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.
which functions do the two telomere-associated
complexes, telomerase and shelterin, fulfill at chromosome ends?
The telomeres represent the ends of all eukaryotic chromosomes and they serve an important biological role in maintaining genomic integrity by preventing degradation and end fusions. Various protein complexes are associated with the telomeres either to protect them from DNA damage machinery or to maintain telomere length homeostasis.
