Answer

Verified

Hint:In the given question we have to observe that the two components are present in both the RNA and the DNA. Now we know that both of them have some differences. Now we have to find the one which is present in just one of the given. Now Uracil is present in RNA thus Thymine isn’t.
Complete step by step answer:
The given question basically asks about the compound which is absent from the structure of the RNA.
DNA stands for Deoxyribonucleic acid and RNA stands for Ribonucleic acid.

For the case, RNA is almost equivalent to DNA, only some changes are there. So they also share most of the constituents along with the basic structure.

Now in this question Guanine and the Adenine both are parts of both the DNA and the RNA.
Apart from that they also share the component called cytosine.

Now among the Uracil and Thymine one is found in DNA and one is found in RNA. They are the basic difference between the two.

Uracil is present in the RNA whereas in the DNA we see thymine instead of Uracil.
Thus thymine is absent from the RNA.
Hence the correct option is option B, Thymine.

Note: RNA performs many functions in an organism, such as coding, decoding, regulating, and expressing genes. About \[5\% \] of the weight of a human cell is RNA. Only about \[1\% \] of a cell consists of DNA. RNA is found in both the nucleus and cytoplasm of human cells.
