Question

How do m RNA, r RNA, and t RNA work together in translation to build up a protein?

Answer 1

Hint: Translation is the last step of central dogma (the process of conversion of DNA to protein). Proteins are formed in this step from the RNA.
RNA translation Protein.

Complete answer:
Let’s understand the types of RNA and its uses:
RNA or ribonucleic acid is the single-stranded product of transcription formed from DNA. Many types of RNA are known out of which there are three well-known RNA i.e. mRNA, rRNA, tRNA.

The m-RNA (messenger RNA) carries the genetic codes reading which the proteins are synthesized. Therefore m-RNA is also called the transcripts. Ribosomal RNA (rRNA) is an important part of an organelle called ribosomes which are responsible for protein synthesis. Transfer or t-RNA is also known as adaptor molecules responsible for decoding the m- RNA and bringing the appropriate amino acids to the ribosome.

Every amino acid is represented by a 3 bases codon and m-RNA contains four bases A, U, G, and C. These bases in various combinations form different codons that code for different amino acids. So m-RNA guides the order in which the amino acids should be added to form a polypeptide chain. The t-RNA has two arms one binds to the mRNA template while the other arm carries the appropriate amino acid according to the codon of mRNA and last the ribosomes help in the assembly of these amino acids and form the polypeptide chain thereby completing the protein synthesis or translation.

Note: In eukaryotes the m-RNA is made in the nucleus while the protein synthesis takes place in the cytoplasm as the r-RNA and t- RNA are present in the cytoplasm.
