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:g.
Is this a silent mutation (no change in amino acid sequence), missense mutation (one amino acid changed to a
different amino acid), or nonsense mutation (one amino acid changed to a stop codon)? Explain how you
know.

e. Give the sequence (and indicate the directionality) of the anti-codon on the tRNA that inserts the 2nd amino
acid into the newly made peptide.
f. Imagine that, in the process of DNA replication, the 39th base in the gene (with the *) was changed from A/T to
C/G. What would be the effect of this mutation on the produced peptide?
