53. The DNA sequence from which a functional non-coding RNA is transcribed is often called an RNA gene. a. True b. False 54. Exons are a. A segment of DNA or RNA molecule containing coding sequences b. A segment of DNA or RNA molecule which does not code for proteins and interrupts gene sequences c. Neither of these 55. Eukaryotic transcription units are classified as a. Simple b. Complex C. Intergenic d. Extragenic e. Both a and b
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.
