16. Which of the following describes what happens to the codons of a cell that is affected by sickle cell anemia? Codon GTG changes to GAG. The codon GAG, which codes for glutamic acid, changes to a stop codon. The mRNA codon contains two bases instead of three. A point mutation causes the amino acid valine to be formed, instead of the amino acid glutamic acid.

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 anoth…

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.
