How many types of nucleotides are in dna, and how do they differ?
Question: How many types of nucleotides are in dna, and how do they differ?
There are four types of nucleotides in DNA, and they differ based on their nitrogenous bases. The four nucleotides are:
1. Adenine (A) - Adenine forms a base pair with Thymine (T) in DNA.
2. Thymine (T) - Thymine forms a base pair with Adenine (A) in DNA.
3. Guanine (G) - Guanine forms a base pair with Cytosine (C) in DNA.
4. Cytosine (C) - Cytosine forms a base pair with Guanine (G) in DNA.
The order or sequence of these four nucleotides determines the genetic information stored in the DNA molecule. The base pairing between A and T, and G and C, provides the stability to the double-stranded DNA helix structure. The specific sequence of nucleotides is responsible for encoding the genetic instructions for the development and function of all living organisms.
