I believe the answer is X chromosome and Y chromosome.
The bonds that hold the two chains of an insulin molecule together are two disulfide bonds.
Insulin molecule is made up of two peptide chains. These chains are referred to as the A and B chains. The A and B chains are help together by the two disulfide bonds present between them. The A chain has an additional disulfide bond inside it. The A chain is 21 amino acids long and the B chain is 30 amino acids long in most of the species.
<span>Yes , it is true... Hopes this helps </span>
The process that produces oxygen
is the photosynthesis and when oxygen is released as the result of its production during
photosynthesis, it is a
by-product of splitting the water molecules. The reduction of oxygen which forms water occurs during
respiration.
There are so many examples for that in different areas, like biology experiment carried out in our lab recently.
