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.

Question
Transcribed Image Text:QUESTION 37
You are studying a mutation in a gene that changes the codon from AUU to AAU. Will this mutation cause problems for the cell if the
protein is made?
(Hint: Use the final note sheet. Look at the codon chart and R groups.)
O Probably not, the amino acid changes but is similar in chemical properties to the original, so there will be no change to protein
structure.
O There is not enough information to know.
O No, this is a silent mutation (no amino acid change).
O Probably, the amino acid changes and the chemical properites are different, so structure and function will change.
