RNA
Ribonucleic acid
4
New cards
Chromosomes
Structures made of DNA
5
New cards
Nucleotides
Consist of a five carbon sugar (deoxyribose), phosphate group, and a nitrogenous base
6
New cards
Purines
Nucleotides with a double ring structure (A - adenine, G - guanine)
7
New cards
Pyrimidines
Nucleotides with a single ring structure (C - cytosine, T - thymine)
8
New cards
Antiparallel Strands
Two strands of DNA that run in opposite directions and interact to form a double strand
9
New cards
Double Helix
The twisted structure formed by two strands of DNA
10
New cards
Semiconservative Replication
DNA replication process producing molecules with both old and new DNA strands
11
New cards
Origins of Replication (prokaryotes)
o A single origin of replication
12
New cards
o Two replication forks
13
New cards
o Possible because of small size
14
New cards
DNA Polymerase
Enzyme that adds nucleotides to the 3' end of a primer during DNA replication
15
New cards
Leading Strand
New DNA strand synthesized continuously in the 5' to 3' direction
16
New cards
Lagging Strand
New DNA strand synthesized discontinuously in short fragments
17
New cards
Replication Bubble
Region where DNA replication occurs
18
New cards
Telomeres
Sacrificial DNA ends that prevent the loss of important genetic information during replication
19
New cards
Telomerase
Enzyme that restores telomeric DNA ends in continuously dividing cells
