A mutation in a gene in the fruit fly drosophila was found to affect eye color. the protein affected was found to be completely
normal in its molecular weight and amino acid sequence, although much less of the protein is made in mutant flies. the most likely reason for the change in levels of protein is that the mutation
<span>The mutation did not affect amino
acid sequence or the molecular weight (no evidence of amino acid substitution
or protein truncation). Therefore, the mutation is not likely within the coding
region of the gene. Most likely the
mutation is in the regulatory region of the gene such as the promoter region.
Such mutation would interfere with transcription initiation and hence decreases
the amount of mRNA and protein produced. </span>
The organisms that eat the primary consumers are called secondary consumers. Secondary consumers are generally meat-eaters—carnivores. The organisms that eat the secondary consumers are called tertiary consumers. These are carnivore-eating carnivores, like eagles or big fish.
