The most important type of RNA in cells is:
Correct answer: C. mRNA
- A. rRNA
- B. tRNA
- C. mRNA
- D. cRNA
Explanation
The most important type of RNA in cells is messenger RNA (mRNA). mRNA is essential because it carries the genetic code from the DNA in the nucleus to the ribosomes in the cytoplasm. This code is presented in the form of codons-three-nucleotide sequences-each specifying a particular amino acid. During protein synthesis, mRNA serves as a template for assembling a sequence of amino acids to form a protein. While ribosomal RNA (rRNA) and transfer RNA (tRNA) are also crucial for protein synthesis, rRNA as part of the ribosome's structure and tRNA in transporting amino acids, they do not convey genetic information like mRNA does. cRNA is not a standard type of RNA involved in cellular processes.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
