Which part of a dna molecule is responsible for the direct coding of specific traits in an organism?

Genes are the hereditary units of all organisms. Genes play crucial role in regulating the expressions of an individual. Genes are present on the DNA molecules that are responsible for the direct coding of specific traits in an organisms.

Explanation:

Genes are the coded sequences found in DNA nucleotides. The genes code for particular proteins and determine the phenotypic characteristics of an individual. The phenotypic traits are physical and observable. Hair color, height, skin color, and ay disease are regulated by the genetic make-up of an individual. The genes that are dominant in nature are expressed, whereas the recessive genes are masked by the dominant genes.

Therefore, the genes are the coded sequence of nucleotides that are responsible for the direct coding of specific traits.

Explanation:

Nucleotides are molecules present in cells formed by nitrogenous bases, phosphate and pentose. They are responsible for the direct coding of specific characteristics of an organism.

Most nucleotides are found together, forming nucleic acids. A small fraction of nucleotides occurs freely.

They participate in many reactions of cellular metabolism, of which the following stand out:
