Phantasy [73]

Unoxygenated blood from veins enters the right atrium then it goes down to the right ventricle then out through the pulmonary artery to the lungs where it becomes oxygenated blood which then enters the heart through the pulmonary veins and it goes to the left atrium and then is pumped down to the left ventricle and out through the aorta to the arteries where it travels to different organs and becomes deoxygenated and then the cycle repeats itself.

In a DNA molecule, the complementary strand is the one composed of bases that pair -complement- the bases of the original strand. The complementary strand is TACCCGATCAGAA.

<h3>What is a complementary strand?</h3>

During DNA replication, the molecule unwinds and the two strands are separated. These are the original strands.

Once the strands are separated, the elongation process begins, in which new nucleotides are added to complement each of the original strands.

A DNA molecule grows composed of an old existing strand, which is used to synthesize the new complementary strand.

After DNI replication each new molecule carries an original DNI strand and a new one.

So, the complementary strand is the new one composed of bases that pair the bases from the original strand.

In DNA molecules, Adenine pairs Thymine, and Cytosine pairs Guanine.

In the exposed example,

Original strand ⇒ ATGGGCTAGTCTT

Complementary strand ⇒ TACCCGATCAGAA
