List the types of RNA, and explain how the structure of RNA differs from the structure of DNA.
boyakko [2]

Answer:

   The types os RNA are: Messenger, ribosomal and transporter RNA and the difference between DNA and RNA are: DNA has deoxyribose as sugar, RNA has a ribose. The nitrogenous bases present in DNA are cytosine, guanine, adenine and thymine. In RNA, cytosine, guanine, adenine and uracil are found. DNA has two strands, but RNA is single stranded.

  In fact, the DNA has a genetica material like a genetical mensage and it must be translate and deciphered in proteins, many of which will act on the metabolic reactions of the cell. The message contained in DNA should initially be passed on to RNA molecules, which in turn will guide protein synthesis.

Explanation:

 Now talking about each types of RNA separately. The first one I am going to write about is RNA messenger. This type of RNA is of intermediate molecular weight and acts together with ribosomes in protein synthesis. The second one is ribossomal RNA. It is the largest molecular weight and major constituent of ribosome, an organoid related to protein synthesis in the cell. The last one is transporter RNA. It is the lightest of the three and tasked with transporting the amino acids that will be used in protein synthesis.
