Blank - is the process of the messenger rna molecule copying the genetic code from the dna molecule in the nucleus.

The most appropriate word to fill in the blank is: Transcription.

Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace (modify or edit) and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacteria, animals, plants, etc., in order to correct a genetic disorder and to improve on their physical and chemical conditions.

Transcription can be defined as a process which typically involves re-writing the information contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

In conclusion, Transcription is the process of the messenger Ribonucleic Acid (RNA) molecule copying the genetic code from the Deoxyribonucleic Acid (DNA) molecule in the nucleus.

Messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes). The molecule that would eventually become known as mRNA was first described in 1956 by scientists Elliot Volkin and Lazarus Astrachan.
