consist of either one or two long chains of repeating units called nucleotides. DNA and RNA are the two main types.
elena-14-01-66 [18.8K]

Answer:

In case of both DNA and RNA, in general it is the nucleotides.

Nucleotides basically consists of three parts. The sugar(deoxyribose in DNA and ribose in RNA, both of which are pentose sugars), nitrogenous base and a phosphoric acid group.

The only component that varies in the nitrogenous base. There are five different types.

1.Adenine(A)

2.Guanine(G)

3.Cytosine(C)

4.Thymine(T)

5.Uracil(U)

1 and 2 are known as purines.

3, 4 and 5 are known as pyrimidines.

In DNA, A base pairs with T by means of a double hydrogen bond and G pairs with C by means of a triple hydrogen bond.

In RNA, A base pairs with U by means of a double hydrogen bond and G pairs with C by means of a triple hydrogen bond.

If DNA can’t leave the nucleus, how do you think the DNA instructions get to the ribosomes in the cytoplasm?
koban [17]

Instructions in the DNA are first transcribed to RNA and the RNA is transported to the ribosome in the cytoplasm.

<h3>Transcription</h3>

Transcription is a process whereby the genetic instructions in the DNA of organisms are transcribed to RNA in the nucleus.

After transcription, the RNA which now carries the genetic codes is transported to the cytoplasm where it gets attached to the ribosome before the genetic codes are translated to their respective amino acids.
