NCSU
Phophase I - ANS-phase in meiosis where crossing over occurs
T.H. morgan - ANS-Scienctist that studied x-linked traits in drosphila mutants
chromatids - ANS-replicated forms of chromosomes joined together by the centromere
dna polymerase - ANS-the enzyme that travels along a template strand of dna and adds
complementary base pairs
metaphase II - ANS-phase in meiosis where chromosomes align along midplate
meiosis - ANS-in algae and fungi, zygotes undergo this to become a multicelled
organism
polygenic inheritance - ANS-when multiple genes are involved in controlling the
phenotype of a trait
dna primase - ANS-enzyme that makes an rna primer to begin dna replication
avery, macleod, and mccarty - ANS-scientists that purified cells to determine that dna
was the inherited molecule
homologues - ANS-chromosomes that have the same genes but not always the same
alleles
single stranded binding protein - ANS-binds to dna to prevent it from reforming a double
helix
frederick griffith - ANS-scientist that studied streptococcus strains to determine what
part of the bacteria was passed from strain to strain
diploid cells - ANS-in most animals, much of the life cycle is spent with cells in this state
mitosis - ANS-in most animals, this process is used to replace cells as they die
, telomerase - ANS-enzyme that adds nucleotides to the ends of chromosomes to
prevent them from shortening
DNA has to be separated and unwound in order to be replicated. Which enzymes assist
with this? - ANS-dna topoisomerase, dna helicase
In certain plants, tall is dominant to short. If a heterozygous plant is crossed with a
homozygous tall plant, what is the probability that the offspring will be short? - ANS-0
in radishes, red and white are pure breeding colors, while heterozygous radishes are
purple. if a purple radish is crossed with a red radish, what fraction of the f1 generation
will be red - ANS-50%
hershey and chase determined which of the following - ANS-dna is the genetic material
transferred from a bacteriophage to a bacteria
arrange the following genetic terms in order to complexity from largest to smallest
1. chromosome
2. nucleotide
3. genome
4. double helix - ANS-3,1,4,2
If I toss a coin 3 times, what is the probability, in fractions, that I will get 1 head and 2
tails (in any order)? - ANS-3/8
when doing a test cross, you will need to use an individual trait that is -
ANS-homozygous recessive for a particular trait
which one of the following statements about DNA is incorrect - ANS-the amount of A in
a double stranded dna is equal to the amount of G
an enzyme called _______ makes one rna primer and ________ attaches nucleotides
in a 5' to 3' direction - ANS-dna primase, dna polymerase
all of the following are characteristics of telomerase except - ANS-has an rna region that
can be used to produce dna
In algae and fungi, organisms spend much of their life cycle as ____________
organisms and
have to undergo____________________ to produce gametes. - ANS-haploid, mitosis
