Question
Which of the following statements is correct?RNA controls the synthesis of proteins.The sugar present in DNA is D-(-)-ribose.RNA has double stranded α-helix structure.DNA mainly occurs in the cytoplasm of the cell.
Solution
The correct statement is "RNA controls the synthesis of proteins."
Here's why:
-
"RNA controls the synthesis of proteins." - This is correct. In the process of protein synthesis, messenger RNA (mRNA) carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where it is used to assemble amino acids into proteins.
-
"The sugar present in DNA is D-(-)-ribose." - This is incorrect. The sugar present in DNA is deoxyribose, not ribose. Ribose is found in RNA.
-
"RNA has double stranded α-helix structure." - This is incorrect. RNA is typically single-stranded, while DNA has the double-stranded α-helix structure.
-
"DNA mainly occurs in the cytoplasm of the cell." - This is incorrect. DNA is mainly found in the nucleus of the cell, not the cytoplasm.
