Ovules produced by an entirely green plant contain a rare mutation in a nuclear gene that is involved in chlorophyll synthesis,
sveticcg [70]

Answer:

The plant will produce less chlorophyll

Explanation:

The plant still has a functional allele provided by the paternal gamete, thereby the leaves have this enzyme required for chlorophyll biosynthesis. In consequence, the plant can produce chlorophyll pigment but in less quantity, since it has only a functional allele coding for a key enzyme involved in the chlorophyll pathway

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
