59 Walter Gilbert coined the term ( ) for an intervening sequence that is removed during the conversion of a primary transcript to a mature RNA. 60 RNA polymerase II requires the assistance of general ________________ to transcribe naked DNA from specific transcription sites. A. enhancers b. repressors c. promoters D. transcription factors
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.
