Answer: a. encode transcription factors that control the expression of genes
Explanation:
Homeotic Genes - They encode transcription factors that determine the location at which specific structures develop. They give organs identity. Homeotic genes act as regulators of development and some mutations found in flies were instrumental in unraveling the macroevolution related mysteries.
Mutations in homeotic genes are often fatal in the early stages of development, however viable mutant flies with strange aberrations have been found, such as the discovery of Antennapedia mutants, in which paws are formed in place of antennae. Homeotic genes regulate the development of specific embryonic segments and are fundamental, among other functions, in determining the anteroposterior axis of metazoans. When we compare flies and humans, homeotic genes resemble both their nucleotide sequence and their relative position on chromosomes.
Granum is what the answer should be
Since there are no written choices, I could guess that prokaryotes are not reliable when it comes to diseases and other forms of ill-causing behavior of these microorganisms.
Scientists rely on prokaryotes to examine their structure and functions in order to come up with a good medicine. Some rely on prokaryotes to do the natural processes of decomposing and recycling matter throughout the earth's spheres.
