A mutation in this DNA sequence
ATA CTG AGT CTT CAC yields this new sequence:
ATA CTG ATT CTT CAC.
The amino acids of a protein are linked together by a process called dehydration synthesis. The acid group of one amino acid bonds to the amino group of the next, forming a peptide bond and releasing a molecule of water.
Wool is a protein with alpha helix secondary structure, giving it flexibility and elasticity.
Silk is a protein fiber with beta sheet secondary structure, containing at least four amino acids linked together by hydrogen bonds.
A beta bend allows an amino acid chain to reverse direction by folding back on itself, producing a hairpin turn.
Some amino acid sequences in a protein do not have a structure and take on a random form.
Choose one of these genes:
Perform each of these mutations: (within the promoter TATAATG, or 25-30 bases after the promoter)
