. The following represents a DNA strand in the process of replication. The bottom sequence is that of the DNA strand with polarity indicated and the top sequence represents the RNA primer. GGGGCCUUG 5′ TATAACCCCGGAACACTATAC 3′ Which of the following will be the first DNA nucleotide added to the primer? a. C b. G c. A d. T
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.
