In a sample of double-stranded DNA, if the nitrogenous base guanine is 19%, then the nitrogenous base adenine will be 31%
Explanation:
In a double-stranded DNA, the four nitrogenous bases bind and pair together. The purine bases guanine (G) and adenine (A) pair with pyramidine bases cytosine (C) and thymine (T) respectively. The pairing will be between G-C and A-T bases.
According to Chargaff’s Rule, the percentage of each nitrogenous base will be equal in a pair. So the percentage of G will be equal to percentage of C and the percentage of A will be equal to percentage of T.
So if the guanine percentage is 19%, then applying Chargaff’s rule, cytosine will also be 19%
The remaining 68% will be shared with the adenine and thymine pair, of which adenine will be of 31% according to Chargaff’s rule.
Most of the flowering plants are pollinated by the insects and flies. These flies and insects are attracted to them because of their colorful petals or good smell.
But Skunk Cabbage has no colorful petals nor do they smell good like other flowering plants. They emit an odor of the rotten flesh to attract flies mostly carrion flies but also mosquitoes and bees etc.
The stamen and style grow out to be pollinated with other pollen attached to the carrion flies.
I believe the answer is a.
Is that cancel is to cross out something with lines etc while suspend is to halt something temporarily
Yes, true. Thrush can be a sign of AIDS.
