Chapter 3 (Biological Molecules) Flashcards
1
Q
What are the nucleotide base pairings?
A
Thymine + Adenine
Cytosine + Guanine
2
Q
Which nucleotides are pyrimidines?
A
Pyrimidines are the nucleotides with only one carbon ring.
This group includes thymine and cytosine
3
Q
Which nucleotides are purines?
A
Purines are the nucleotides with 2 carbon rings.
This group includes adenine and guanine.
4
Q
In which direction does DNA polymerase travel in?
A
DNA polymerase only travels along the template strand in the 3’ to 5’ direction, which results in the lagging strand being replicated in sections called Okazaki fragments.
5
Q
What is a polymer?
A
A polymer is a molecule made up of more than 2 monomers
6
Q
What are reducing sugars?
A
Reducing sugars donate electrons to other molecules, reducing them
