Answer
DNA - Deoxyribonucleic acid is a long molecule that contain our
unique genetic code .
each strand is composed of long sequence of the Four bases
A,C,G,T
How
semi conservative DNA replication prevent mutation? why
semi-conservative dna replication is more important than
conservative replication? thank you
Why is DNA replication called a semi-conservative mechanism?
What is the difference between the leading and the hesitant
(lagging) thread in DNA replication, and why must a leading and a
lagging thread be formed?
What are the origin site, topoisomerase/gyrase, and primer
respectively
connection with the replication?
What function does helicase (DnaB) and DNA polymerase III
have
replication?
What do DNA polymerase I and ligase contribute to?
What is the difference between transcription and DNA
replication?
In what phase of the cell cycle does DNA replication
occur?
What is the difference between Mitosis and cytokenesis?
Give the function of the following:
DNA polymetase
Helicase
binding proteins
ligase
primase
What is a sister chromatid?
What is the function of a centrosome?
What does “semi-discontinuous” DNA replication mean? Explain in
words how the lagging DNA strand is replicated in bacteria. What
specific enzymatic activities does DNA polymerase I have? Name each
activity and explain its role in DNA replication. If DNA polymerase
I lacked its 3’-5’ exonuclease activity, what specific consequences
with respect to DNA replication would be observed? What
consequences would be observed if, instead of DNA pol I, DNA
polymerase III lacked its 3’-5’ exonuclease activity? Explain your
answers.
For each phase of the cell cycle,: G1 Phase - Growth, S PHase -
DNA Replication, G2 - Growth, M Phase - Mitosis) state what the
overall (general) histone methylation state OR acetylation state
of the inactive X (Xi) and active X (Xa) chromosomes in
human females.
Xi Xa

a diploid human cell contains approximately 6.4 billion base
pairs of dna. how many histone proteins are complexed to this dna?
I know the answer is 2.9 x 10^8 but do not know how to start
it.
