Which one of the following lists the steps involved in the production of new proteins in the appropriate order and correctly describes each step?

Answer 1

The below equation will show you that how proteins froms.

a) DNA -------> b) RNA --------> c) Protein



In the step a. :- The DNA is transcribed by RNA polymerase and forms RNA or mRNA or Messanger RNA

In step b. :- This mRNA is then translated by Ribosome and forms the protein by attaching the specific amino acid in a chain fashion with the help of tRNA ( This tRNA fetches the specific amino acid to the ribosome from the cytoplasm).


In step c.:- The protein is ready but not for still it is meaning less for a cell so it undergoes in some modifications, thats we call as Protein modification.

Answer 2

Protein synthesis requires DNA codes (genes) that use RNA through transcription to make proteins in translation.

In transcription RNA will be made.

RNA will be used to code for the proteins and translation.

This process is to create RNA and uses the enzyme RNA polymerase.

The process of the mRNA (messenger RNA) produced through transcription being altered in 2 ways before it leaves through the nuclear pores. One way is adding's to the 5 prime end and a 3 prime end.

Translation is the process of mRNA being used to make proteins in the ribosome. mRNA will attach to the ribosome which will assemble amino acids into a polypeptide chain. This process includes 2 steps; initiation and elongation.

Answer 3

DNA transfers information to mRNA...mRNA travels from nucleus to cytoplasm... ribosomes translate mRNA into proteins
