Answer:
The correct answer is option a. "Double-stranded regions of RNA typically take on an B-form right-handed helix".
Explanation:
Most of the native double-stranded DNA is on an B-form right-handed helix, following the structure proposed by Watson and Crick with about 10–10.5 base pairs per turn. However, double-stranded RNA does not follow this structure, and most regions have an A-form structure. The A-form right-handed helix have slightly more base pairs per turn, which makes it 20-25% shorter than B-DNA.
Answer:
<u>Basal cells</u>
Basal cells divide faster than needed to replenish the cells being shed, and with each division both of the two newly formed cells will often retain the capacity to divide, leading to an increased number of dividing cells.
Im srry if its wrong :(
One such example of flowers which smells like rotten meat are- Carrion flowers or corpse flowers. The pollinators for these flowers are mostly <u>beetles and flies</u>. The mode of pollen transfer is by trapping these insects and allowing the pollens to stick to the body of the insects, before they leave the flower. But this happens in some of the species only.
<u>Answer: Beetles and flies</u>.
