what are the 3 parts of the nucleotide and which one is responsible for traits?
The three parts of a nucleotide are:
1. Nitrogenous Base: There are four possible nitrogenous bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, uracil (U) replaces thymine. The sequence of nitrogenous bases in a nucleotide determines the genetic code and instructions for building proteins.
2. Sugar: The sugar component of a nucleotide is either deoxyribose in DNA or ribose in RNA. The sugar provides the backbone structure for the DNA or RNA molecule.
3. Phosphate Group: The phosphate group is responsible for linking nucleotides together, forming the backbone of DNA or RNA.
The nitrogenous base is the part of the nucleotide that is primarily responsible for traits. The specific sequence of nitrogenous bases in DNA determines the genetic information that is passed on from parents to offspring and plays a crucial role in determining an organism's traits.
