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.

Question
Transcribed Image Text:The double-stranded DNA sequence for a bacteria is shown below and it's coding for a
hypothetical protein. The strand on top reads 5' to 3' left to right, while the strand on the bottom
reads 5' to 3' right to left. The nucleotides are numbered 1 to 100. REMINDER: For this
problem, transcription begins with and includes the red and underlined C/G (top strand/bottom
strand) base pair and RNA polymerase proceeds from left to right along the DNA.
