If a mutation occurs in a coding region a. it will cause a change or changes in the normal (wild type) amino acid sequence. b. the protein may not form correctly and as a result does not perform the intended function. c. the type of mutation can be a missense mutation if there is some or limited protein function. d. the type of mutation can be a nonsense mutation if there is no protein function. e. all of the above
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.
1. If a mutation occurs in a coding region
a. it will cause a change or changes in the normal (wild type) amino acid sequence.
b. the protein may not form correctly and as a result does not perform the intended function.
c. the type of mutation can be a missense mutation if there is some or limited protein function.
d. the type of mutation can be a nonsense mutation if there is no protein function.
e. all of the above
2. If a mutation occurs in a non-coding region:
a. it will cause no change in the normal (wild type) amino acid sequence.
b. the protein is unaffected and still functions correctly.
c. the type of mutation is called a silent mutation.
d. the protein may not form correctly and as a result does not perform the intended function.
e. all of the above
