Summary Introduction

To describe: The three alterations in the genetic codon sequence which will be considered as a neutral mutation.

Introduction: The mutations, which generate a little or negligible alteration in the phenotype of an organism, are called neutral mutations. This type of mutation has minimal effects on the survivability of the organism.

Learning Task 3: TRACE THE CODE dentify the amino acids coded for by the MRNA codon using the Genetic Code Table below. Order of bases in mRNA (codon) AUC Order or bases Order of bases Amino acid Coded in DNA in tRNA into Proteins TAG CAT GC СА UAC Methionine Valine Procedures: Copy and fill in the table Refer to the Genetic Code table to identify the amino acid. To determine the order of bases in the first column (DNA), second column 1. 2. 3. (codon) and third column (anticodon), consider the complementary base pairs in DNA adenine pairs with thymine and guanine pairs with cytosine. 4 Example, AUG using the Genetic Code Table. Look for the first letter of the MRNA codon on the left side of the genetic code table (A). The second letter of the MRNA on the second letter column (U) and the third letter on the right-side column (G). AUG codes for the amino acid methionine. To identify the amino acid. Look at the bases in the MRNA codon. 5. Do the same with the other codons in the chart.…
