Ribonucleic acid (RNA) is a polymer of nucleotides , which is directed by the DNA for the synthesis of proteins. It is made up of ribose sugar and nitrogenous bases, namely adenine, guanine, cytosine, and uracil. RNA is structurally similar to DNA but differs on the basis of sugar, strand, and nitrogen base.

Summary Introduction

Introduction: Ribonucleic acid (RNA) is a polymer of nucleotides, which is directed by the DNA for the synthesis of proteins. It is made up of ribose sugar and nitrogenous bases, namely adenine, guanine, cytosine, and uracil. RNA is structurally similar to DNA but differs on the basis of sugar, strand, and nitrogen base.

Expert Solution & Answer

Answer to Problem 1MC

Correct answer: Option b. “messenger RNA”.

Explanation of Solution

Reason for the correct answer:

Option b. is given as “messenger RNA”.

Messenger RNA (mRNA) functions as an information carrier from DNA in the nucleus to the ribosome in cytoplasm of the cell. This information is used by the cell to direct the synthesis of proteins. Group of three bases in mRNA is called codons that specify which amino acid will be incorporated into a protein.

Hence, option b. is correct.

Reasons for incorrect answers:

Option a. is given as “ribosomal RNA”.

Ribosomal RNA is responsible for the production of ribosomes at which polypeptide chains are formed during translation. Hence, option a. in incorrect.

Option c. is given as “transfer RNA”.

Transfer RNA transfers the amino acid to the ribosomal unit in translation process by which the information in mRNA is translated into protein molecules. Hence, option c. is incorrect.

Option d. is given as “noncoding RNA”.

Non-coding RNA is transcribed from DNA, but is not translated into proteins.

Hence, option d. is incorrect.

Hence, options a., c., and d. are incorrect.

Conclusion

Messenger RNA carries the genetic information from DNA to the cytoplasm which is then used for protein synthesis.
