The Meselson-Stahl experiment used DNA containing 14N and 15N to show that DNA replication is semi-conservative. If replication

had been conservative (i.e., one double helix formed of 'old' DNA, and one completely new double helix), what would have been the expected outcome of the experiment after one round of replication.

Answer:

After one round of replication, there will be only two layers one of 14 N and second of 15 N labelled. This is because of total conservation of template. If it was semi-conservative then an intermediate layer will be formed composed of one strand of 14 N and other strand of 15 N. This intermediate strand did not appear in this conservative replication state.

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
