which of the following is the most likely explanation for how a mutation in the dnadna could result in the loss of the carboxyl terminus of the hbbhbb protein? responses the mutation keeps the hbbhbb gene wrapped tightly around histones, preventing transcription of the gene. the mutation keeps the h b b gene wrapped tightly around histones, preventing transcription of the gene. the mutation changes the promoter sequence of the gene such that different transcription factors initiate transcription of the gene. the mutation changes the promoter sequence of the gene such that different transcription factors initiate transcription of the gene. the mutation changes a codon in the coding region of the hbbhbb transcript to a stop codon such that translation terminates earlier than it should. the mutation changes a codon in the coding region of the h b b transcript to a stop codon such that translation terminates earlier than it should. the mutation results in hydrogen bonds between adjacent amino acids instead of covalent bonds, resulting in the production of an unstable protein.
