Answer:
RNA polymerase moves along the template strand in a 3'-to-5' direction.
Explanation:
RNA polymerase is an enzyme involved in the synthesis of an RNA molecule from a DNA molecule. The process of synthesis of an RNA molecule is known as transcription which takes place in the nucleus of eukaryotes.
The DNA strand which is transcribed into the RNA molecule is known as template DNA and run from the 3'to 5' end.
The RNA polymerase enzyme binds to the promoter region which initiates the reaction. The RNA polymerase enzyme forms the RNA molecule in 5'to 3' direction by adding new nucleotide at 3'end, therefore, it has to move on the template strand with 3' to 5' direction.
Thus, the selected option is correct,
Stabilizing selection is the correct answer. It decrease the amount of biodiversity on earth.
Answer:
Help new plants sprout :)
Explanation:
Forest fires burn away leaf and dead plant litter. It can also burn away invasive species or any diseased plants. Then, nutrients are returned to the soil which helps new plants sprout and thrive. Hope this helped !!
Answer:
See the answer below
Explanation:
A DNase is also known as deoxyribonuclease and it is an enzyme that catalyzes the degradation of deoxyribonucleic acid by cleaving the phosphodiester linkage in their structures. Thus,<em> if the RNA is treated with a DNase before the plants are exposed to it, it will not make any difference. The plants will develop the same types of lesions as if they have been exposed to the mosaic virus.</em>
Unlike DNase, RNase is a ribonuclease, an enzyme that is capable of carrying out catalytic degradation of ribonucleic acids. <em>This means that if the RNA is treated with RNase before the plants are made to be exposed to it, they will not develop the lesions because the RNA would have been degraded by the enzyme.</em>
A protease is an enzyme that degrades the structure of proteins. <em>Treating a RNA with protease will thus have no effect on the structure of the RNA. Exposing the plants to the protease-treated RNA will make no difference. The plants will still come down with the lesions as if they have been exposed to the virus. </em>
Answer:
So if the size of the pore is small then the rate of the diffusion will be very slow as the molecules will move from high concentration to low concentration in very slow rate.
