Answer:
Deletion and glycosylation.
Explanation:
Proteins is polymers of the alpha amino acids that are directly linked together through the peptide bond. Proteins plays an important role in the metabolic pathways as most enzymes are made of protein.
The same protein can exist in two different size. This might occur due to the deletion of the particular amino acids sequence in one organism and normal in other organisms. The glycosylation of the same protein at different position in the proteins may also leads to the difference in the protein size.
Thus, the correct answer is deletion and glycosylation.

<h2>Answer:</h2>
The correct statement is option A which is, "A gene is a segment on the DNA. DNA is wrapped in proteins to form a chromosome".
<h3>Explanation:</h3>
- A gene is the part of DNA in the nucleus which encodes for the specific trait in the body. DNA is the nucleotide sequence which is the blue print for the whole organism. It contains genes for all the structures and functions in the body.
- So it is very long sequence containing the million of genes. So in nucleus it is present in compress form. It is wrapped on the histones proteins and condense and supersondense into a specific structure which is known as chromosome.
