Question

What are the nitrogenous bases (adenine, thymine, cytosine, guanine) responsible for?

Answer 1

nitrogenous bases are used as the units in the genetic code of DNA

Explanation:

These bases are the units in the universal code that all living organisms use.

In morse code the units are dots (.) and dashes (-) arrangements of these unit spell out different letters such (...)( ---)( ... ) equals SOS

Arrangements of the nitrogenous bases spell out different letters and instructions on the DNA usually in codons or groups of three bases. These codons are arranged on large macromolecules called Chromosomes. The sequence of codons provide the instructions for the building of proteins and entire organisms.

These information- rich macromolecules direct the metabolism and machinery of living things. ( Signature of the cell page 111)

So the nitrogenous bases are responsible for the information and instructions that all living things depend on.
