Biology B Final Exam Review
why does a cell divide? - correct answer -the surface area can't contain as much, not enough DNA, and
the cell gets too big
When does a cell divide? - correct answer -When it gets too big, when there are enough cells to divide
evenly
what are the cell cycle stages (only two) - correct answer -interphase-no divide, Mitosis-divide
inside of the m phase are what four stages? - correct answer -prophase, metaphase, anaphase,
telophase. (cytokenisis)
what are the three stages of interphase? - correct answer -G1, S phase, G2
what does diploid mean and which cells are considered diploid? - correct answer -"Di" means two, so a
diploid is two sets of chromosomes. Sex cells are considered diploid
what is a gamete? - correct answer -sex cells, egg and sperm
does a crossover event always happen? - correct answer -yes in some form
what is the difference between an allele and a gene? - correct answer -a gene comes FROM alleles
in which stage of mitosis does cross over happen? - correct answer -prophase of meiosis 1
in mendel`s experiment, what does P, F1, and F2 mean? - correct answer -parent, first generation,
second generation
, when does a cell lose its nuclear envelope? - correct answer -when it splits in two
what is the difference between a trait and a gene? - correct answer -trait is a specific characteristic,
genes determine traits
what is a recessive trait and what is a dominant trait? - correct answer -recessive is weak and dominant
is overpowering
what is an allele? - correct answer -different forms of genes
what is the difference between homozygous trait and a heterozygous trait? - correct answer -same traits
true born. different traits 2 parents
what is cell division called? - correct answer -mitosis
what are the new cells called? - correct answer -daughter cells
what does each daughter get? - correct answer -DNA and a nucleus
what is the difference between a chromosome, chromatid, and a chromatin? - correct answer -a
chromosome is a pair of condensed DNA molecules. Chromatin is uncondensed DNA. Chromatids are
half of a chromosome
what are the stages of interphase? - correct answer -S phase and G2
what regulates cell growth? - correct answer -Cyclin
A plant cell forms what between two new nuclei after cell division? - correct answer -Cell plate ---> cell
wall
