Answer:
Approximately six
Explanation:
The codon GGU
Single base substitution that will change this codon that codes for glycine to another amino acid includes: a single base substitution in the GGU codon such as GGU- AGU can occur. thus, approximately six single base substitution can take place to change this codon to code for another amino acid. A single base substitution cannot change the codon to a stop codon unless it happens twice or there is more than a single base substitution.
What would happen if M RNA were radio actively labeled instead of polypeptides is that instead of one seeing the DNA passing through all the molecular factories you will instead see just messenger RNA taking code and delivering it to Ribosome. This is mainly found in cytoplasm and Endoplasmic recticulums.
The answer would be D.
Enzymes activity increases as the temperature increase so, therefore the answer would be D.
but to be fair they all would work.
