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.
Describe the steps of
Introduction:
- DNA replication means replicating or producing two same replicas of DNA from one parental DNA. It occurs both in prokaryotes and eukaryotes
- In prokaryotes the replication starts from a single origin(ori c) and has multiple round of replication.
- In eukaryotes there is multiple origin and single round of replication.
- It always takes place in 5' to 3' direction.
- It requires many enzymes to initiate , process and completion.
