Answer:
The correct answer is A) Proteins in the cell will include lysine instead of phenylalanine at amino acid positions specified by the codon UUU.
Explanation:
If a mutation occurs in the bacterial cell that produces aminoacyl tRNA synthetase that attaches a lysine instead of normal phenylalanine than during the translation process when this tRNA will come opposite to its complementary codon sequence i.e. UUU it will add lysine in place of phenylalanine.
Therefore where ever in the mRNA the UUU codon would be present the mutated tRNA having anticodon AAA bounded with lysine residue will be added. As a result, the protein will include lysine amino acid residue in place of phenylalanine. So the correct answer is A.

Answer:
Explanation:
DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands. This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.

Recombinant DNA technology has also proven important to the production of vaccines and protein therapies such as human insulin, interferon and human growth hormone. It is also used to produce clotting factors for treating haemophilia and in the development of gene therapy. hope that helps
