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.
Answer:
b. the rate at which the mRNA is degraded.
Explanation:
DNA is transcribed into mRNA which then joins ribosomes present in the cytoplasm to serve as a template for protein synthesis. Regulation of gene expression occurs at several levels.
One such regulatory mechanism is the stability of mRNA and the rate of its degradation which in turn affects the availability of template for the process of protein synthesis and thereby keeps a check on the total amount of protein being formed in a cell.
For example, a very short life span of bacterial mRNA (few minutes) allows them to regulate the pattern of protein synthesis quickly in response to the changes in surroundings.
The answer to your question will be B. The higher our current rate of consumption, the less coal will be available in the future.
