GRADED A+
During DNA replication, the leading strand is synthesized
continuously, whereas the lagging strand is synthesized as
Okazaki fragments. Why is this so? - ANSWER-DNA synthesis
can take place only in the 5' to 3' direction.
During DNA replication, an open section of DNA, in which a
DNA polymerase can replicate DNA, is called a _____ -
ANSWER-replication fork
After replication is complete, the new DNAs, called _______
are identical to each other. - ANSWER-daughter DNA
The enzyme that can replicate DNA is called _____ - ANSWER-
DNA polymerase

What are the short sections of DNA that are synthesized on the
lagging strand of the replicating DNA. - ANSWER-Okzaki
fragments
5. The new DNA strand that grows continuously in the 5' to 3'
direction is called the _____ - ANSWER-leading strand
What is the function of helicase in DNA replication? -
ANSWER-It untwists the double helix and separates the two
DNA strands.
What are chromosomes made of? - ANSWER-DNA and proteins
DNA is a self-replicating molecule. What accounts for this
important property of DNA? - ANSWER-The nitrogenous bases
of the double helix are paired in specific combinations: A with T
and G with C.
What characteristics of the structure of DNA allows it to carry a
large amount of hereditary information? - ANSWER-the
sequence of bases

What is the function of DNA polymerase III in replication in E.
coli? - ANSWER-to add nucleotides to the 3' end of a growing
DNA strand
During DNA replication, which of the following enzymes
covalently connects segments of DNA? - ANSWER-ligase
What chromosome consists of a single linear molecule of
double-stranded DNA plus proteins. - ANSWER-eukaryotic
chromosome
If a cell were unable to produce histone proteins, what effect
would likely occur? - ANSWER-The cell's DNA couldn't be
packed into its nucleus.
In gel electrophoresis DNA molecules migrate from _____ to
_____ ends of the gel. - ANSWER-negative ... positive
The flow of information in a cell proceeds in what sequence? -
ANSWER-from DNA to RNA to protein
