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.
Answer:
Retroviruses or reverse transcriptase
Explanation:
Retroviruses are viruses in which the genetic material consists of ribonucleic acid (RNA) instead of deoxyribonucleic acid (DNA). Retroviruses produce an enzyme known as reverse transcriptase that uses RNA as a template to manufacture DNA, which can then be permanently integrated into the DNA of the infected host cells.
