ls7a nucleic acids & transcription + protein structure

nucleotide

Subunit of which nucleic acids are composed

How many hydrogen bonds do A & T have

2

How many hydrogen bonds do G & C have

3

primary protein structure

sequence of amino acids

secondary protein structure

Folded patterns within a polypeptide chain

tertiary protein structure

long range interactions between secondary structures

quaternary protein structure

interactions between individual polypeptides

where are codons found

mRNA

where are anticodons found

tRNA

point mutations

changes in a single nucleotide pair of a gene

silent mutations

if a mutation changes a codon but it still codes for the same amino acid (redundancy), resulting no change to protein

missense mutations

nucleotide substitution resulting in an amino acid replacement, resulting in changing the protein function

nonsense mutation

creates stop codon prematurely terminating translation

frameshift mutations

insertion of 1 nucleotide that causes shift in all nucleotides in reading frame, causing non-functional protein
