Question 11 Which polymerase is responsible for transcribing RNA from a single transcription unit, generating a large transcript that is then processed to yield three types of ribosomal RNA Question 11 options: RNA Polymerase I RNA Polymerase II RNA Polymerase III DNA Polymerase Question 12 RNA splicing requires recognition of which nucleotide sequences at the boundaries of transcribed exons and introns (splice junctions)? Question 12 options: GT–AG TG-CA CT-CG CpG Question 13 Following are the three consensus DNA sequences in introns of complex eukaryotes except: Question 13 options: Splice donor site Splice acceptor site Branch site Initiation site
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.
