kipiarov [429]

In response to an increased workload, cardiac myocardial cells will increase in size. Myocardial cells are the muscle cells within the heart. These cells naturally increase in size as the heart enlarges during development. The cells can also grow during extensive exercise, heart disease, or due to an injury to the heart muscle (such as a heart attack).

Explanation:

Some of the sequence of DNA given is in 3' to 5' direction, mRNA sequence is also given.

The DNA is double stranded helix which replicates by semi conservative mode. The two strands unwind to act as a template for other strands. In transcription the 3' to 5' strand acts as a template because RNA synthesis takes place in 5' to 3' direction. mRNA is single strand. It has nucleotides in it from which 3 base pairs acts as a code for amino acid.

The following table shows DNA strand having complementary sequaence and mRNA synthesized.
