Proteins are biomolecules, which make up different substances and play a crucial role in the replication, digestion, and synthesis of certain molecules.
Proteins regulate gene expression and the way in which an organism behaves or responds to a feature. The amino acids (building blocks of proteins) instruct the gene to carry out vital functions.
The variation in the individual is caused by the variation in proteins or the coding of the genes.
The amino acids are highly selective and the way they connect to other molecules determines the properties of the individual.
Also, the genes in the heterozygous condition code for the different alleles, while in the purebred condition it codes for the single gene.
Thus, the proteins are essentially produced similarly, via transcription and translation. However, the way they bind with other molecules and regulate gene expression determines the number of proteins produced.
