Answer:
AUGUCCCACGAUGGGUGA
Methionine- Serine- Histidine- Aspartate- Glycine- Stop
Explanation:
In gene expression, DNA, which is the genetic material is transcribed into mRNA, which is subsequently translated into a amino acid sequence (peptide). The transcription of DNA into mRNA follows complementary base pairing rule i.e. A-U, G-C, T-A.
The nucleotide sequence in the mRNA molecules are read in group of three nucleotide bases called CODONS. Each codon specifies an amino acid.
According to this question, a segment of DNA produces methionine, threonine, histidine, aspartate, and glycine when translated, however, a substitution mutation occurs and causes the synthesis of the segment as shown: 3' – TACAGGGTGCTACCCACT – 5'
The mRNA sequence from this mutated DNA sequence is as follows: AUGUCCCACGAUGGGUGA
During translation, the following codons specify the following amino acids:
AUG - methionine
UCC - Serine
CAC - Histidine
GAU - Aspartate
GGG - Glycine
UGA - Stop codon
Based on this, the new peptide chain when the new DNA segment is translated will be: Methionine- Serine- Histidine- Aspartate- Glycine- Stop
