4. Within this double-stranded segment of DNA, there is a protein-coding region for a gene. 3'-AATATGACGTCAGTAGA-5' CODING STRAND ||| || || | || || || | || 5'-TTATACTGCAGTCA TCT-3' a. Identify on which strand the gene begins. Draw a box around the start codon. (1 pt) b. Which strand will RNA polymerase follow when it transcribes the gene? (.5 pts) c. In what direction will it transcribe? Draw an arrow above or below the DNA strands to indicate. (0.5 pts) d. Write the RNA sequence that would be transcribed below. (1 pt)
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.
