Messenger RNA (mRNA)

Written by Shubhi Khandelwal on Feb 26, 2020

Messenger RNA or mRNA is a type of RNA that is formed by transcription of DNA. It is single-stranded and sends signals from DNA to the ribosomes to synthesize proteins. This is why it is known as messenger RNA.

mRNA is a type of RNA that acts as a messenger of DNA to send information or message for the formation of proteins. mRNA is synthesized from the DNA by a process known as transcription. This takes place in the nucleus. The mRNA then moves to the cytoplasm towards the ribosomes and synthesize proteins by the process known as translation.

As mRNA is formed from DNA, it is complementary to one strand of the DNA. It is exactly the same as the other strand of the DNA except uracil is present in mRNA instead of thymine.

KEY TAKEAWAYS

Key Points

  • mRNA is formed from one strand of DNA by a process known as transcription.
  • It is complementary to the strand it is formed from and exactly the same as the other strand of the DNA except uracil is present in place of thymine in mRNA.
  • It helps in the formation of proteins by translation.

Key Terms

  • RNA: It is a type of nucleic acid that helps in the synthesis of proteins in the cells.
  • Transcription: It is the process of synthesis of mRNA from DNA.
