Answer:
What does GGTCAATGCCATAAG into mRNA mean?
Explanation:
Answer:
The correct answer is- Histone
Explanation:
DNA is approximately 2.2 m long thread which has to be adjusted in a microscopic nucleus so DNA must be in a supercoiled form to be present in the nucleus and this supercoiling of DNA is done on histone protein.
Histone protein is a positively charged protein that is made up of eight proteins so it is called histone octamer. Each histone has 2 copies of each protein that is H2A, H2B, H3, and H4.
DNA is negatively charged and histone protein is positively charged therefore DNA wraps around histone protein which causes the packaging of DNA. So the correct answer is histone protein.
Plant Root and Shoot System. Plants have two Organ Systems: the shoot system and the root system. Stems have many jobs, including supporting the plant; acting like the plant's plumbing system, conducting water and nutrients from the roots and food in the form of sugar (glucose) made in the leaves to other plant parts.
1. Enzyme interacts with substrate
.
2. Enzyme may undergo a conformational change to capture the substrate ("induced fit" model)
3. Enzyme-substrate complex may undergo several changes to form the product(s).
4. The product(s) are released
.
5. The enzyme returns to its original form. It is then ready to do the cycle all over again.
