A primary transcript (immature, non-processed) single-stranded RNA molecule has the following nucleotide composition: 30% A, 20% G, 24% C, and 26% U. What is the nucleotide composition of the double-stranded DNA molecule from which it was transcribed

The nucleotide composition of the double-stranded DNA molecule from which it was transcribed is 30% T, 20% C, 24% G, and 26% A.

Explanation: RNA is transcribed from DNA in the process of transcription. The single stranded RNA is complementary to the DNA template strand. In DNA base pairing, adenine pairs with thymine while guanine pairs with cytosine, this means that in a double-stranded DNA molecule, the total number of adenine is equal to the number of thymine while the total number of guanine is equal to the total number of cytosine.

In RNA, adenine pairs with thymine, guanine pairs with cytosine while uracil pairs with adenine. This means that the total number of thymine on the DNA template strand is equal to the total number of adenine on the RNA strand, the total number of guanine on the DNA template strand is equal to the total number of cytosine on the RNA strand, the total number of adenine on the DNA template strand is equal to the total number of uracil on the RNA strand while the total number of cytosine on the DNA template strand is equal to the total number of guanine on the RNA strand.

RNA strand = DNA strand

30% A = 30% T

20% G = 20% C

24% C = 24% G

26% U = 26% A

meiosis is the correct answer

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
