them. They are also part of the centrosome. |
front 46 What happens during anaphase? | back 46 The sister chromatids are pulled apart. The chromatids are now called daughter chromosomes. |
front 47 What happens during telophase? | back 47 The cell pinches to the middle allowing to cells to begin to form. The nuclear membrane begins to form, spindle fibers/centrioles disappear, and chromosomes begin to uncoil. |
front 48 What happens during cytokinessis? | back 48 The cytoplasm divides and two identical daughter cells are made. |
front 49 What happens in a plant cell during cytokinesis? | back 49 A cell plate is formed |
front 50 Mitosis is... and meiosis is... | back 50 asexual and sexual reproduction |
front 51 What is meiosis? | back 51 Sexually reproduction using gametes (sex cells) containing half the normal number of chromosomes (haploids). |
front 52 How many rounds of division can meiosis go through? | back 52 2 (compared to mitosis which can only go through 1) |

front 64 How many chromosomes do diploid cells have? | back 64 46 |
front 65 How many chromosomes do haploid cells have? | back 65 23 |
front 66 What is Mendel's law? | back 66 Because organisms have pairs of homologous chromosomes, they also have pairs of genes (Punnett square) |
