Term
Transcription
Definition
The transfer of DNA into an RNA molecule.
Term
Translation
Definition
The transfer of information in the RNA into a protein.
Term
Codon
Definition
3 Nucleotide bases that code for an amino acid.
Term
RNA polymerase
Definition
A Transcription enzyme that links RNA nucleotides
Term
Promoter
Definition
A Specific binding site for RNA polymerase that acts as the "start transcribing"signal.
Term
messenger RNA (mRNA)
Definition
It conveys genetic information from the DNA to the translation machinery of the cell.
Term
Exon
Definition
The coding regions for amino acids.
Term
Intron
Definition
Noncoding regions
Term
RNA splicing
Definition
The cutting and pasting process that cuts out introns. It occurs in the nucleus.
Term
Transfer RNA (tRNA)
Definition
Converts mRNA sequence to amino acids.
Term
Ribosomal RNA (rRNA)
Definition
makes up 2 subunits of the Ribosome. It has tRNA binding sites and a mRNA binding site for polypeptide sequencing to occur.
Term
P site
Definition
Holds the growing polypeptide in tRNA.
Term
A site
Definition
Vacant for the next anticodon of tRNA.
Term
mutation
Definition
Any change in the sequence of DNA
Term
mutagenesis
Definition
change in the reading frame of DNA
Term
mutagen
Definition
A physical or chemical agent that causes a mutation.
Term
Capsid
Definition
Protein coat of a Virus.
Term
Lytic Cycle
Definition
Reproductive cycle of Viruses that break open the host cell.
Term
Lysogenic Cycle
Definition
DNA replication of Viruses occurs without destroying the host cell.
Term
Reverse transcriptase
Definition
HIV enzyme that is able to synthesize DNA on a RNA template.
