Biol 105 Final Lab Exam IVY
Tech with 100% correct
answers (graded A+)
Zygote? - answer a diploid cell resulting from the fusion of two haploid
gametes; a fertilized ovum.
What does mitosis do? - answer Makes new cells for growth and repair
What is Cancer ? - answer uncontrolled cell division
G1 phase - answer metabolic activities, building up and breaking down
macro molecules, this also the phase that initiates mitosis
S phase - answer The synthesis phase of the cell cycle; the portion of
interphase during which DNA is replicated.
Centromere - answer Region of a chromosome where the two sister
chromatids attach
G2 phase - answer Growth and preparation for cell division
M-phase - answer The phase of the cell cycle that includes mitosis and
cytokinesis.
crossing over - answer exchange of genetic material between homologous
chromosomes during prophase I of meiosis
, synapsis - answer the fusion of chromosome pairs at the start of meiosis.
Heterozygous - answer An organism that has two different alleles for a trait
Homozygous - answer An organism that has two identical alleles for a trait
Dominant - answer An allele that is always expressed
Recessive - answer An allele that is masked when a dominant allele is
present
Trait - answer A characteristic that an organism can pass on to its offspring
through its genes.
Phenotype - answer An organism's physical appearance, or visible traits.
Genotype - answer An organism's genetic makeup, or allele combinations.
Allele - answer Different forms of a gene
Gene - answer A segment of DNA on a chromosome that codes for a specific
trait
spontaneous generation - answer the mistaken idea that living things can
arise from nonliving sources
Biogenesis - answer the production of living organisms from other living
organisms
