Question

What is the composition of RNA
A) A+T = G+C
B) A+G= T+C
C) A+U=G+C
D) A+G=U+C

Answer 1

The main constituents of RNA are five-carbon sugar, a phosphate group, and a nitrogenous base. The Nitrogenous bases present in RNA are adenine, guanine, uracil, and cytosine.

Complete answer: RNA, ribonucleic acid is a single-stranded molecule made up of ribonucleotides attached by phosphodiester bonds. One ribonucleotide is made up of ribose sugar made up of 6 carbons, a phosphate group, and nitrogenous bases. Nitrogenous bases are of 4 types in RNA these are adenine, guanine, cytosine, and uracil. Adenine and guanine are purines and cytosine and uracil are pyrimidines. Adenine pairs with uracil and cytosine pairs with guanine which means adenine =uracil, and guanine = cytosine.
Hence option d) is correct A+G=U+C.

Additional Information:
DNA, deoxyribonucleic acid is made up of nucleotides which are the building blocks of DNA. A nucleotide is made up of deoxy-ribose sugar, a phosphate group, and nitrogenous bases namely adenine, guanine, thymine, and cytosine.RNA converts the information on DNA into proteins.RNA is formed after transcription of DNA and RNA produces proteins after translation.RNA has a single-stranded structure and is synthesized in the nucleus and is found in the cytoplasm. There are three types of RNA namely mRNA, messenger RNA, transfer RNA(tRNA), and ribosomal RNA (rRNA). It plays an important role in the coding, decoding, regulation, and expression of genes.

Note: RNA is made up of ribonucleotides which are in turn made up of sugar-phosphate and nitrogenous bases. Pyrimidine bases pair with purine bases because of which the paired bases are equal to each other. In the case of RNA adenine pairs with uracil and guanine pairs with cytosine.
