1.
The enzyme that unzips the DNA double helix so replication can begin.
2.
Builds the RNA primer so DNA polymerase has a place to start.
3.
Seals gaps and joins DNA fragments together like "glue."
4.
Relieves tension ahead of the replication fork by cutting and twisting DNA.
5.
The strand that is copied continuously toward the replication fork.
6.
The strand copied in short pieces because it runs in the opposite direction.
7.
The short pieces of DNA made on the lagging strand.
8.
The original DNA strand used as a guide to build the new one.
9.
A DNA building block made of a sugar, phosphate, and base.
10.
A bond with weak attractions that hold complementary bases together.
11.
strong bonds connecting the sugar-phosphate backbone.
12.
A short RNA piece needed to start DNA synthesis.
13.
The two DNA strands run in opposite directions.
14.
Enzyme that rebuilds chromosome ends so important DNA isn't lost.
15.
Repetitive DNA at chromosome ends that protect genetic information.
16.
Repair that Fixes errors after DNA replication finishes.
17.
Repair that Removes damaged DNA bases (such as from UV light).
18.
Making RNA from DNA (often mistaken for replication!).
19.
Making proteins from mRNA at the ribosome.
20.
A mutation where a purine is replaced with a pyrimidine, or vice versa.
