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.
Semiconservative replication of DNA means that:
| a. |
both daughter duplexes will be entirely new and the parental duplex will be degraded |
|
| b. |
each daughter duplex will have one of the original parental strands and one new strand |
|
| c. |
each strand of the daughter duplexes will have parts of the parental strand and parts of the new strand |
|
| d. |
one daughter duplex will be entirely new and the other will have both original parental strands |
