<span> The answer is a misense mutation. In this case, the substitution of the tryosine amino acid with cysteine in the same position in the sequence does not affect the polypeptide becasue both tryosine and cysteine are polar animo acids. If the substitution </span><span><span> in the polypeptide chain </span>was by amino acids with different properties, it would affect the folding of the protein and change its conformation hence also affect its function. </span>
<span>The mutation did not affect amino
acid sequence or the molecular weight (no evidence of amino acid substitution
or protein truncation). Therefore, the mutation is not likely within the coding
region of the gene. Most likely the
mutation is in the regulatory region of the gene such as the promoter region.
Such mutation would interfere with transcription initiation and hence decreases
the amount of mRNA and protein produced. </span>
Answer:
particular products for now you can call me if you can I
Answer:
A molecule of the kind normally found in living systems. Organic molecules are usually composed of carbon atoms in rings or long chains, to which are attached other atoms of such elements as hydrogen, oxygen, and nitrogen.
