This particular area of genetics can be quite complex. So basically in DNA their is adenine, cytosine, guanine, thymine. So, then there is another step to this: Adenine links with Thymine (A is to T), and Cytosine pairs up with Guanine (C is to G). This is known as base pairing. However, when translating DNA to RNA their is a catch, there is no thymine in RNA. Instead there is Uracil. SO in RNA it would be like so: A is to U and C is to G. So when transcribing DNA to mRNA it would be like this. I will give an example: DNA: TGA GTC AAT GGC. However with RNA it would be like this, using the same example I just showed you: ACU CAG UUA CCG. Do you see I it now? Basically when transcribing to RNA you use the opposite of all of the original copy except use Uracil instead of Thmine.

Relatively uniform loss of color in leaves, occurring first on the older ones, is usually a sign of deficiency of which of the f

Mashcka [7]

Answer: D. magnesium

Explanation:

Chlorosis is a condition in which the leaves of the green plants do not have enough nutrients so as to synthesize the chlorophyll to keep the leaves green. Thus the leaves loose their color. The loss of chlorophyll from the older leaves is the characteristic feature of magnesium deficiency. It happens when the soil in which the plants are growing lacks magnesium.
