Which of the following typos of RNA carries the information for the syrithasis of protoins?

Options

A. mRNA
B. tRNA
C. rRNA
D. sRNA

Answer

To determine which type of RNA carries the information for the synthesis of proteins, we can analyze the different types of RNA mentioned in the question:

1. **mRNA (messenger RNA)**: This type of RNA is responsible for carrying the genetic information from DNA to the ribosome, where proteins are synthesized. It contains the coding sequence that dictates the amino acid sequence of the protein.

2. **tRNA (transfer RNA)**: This type of RNA does not carry genetic information. Instead, it transports specific amino acids to the ribosome during protein synthesis, matching them to the codons on the mRNA.

3. **rRNA (ribosomal RNA)**: This type of RNA is a structural component of ribosomes. While it plays a crucial role in the protein synthesis process, it does not carry the genetic information itself.

4. **sRNA (small nuclear RNA)**: This type of RNA is involved in the splicing of pre-mRNA and other regulatory functions but does not carry information for protein synthesis.

Based on the analysis, the type of RNA that carries the information for the synthesis of proteins is **mRNA**.

**Final Answer**: mRNA
