1.1 What is the best description of a Ribosome? a. An enzyme that uses ribose to synthesize amino acids b. A protein/RNA complex that synthesizes protein c. A ribozyme that uses RNA as an enzyme to directly ligate free amino acids to tRNAs d. A multi-subunit protein complex that charges tRNA with amino acids 1.2 In RNA processing? A. Exons are added to the ends of mRNA for protection B. Intron sequences are removed before the mRNA is translated C. The RNA transcript that leaves the nucleus may be much longer than the original primary transcript D. All RNA transcripts will be processed and leave the nucleus.
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.
