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 the original F+ cell, newly synthesized _________ replaces the single strand transferred to the previously F− cell.
F+ strains are the bacterial cells that have an F factor. F factor is the fertility plasmid that confers a bacterial cell as a donor for the DNA during the process of conjugation. The strains that lack F factor are called F- strains and serve as recipient of the DNA during the process of conjugation.
Mating between F+ and F- strains includes the introduction of a cut in one strand of the F factor by an endonuclease. This F factor then moves to the F- strain via conjugation tube. DNA replication occurs on both single strands. The process of DNA replication restores the double-stranded DNA of the F factor.
