Genes and RNA transcripts differ in length. Intron Size of RNA transcript Exon Size of gene (DNA) Refer to figure above. The mRNA is smaller than the length of the DNA that codes for it because the regulatory regions (introns) of the gene are not transcribed. post-transcriptional modification removes the introns. bases are added to the tail of the primary transcript. post-transcriptional modification removes the exons.

Gene Interactions

When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.

Gene Expression

Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
