Answer:

bases.

Explanation:

Nucleotides are the basic building blocks that make up DNA, consisting of a deoxyribose sugar, phosphate group, and nitrogenous base. The main difference between the four nucleotides is the nitrogenous base, Adenine, Thymine, Guanine, or Cytosine. Adenine pairs with Thymine, and Guanine pairs with Cytosine. The order in which these pairs come in code for proteins and hold genetic information.

1.<br> Describe two advantages of genetic engineering.
Novay_Z [31]
One advantage of genetic engineering is the production of valuable proteins: recombinant DNA made possible the use of bacteria to produce proteins of medical importance such as genetically engineered human insulin which is of great importance.
Another advantage is the production of vaccines. Vaccines produced by genetic engineering offer an advantage that the microbial strains from which proteins are extracted do not contain complete viruses and thus there is no risk of accidental inoculation with live virus.
