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.
Below is a portion of an exon from a gene that encodes protein X in the genome of the plant Arabidopsis.
Wildtype DNA
3’ TTC AAT GCT CCG AAT ACC 5’ template strand
5’ AAG TTA CGA GGC TTA TGG 3’ non-template strand
A new strain (Strain B) of Arabidopsis is identified with the same region of the gene coding for protein X:
3’ TTC AAT GCT CCC AAT ACC 5’ template strand
5’ AAG TTA CGA GGG TTA TGG 3’ non-template strand
Compare the two DNA sequences and look for any differences. Based on what you find
There is no mutation in Strain B compared to Strain A.
After the point of the mutation, all the amino acids encoded by the Strain B template will be different than the Strain A protein X.
Protein X made from the Strain B template will be much shorter than protein X made from the Strain A template
Protein X from Strain B will have one amino acid difference that would not affect protein function.
There is a mutation but there will not be any difference in the primary sequence of protein X encoded in Strain B compared to Strain A.
Protein X from Strain B will have one amino acid difference compared to Strain A that may affect protein function.
