Question

Using the model of a process above, identify the molecule that is shaded in purple and its function.

Answer 1

Answer:

In the image, the coding strands and the template strands are depicted in orange and purple respectively.

Explanation:

The second important function of genetic material is to direct the physiological activities of the cell. Most catalytic and functional roles in the body are carried out by peptides, proteins and RNA. The structure and function of these molecules is determined by nucleotide sequences in DNA.

When a protein or RNA molecule needs to be produced, the first step is transcription. Like DNA replication, this begins with the transient formation of a single-stranded region. The single-stranded region then acts as the template for the polymerization of a complementary polynucleotide RNA molecule. Only one of the two strands of DNA is involved in transcription. This is called the template strand and the other strand is called the coding strand. Since transcription is also dependent on complementary base pairing, the RNA sequence is nearly the same as the coding strand.
