Answer:
They bind to an allosteric site which induces a conformational change that increases the affinity of the enzyme's active site for its substrate. This increases the reaction rate.
Through Polymerization larger molecules are formed.
Answer:
Option C
Explanation:
For chagarff's rule, it clearly states that DNA from any cell of any organisms be it prokaryotes or eukaryotes should have the basic 1 (purine): 1 (pyrimidine) ratio. Particularly, amount of adenine should be equal to thymine, and guanine equal to cytosine. This is in particular reference to organisms that have double stranded DNA.
The correct sequence is sources emit greenhouse gases; global temperatures rise; snow and ice melt; and sea levels rise. The natural and man made sources emit greenhouse gases that are responsible for the greenhouse effect. The increase in the Earth's temperature due to these gases absorbing more heat from the sun caused climate change like melting of snow and ice which contributes to the rising sea levels.
<u>Answer</u>:
Actions happens after transcription ends is "An mRNA molecule leaves the nucleus of the cell."
<u>Explanation</u>:
Transcription is the process of formation of mRNA from DNA. DNA is the genetic material which carries all the information for the formation of mRNA and then protein. Transcription occurs in nucleus, but as soon as the mRNA is formed it unwinds from the template DNA stand and moves into the cytoplasm for the next process i.e. translation. Translation occurs nearer to the ribosomes, it is the formation of protein from mRNA strand. combinedly transcription and translation are referred as the central dogma of the molecular biology.
