The base sequence of a polynucleotide chain is given as follows. This is the template strand of a DNA molecule. Please answer the questions following the base sequence.

3’-TAC GGG CTA CAA CTT AAC AGA CCA ATC-5’

  1. What will be produced if this DNA molecule is replicated?
  2. What are the anticodon sequences of the tRNA molecules that can carry these amino acids?
  3. If this DNA got a mutation that changed the first 3 bases to 3'-ATT-5', what will happen to the polypeptide chain to be synthesized?

Solutions

Expert Solution

Ansa) DNA replication results in two new DNA double helix  in which each double helix consist of one parental strand and another new daughter strand. As DNA replication is semiconservative in human.

Ans-c) mutation in first three bases stop the translation process.
