What is the new peptide chain when the new dna segment is translated for 3'- TACAGGGTGCTACCCACT-5'
kakasveta [241]

Answer:

Methionine- Serine- Histidine- Aspartate- Glycine- stop

Explanation:

Translation, which occurs in the ribosomes, is the second stage of protein synthesis where mRNA transcript is used to synthesize a peptide chain that eventually forms a protein. The mRNA sequence is read in a group of three nucleotide called CODON. Each codon specifies a particular amino acid, which is read and added to the growing peptide chain.

In this question, a DNA sequence reds 3'- TACAGGGTGCTACCCACT-5, the

mRNA sequence from this DNA during transcription will be:

AUG UCC CAC GAU GGG UGA

From this mRNA sequence, the peptide chain that will result following translation is:

Methionine- Serine- Histidine- Aspartate- Glycine- stop
