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.

- Bacteriophage λ, after infecting a cell, can integrateinto the chromosome of the cell if the repressor protein, cI, binds to and shuts down phage transcriptionimmediately. (A strain containing a bacteriophageDNA integrated into the chromosome is called a lysogen.) The alternative fate is the production of manymore viruses and lysis of the cell. In a mating, a donor strain that is a lysogen was crossed with a lysogenic recipient cell, and no phages were produced.However, when the lysogen donor strain transferredits DNA to a nonlysogenic recipient cell, the recipientcell burst, releasing a new generation of phages. a. Why did the mating with a nonlysogenic recipientresult in phage growth and release, but the infectionof a lysogenic recipient did not?When a temperate phage infects a bacteria cell it O immediately undergoes the temperate lifecycle. O immediately integrates its genome into the host cell genome; when conditions are harsh, the phage excises out of the host chromosome and undergoes the lytic lifecycle. O immediately undergoes the lytic lifecycle. O can either immediately undergo the lytic lifecycle or immediately undergo the lysogenic lifecycle, and it usually undergoes the lytic lifecycle.The protein of T2 bacteriophage is labeled with 35S and the DNA with 32p. Where would one detect most of the 32p if the T2 bacteriophage were allowed to infect the bacteria? O on the phage coat surrounding the T2 bacteriophage on the membrane of the infected bacteria O inside the T2 bacteriophage capsid O inside the infected bacteria O The 32P would be equally distributed within the T2 bacteriophage and infected bacteria
