Functions of RNA:
RNA, or ribonucleic acid, plays a crucial role in various cellular processes. It is involved in genetic information transfer, protein synthesis, and is a constituent component of ribosomes.

1. RNA as a carrier of genetic information from DNA to ribosomes synthesizing polypeptides:
One of the primary functions of RNA is to act as an intermediary between DNA and protein synthesis. This process involves three types of RNA: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

- mRNA: mRNA carries the genetic information encoded in DNA to the ribosomes, where it serves as a template for protein synthesis. It carries the instructions for the order of amino acids in a polypeptide chain.

- tRNA: tRNA plays a crucial role in protein synthesis by transporting amino acids to the ribosomes. It binds to specific amino acids and carries them to the ribosome, where they are added to the growing polypeptide chain according to the instructions provided by mRNA.

- rRNA: rRNA is a major component of ribosomes, which are the cellular organelles responsible for protein synthesis. rRNA combines with proteins to form ribosomes, providing the structural framework for protein synthesis.

2. RNA carrying amino acids to ribosomes:
As mentioned above, tRNA molecules are responsible for carrying amino acids to the ribosomes during protein synthesis. Each tRNA molecule has a specific anticodon sequence that matches with the codon on mRNA, ensuring the correct amino acid is added to the growing polypeptide chain.

3. RNA as a constituent component of ribosomes:
rRNA, along with proteins, forms the structure of ribosomes. Ribosomes consist of a large subunit and a small subunit, both of which contain rRNA molecules. These ribosomal subunits work together to catalyze the process of protein synthesis.

Conclusion:
In summary, RNA serves multiple functions in the cell, including carrying genetic information from DNA to ribosomes, transporting amino acids to ribosomes, and being a constituent component of ribosomes. These functions are essential for the synthesis of proteins, which are vital for various cellular processes and functions.

Read the following passage to answer the following questions:Proteins are polypeptide chains made up of amino acids. There are 20 types of amino acids joined together by peptide bond between amino and carboxylic group. There are two kinds of amino acids, Essential amino acids and Non-essential amino acids. The Primary structure of protein is the linear sequence of amino acids in a polypeptide chain. The first amino acid of sequence is called N-terminal amino acids and last amino acid of peptide chain is called C-terminal amino acids. The secondary structure proteins forms helix. There are three types of secondary structure: a helix, P pleated and collagen helix. In tertiary structure long protein chain is folded upon itself like a hollow woollen ball to give three-dimensional view of protein. In quaternary structure, each polypeptide develops its own tertiary structure and function as subunit of protein.Q. The tertiary structure of a protein contains
