Answer:
It transcribes the DNA strand.
Explanation:
Transcription is the process of formation of RNA molecule from the complementary DNA strand with the help of RNA polymerase. Transcription process requires different enzymes and chemical factors.
RNA polymerase enzyme binds to the DNA template and adds nucleotides to the growing RNA strand, complementary to the template DNA strand. Hence, this enzyme synthesizes the RNA template from the DNA strand.
Thus, the correct answer is first option.
Answer:
The correct answer is to ADP and Pi is the most common mechanism for transferring free energy to drive endergonic reactions.
Explanation:
Many endergonic reactions(the free energy change of these reactions are highly positive) proceed in a thermodynamically unfavorable manner.
To make those reactions thermodynamically favorable,these reactions are coupled with hydrolysis of high energy compound such as hydrolysis of ATP to ADP and Pi.
As a result the free energy change of those reactions becomes negative which allow those reactions to proceed in a thermodynamically favorable manner.
Literally just had a test on this today :)
1 is correct.
2 is correct.
3: does true breeding like a purebred/homozygous/two of the same traits?
if so, all of the plants will show the dominant allele, so the answer is B
4 is correct.
5: 23 because when they combine, the chromosomes mix, and there are 46 in a regular cell. Half com from one parent, and half from the other, so the answer is A
6: homo is a prefix that means “same”, and zygous has something to do with genes, so the answer is homozygous
7 is correct
8 is correct
9: i have a strange felling that it is alleles, but DNA could also work, so I’m not quite sure on this one, sorry…
10: alleles are the different forms of a gene. Genes are transferred to you from your parents hereditarily. An allele for stem height would be T or t, but a gene would be TT, Tt, or tt.
I really hope this helps you! It was a hard unit for me, but i did get 100% on the test, and I’m sure you can too.
C:Primary cause i was asked this question and that is what the answer was
