A gene contains the sequence CGCATACGGTAC that results in the amino acid sequence arg-ile-arg-tyr. A mutation in this gene removes the first G in the strand. What is true of this mutation's effect on the phenotype? 1.It will affect the phenotype because although most of the protein will be identical, the first amino acid will be different. 2.It will not affect the phenotype because the protein will be identical to the original protein. 3.It will affect the phenotype because all the amino acids past this point will be different from the original protein. 4.It will not affect the phenotype because only the first amino acid is different from the original protein.
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.
