Adenine
Uracil
DNA replication occurs ___________________________.
in the s phase of interphase
_________________ is the sugar that’s found in _____________.
Ribose, DNA
Deoxyribose, RNA
Deoxyribose, DNA
Which of the following is NOT one of the parts of a nucleotide?
nitrogenous base
sugar
phosphate group
none of these
Which of the following best describes the leading strand in DNA replication?
the leading strand is replicated in chunks called Okazaki fr
none of these
the leading strand is replicated discontinuously
the leading strand is replicated continuously
In DNA, Adenine always pairs with ___________________.
Thymine
Cytosine
Guanie
Uracil
DNA polymerase can only lay down base pairs in a ______________________ direction.
5' - 3' direction
Which of the following scientists helped contribute important information relating to DNA?
Wilkins
Watson & Crick
All of these
Franklin
What is the correct order of the steps of DNA Replication?
Initiation, elongation, termination
In DNA, Guanine always pairs with ___________________.
Cytosine
Describe what is meant by complementary base pairing.
complementary base pairing; A pairs with T & vice versa, and G pairs with C and vice versa
Draw the basic structure of a single nucleotide (i.e. you need to include the 3 parts of a nucleotide).
Drawing Needs to have a sugar, phosphate group, nitrogenous base
What does the term “semi-conservatively” mean? How does it related to DNA replication?
each strand of the original double helix serves as a template for the new DNA strand being replicated during DNA replication.
Describe Chargaff’s Rule and how it relates to DNA.
Chargaff’s Rule states that because of complementary base pairing, the number of complementary base pairs will be equal
Which enzyme unzips the DNA strand?
Helicase
Which enzyme add RNA primers to the DNA strand
Primase
