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.
Answer:
I agree
Explanation:
In the first graph, the DNA is split in the way that it splits Mitosis, and in graph 2 it splits the way it does during Meiosis.
Common Examples of Diffusion. You can smell perfume because it diffuses into the air and makes its way into your nose. A teabag placed in a cup of hot water will diffuse into the water. Placing food coloring in a liquid will diffuse the color.
