Question

The information contained within a gene is not directly copied into which of the following chemical forms?

Answer 1

The information contained within the gene is copied into a new molecule by the process of transcription. Transcription is a process by which the information from one strand of DNA is copied into a new molecule called messenger RNA or mRNA. Even though mRNA contains the same information it is not the exact copy of the DNA segment. Protein molecules include DNA and RNA and the genetic information is copied into the protein molecules by the process of transcription and translation. Transcription is a process by which the information coded in DNA is transferred to RNA, where as translation is a process where mRNA provides information for the Ribosome the type of amino acid to link with. As amino acids are made up of proteins there will be transfer of information contained in a gene to be transferred to protein. Whereas the function of tRNA is to carry amino acids to ribosome during the transcription hence it does not carry any genetic information where as rRNA combines with the set of proteins to form ribosomes. These rRNA molecule moves along with the mRNA molecule but does not carry any genetic information.

Therefore the answer is d
