Homeotic genes generally control dosage compensation. the formation of a specific body part. DNA methylation. hormone synthesis. X chromosome inactivation. The conversion of solar energy to chemical energy is known as photosynthesis. catabolism. metabolism. chemosynthesis. anabolism. Transcription factors bind directly to DNA. final proteins. RNA.
A) That homeotic genes are selectively expressed over developmental time. B) That a homeobox containing gene has to be a developmental regulator. C) That homeoboxes cannot be expressed in non-homeotic genes. D) That all organisms must have homeotic genes. E) That all organisms must have homeobox containing genes.
In Drosophila, expression of the segmentation genes activates the homeotic genes. Expression of the homeotic genes, in turn, determines which adult structures-including antennae, legs, and wings- will form in each of the adult fly's 14 body segments. Part A Two clusters of homeotic genes work together to specify body segment identity during ...
Question: homeotic genes A) are responsible for patterning during plantdevelopment. B) encode transcription factors that control the expressionof genes responsible for specific anatomical structures. C) are found only in Drosophila and other arthropods. D) encode proteins that form anatomical structures inthe fly.
Find out the answers to nine questions about homeotic genes and proteins in Drosophila and mouse development. Learn the concepts and mechanisms of Hox gene expression, regulation and function from an expert solution.
Question: Homeotic genes are important in evolution because two of these are correct. they are master genes that control numerous other genes. they control the body plan and development of organisms. they show very little variation among organisms. they evolve in a gradual step-by-step fashion.The half-life of carbon-14, a radioactive isotope of carbon, is 5730 years.
Question: As with all multicellular organisms, homeotic genes in plants control morphogenesis (how the tissues and organs of the plant are arranged). In maize plants, the homeotic gene KNOTTED1 (abbreviated KN1) helps maintain the indeterminate state of shoot apical meristems.
regulatory genes. structural genes. multiple genes. homeotic genes. Which of the following is a good definition of natural selection? Group of answer choices. survival of the fittest. nonrandom elimination of alleles. upward progression of a species. random changes in organisms’ genetic makeup
>Homeotic genes are expressed in a spatially and temporally defined manner because the regulatory regions of each homeotic gene have unique enhancers that respond to various zygotic patterning genes. >When multiple Hox proteins are expressed in a given segment, identity of the segment is dictated by the effect of more posteriorly expressed Hox ...
