DNA Replication
What is the name of the enzyme involved in DNA replication?
DNA polymerase
What is the diploid number?
number of chromosomes in a somatic cell
What is the difference between sexual and asexual reproduction?
pass on all of your dna vs pass only half of your dna
What is an allele?
different versions of a gene
Which enzyme opens up DNA?
helicase, topoisomerase
What is the haploid number?
number of chromosome in a germ cell (sperm or egg)
What is the life cycle
sequence of stages from generation to generationfro conception to production of offspring
What is a recessive allele
in the heterozygote, the allele whose phenotype you don't see
Which enzyme joins Okazaki fragments together ?
ligase
What are all the stages of mitosis
interphase, prophase, prometaphase, metaphase, anaphase, and telophase
How does life cycle differ between animals, plants, and fungi?
animals - dominant diploid multicellular form
fungi - haploid multicellular
plants - both diploid multicellular and haploid multicellular
What does homozygous mean
Which enzyme creates and destroys the RNA primer
primase; RNase
What is cytokinesis
end of mitosis, cell divides into two
What is the purpose of meiosis?
reduce chromosome numbers from 2n to n
What is codominance?
when you see both of the alleles in equal amounts
What exists at the ends of chromosomes to resolve the "end-replication problem"
telomeres
What are the different stages of the cell cycle and what happens in each stage
G1 & G2 - "growth" / "gap"
S - synthesis
What is the independent assortment?
maternal and paternal sets of chromosomes can assort independently
What is Mendel's law of segregation?
two alleles for a character seperate during gamete fromation and end up in different gametes
