Summary Introduction

To explain:

The evolutionary pattern regarding the coding of most amino acids by a set of similar codons.

Introduction:

The unit of genetic code, which has three nucleotides that code for amino acids, is called codon. The mRNA (messenger ribonucleic acid) got attached to the ribosomal complex in the cytoplasm. The transfer RNA conveys amino acids to the ribosomal complex where the pairing of an anticodon of tRNA (transfer ribonucleic acid) takes place with complementary codon of the messenger RNA. The formed amino acids get linked and form proteins.

Use this mRNA coding sequence as your starting point. This sequence begins with a start codon and ends with a stop codon, so it is only looking at the region of DNA that directly encodes a protein sequence. 5’-AUGCACAAAUUAGAGUACCCCCCAGGAAGGUAG-3’ Make the following mutation in this sequence by changing/adding/removing only one nucleotide. Make the mutation easy to see (a different color, circled, something like that) A missense mutation that is also a transversion
