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.
In addition to variable sites, the strucutre of a tRNA includes
A. Three stem loops with an anticodon in the second loop; acceptor stem where amino acid attaches.
B. Accepter stem where the anticodon is located; 3 stem loops with the second loop where the amino acid will attach.
C. 3 stem loops with a codon in the second loop; acceptor stem where the amino acid attaches.
D. Acceptor stem where the codon is located; 3 stem loops with the second loop where the amino acid will attach
tRNA
tRNA or transfer RNA, sometimes referred as sRNA, is a adapter molecule which read the codon present in the mRNA and bring amino acids according to the codon. The main function of tRNA is to decode the mRNA and synthesize the polypeptide chain.
For each amino acids, there are specific tRNA. Not all the amino acids are in a polypeptide chain is incorporated by single tRNA but each amino acids had specific tRNA.
