The genome is the sum of all genetic material in a cell or virus.
In semi-conservative replication, the resultant strands of RNA are identical to the original strands.
The RNA which takes information from the nuclear genome to the ribosome is mRNA.
The anticodon is located on the rRNA.
The operon is a series of genes controlled by one regulatory gene.
The promoter is the region of mRNA where transcription of a gene begins.
A mutation is any change in the base pairs of a tRNA.
A frame shift mutation could be either the insertion or deletion of one of more base pairs.
A restriction endonuclease is an enzyme that is naturally present in cells and that cleaves a specific location on DNA.
