Eukaryotic messenger RNA can undergo post synthetic processing after transcription and before translation. One of the processing steps is splicing, where portions of the RNA are removed and the remaining RNA are joined together. Classify the statements regarding mRNA splicing as true or false. True statements False statements In splicing, intron sequences are removed from the mRNA in the form of lariats (loops) and are degraded. Splicing occurs while the mRNA is still in the nucleus. Splicing of mRNA does not involve any proteins. One mRNA can sometimes code for more than one protein by splicing at alternative sites. Splicing occurs while the mRNA is attached to the nucleosome.

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.
