Messenger RNA (mRNA) is a carrier of information- specifically, a single-stranded complement to a segment of DNA copied to produce a protein for some purpose that is sent to the ribosomes for translation into the needed protein.
Transcription: mRNA is copied from a DNA molecule. Translation: The mRNA molecule then attaches to ribosomes. tRNA carrying amino acids come and attach to Codons on the mRNA. The amino acids bond to form a chain and a protein is formed.
Transcription.
In cells, protein is produced in the ribosomes. The instructions for protein synthesis are found in the DNA, which is copied onto mRNA. This mRNA then carries these instructions to the ribosomes where protein synthesis occurs.
The original DNA molecule is the template for the new DNA molecules.
DNA technically isn't copied but transcribed, i.e. copied into a different format, so we called the process transcription. The results of this process is that an mRNA molecule is created that heads out to the ribosomes to be translated into a protein.

The intermediate molecule formed between DNA and protein is mRNA (messenger RNA). The process in which the DNA sequence is copied to an RNA sequence is called transcription. The process in which the mRNA template is read to produce protein is called translation (protein synthesis)
Replication begins when an enzyme called DNA helicase attaches to a DNA molecule, moves along the molecule, and "unzips" the two strands of DNA.
RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. As complex molecule composed of protein subunits, RNA polymerase controls the process of transcription, during which the information stored in a molecule of DNA is copied into a new molecule of messenger RNA.
How can a section of text in a Notepad document be highlighted to be copied to another location within the document
mRNA by transcription
A gene is a segment of DNA sequence which can fold in any orientation and hence will code for a particular protein. DNA molecule is a double helix structure formed by complementary base pairing of nucleotides. Proteins are formed by particular t-RNA and are synthesized in ribosomes. Proteins are required for various metabolic activities occurring in the body. A simpler way to say the same thing is: A gene is a section of a DNA molecule that contains the information to code for one specific protein.
When protein synthesis must take place, the code to make the protein is on the DNA in the nucleus but the protein is made at a ribosomal site in the cytoplasm. The code is copied from the DNA by a special molecule called messenger RNA (mRNA) which leaves the nucleus through a pore to go to the ribosome.
Simply, it is protein synthesis. Specifically, it is called 'translation'. 'Transcription' happens at the DNA molecule, as it is copied by mRNA, then this code is 'translated' by tRNA (reversal of mRNA anticodon) and the tRNA molecules go out to get the corresponding amino acid to add to the growing protein molecule in the ribosome.
