Explanation:

DNA, also known as deoxyribonucleic acid, is a molecule that holds genetic information needed to make other molecules in living organisms. However, before this genetic information can be harnessed, it needs to be expressed via two processes called transcription and translation.

Transcription is the first of the two processes that take place during genetic expression. It involves the synthesis of mRNA molecule from a DNA template. In other words, the DNA must first be TRANSCRIBED into mRNA.

In this process food is broken down into forms that can be absorbed by the body . food is broken down by the teeth and the enzymes in saliva,when it is in the mouth. From there it moves to the stomach through the oesophagus. In the stomach, the content is further mixed with enzymes and the churning breaks down food further.From the stomach food moves to the small intestine. In the small intestine, digestive enzymes from the pancreas and liver acts on food. The small intestine is where digested food is absorbed.it has a large surface area and finger-like projection called villi to carry out the function of absorbing nutrients.

From there, undigested food us passed to the large intestine from where it is passed out through the anus

blagie [28]

Answer:

CGTCATC

Explanation:

In a DNA double helix, the complementary bases of two strands of DNA are paired by hydrogen bonds. Adenine of one DNA strand is paired with the thymine of the other strand. Similarly, the guanine of one DNA strand is paired with the cytosine of the other DNA strand. If a portion of one of the two strands of a DNA molecule has the sequence GCAGTAG. The sequence of the other strand would be as following:

One DNA strand: GCAGTAG

Other DNA strand: CGTCATC
