A
gene
3
Q
define gene mutation
A
a change in the sequence of nucleotides that may result in an altered polypeptide
4
Q
The steps of protein synthesis are…
A
1) Transcription
2) Translation
5
Q
mRNA
A
- RNA used in transcription
- carries genetic information copied from DNA in the form of a series of three-base codons, each which specifies an amino acid
6
Q
tRNA
A
- RNA used in translation
- helps decode a mRNA sequence into a protein
- function at specific sites in the ribosome during translation
