Segment of DNA SGCTAACCTGATCGCCGGTATT 3'CGATTGGACTAGCGGCCATAAS 3' 1. Transcribe and translate the above segment of DNA. 2. A point mutation occurs in the above segment of DNA. Nucleotide #14 is substituted by a nucleotide containing cytosine. Determine the sequence o amino acids in the polypeptide chain. Show all your work. Is there any vi: effect of the mutation, that is, is it a silent mutation? 3. The DNA segment above is mutated at nucleotide #12. The new nucleotide contains adenine. Transcríbe and translate the new DNA segment. What en if any, does this have on the protein sequence? Explain
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.
