Dioxin, produced as a by-product of various industrial chemical processes, is suspected of contributing to the development of ca
ncer and birth defects in animals and humans. It apparently acts by entering cells by simple diffusion and binding to proteins in the cytoplasm, then altering the pattern of gene expression. Which of the following are likely to be the cytoplasmic proteins to which dioxin binds?
The question is incomplete as it does not have the options which are:
growth factor receptors
DNA polymerase
transcription factors
enhancers
nucleosomes
Answer:
Transcription factors
Explanation:
The dioxin is an organic by-product formed from the chemical reaction of the organic compounds.
The dioxin is one of the causes of cancer in organisms and the can acts as teratogen during the development of the prenatal child.
The dioxin shows it affects by binding to specific receptors which can activate the transcription of genes and are thus called transcription factors. The dioxin binds these transcription factor called AH receptors and can cause cancer.
Thus, the Transcription factor is the correct answer.
The integumentary system, which includes the skin, protects the body and regulates temperature/homeostasis. It also eliminates small amounts of waste, but it does not aid in movement directly.
DNA is a self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
Pressure exerted by fluid in a cell that presses the cell membrane against the cell wall. Turgor is what makes living plant tissue rigid. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt.
