Why do mutations in genes affect traits?

Answer 1

The affected genes by mutations changed the structure of enzymes, ultimately which affect the expression of particular trait/s.

Thank you, Dr. B K Mishra, India. The sequence of genes, or DNA structures, determines the sequence of amino acids in primary proteins, which in turn form enzymes. Enzymes are biocatalysts that aid in the expression of traits in an organism by catalyzing the chemical process associated with that trait. Modified biocatalysts function differently and impact the expression of normal traits.

Mutations in genes affect traits because they can alter the sequence of nucleotides in the DNA, which in turn can lead to changes in the structure and function of proteins encoded by those genes. Since proteins are involved in various cellular processes and functions, any changes in their structure can result in differences in the traits expressed by an organism.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
