IDENTIFIED ANSWERS[GRADED A+]
The process of DNA replication requires that each of the parental DNA
strands be used as a _____ to produce a duplicate of the opposing
strand - ANS-(c) template
DNA replication is considered semiconservative because - ANS-(c)
each daughter DNA molecule consists of one strand from the parents
DNA molecules and one new strand
(d) true, but not correct - new DNA strands must be copied from a DNA
template
The classic experiments conducted by Meselson and Stahl
demonstrated that DNA replication is accomplished by employing a
mechanism - ANS-(b) semiconservative
If the genome of the bacterium E. coli requires about 20 minutes to
replicate itself, how can the genome of the fruit fly Drosophila be
relocated in only 3 minutes? - ANS-(d) Drosophila DNA contains more
origins of replication than E. coli DNA
6-6 - ANS-
(A) When DNA is being replicated inside a cell, local heating occurs,
allowing the two strands to separate
(B) DNA replication origins are typically rich in G-C base pairs
(C) Meselson and Stahl ruled out the dispersive model for DNA
replication
(D) DNA replication is a bidirectional process that is initiated at
multiple locations along chromosomes in eukaryotic cells - ANS-(A)
FALSE - the two strands do need to separate for replication to occur
but this is accomplished by the binding of initiator proteins at the
origin of replication
(B) FALSE - DNA replication origins are typically rich in A-T base pairs,
which are held together by only two hydrogen bonds (instead of three
for C-G base pairs), making it easier to sepa
