| Term | Definition |
|
Lagging strand |
The fork of DNA during replication that takes longer to replicate due to the more complex way it must be replicated |
|
DNA polymerase |
Enzyme that assists in DNA replication by adding matching nucleotides to a replicating (forked) string of DNA |
|
Helicase |
Enzyme that “unzips” the 2 strands of DNA (or RNA-DNA hybrid). |
|
Primase |
form of RNA Polymerase that binds to the DNA helicase and helps initiate the synthesis of DNA strands |
|
Topoisomerase |
enzyme that acts on the topology of DNA and help “unknot” the DNA. |
|
Gyrase |
Type of Topoisomerase that introduces negative supercoils (or relaxes positive supercoils) into DNA (helps break it up). |
|
RNAse |
Nuclease that catalyzes the hydrolysis of RNA into smaller components. |
|
DNA ligase |
ligase (type of enzyme) that helps link together DNA with double strand breaks. |
|
Origin of replication |
DNA sequence that indicates where DNA replication should begin |
|
Bidirectional replication |
Type of DNA replication where replication occurs in 2 directions from the starting point. |
|
Telomerase |
enzyme that adds repeating sequences of DNA to the 3’ (3 prime) ends of DNA. |
|
mRNA |
messenger RNA, involved in protein production. Acts as a kind of blueprint (makes a copy of the gene it will be using to create the protein and brings it to the ribosome) |
|
rRNA |
ribosomal RNA, translates the genetic sequence given by the mRNA into amino acids and gives this information to the tRNA. |
|
tRNA |
transfer RNA, brings the ribosome amino acids to build cells with. |
|
Codon |
sequence of 3 nucleotides that determine the amino acid that the tRNA should deliver. |
