"mRNA" is an abbreviation for Messenger RNA. It carries the genetic code for protein to the rRNA (ribosomal RNA) and enzymes in the ribosomes where tRNA (transfer RNA) carries amino acids which are matched to the mRNA to form protein.
DNA is the originating molecule containing the master copy of the code. This is copied to the mRNA first.
The differences between DNA and RNA are that 1) RNA has uracil in place of thymine and 2) RNA uses ribose instead of the 2-deoxyribose in DNA. There are both double stranded and single stranded DNA and RNA in nature so this is not a defining difference.
It depends on what sort of organism it is as to where these compounds are in the cell but the process is similar. In the eukaryotes, there is an extra step that takes place in the nucleus where the mRNA is first cut and spliced.

How is DNA replication affected by a lack of mRNA?
Not at all. mRNA is not involved in DNA replication as it is involved in transcription and translation.
DNA Transcription is the production of?
messenger RNA (mRNA)
A strand of mRNA has the bases guanine-adenine-uracil Which amino acid corresponds to these bases?
Asp
Which best describes how scientists found he human gene that makes insulin?
they worked backwards from mRNA to DNA Ap#x
Is the enzyme that allows replication to occur DNA polymerase or RNA polymerase?
DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.
What does reverse transcriptase use from DNA?
Reverse transcriptase use mRNA to form DNA. mRNA
How is mRNA differint from DNA?
The mRNA comes into the DNA when the DNA unzips. Then the mRNA attaches to one side of the DNA, copies it down, and leaves. Remember, AT CG
What is made in transcription?
mRNA is made. Messenger (Ribose Nucleic-Acid). mRNA is a single strand of RNA made from the template strand of DNA. The mRNA is a exact copy of the coding or sense strand of DNA. The only difference between the produced RNA and DNA is the DNA has deoxyribose as its backbone sugar, and all Thymines have are replaced with Uracil.
Where is the process of making mRNA from DNA called?
DNA to mRNA is transcription, whereas mRNA to tRNA is translation. The latter part is when proteins are made from ribosomes and instructions carried over by mRNA from the DNA.
Difference between sense and anti sense strands of DNA?
The sense strand has the same base sequence as mRNA with uracil instead of thymine. The antisense strand is transcribed.
How can you tell the difference between a DNA molecule undergoing transcription and being replicated?
If the DNA molecule is undergoing transcription, then mRNA nucleotides will be forming along the anti-sense strand of DNA. If the DNA molecule is undergoing replication, new DNA nucleotides will be forming along both original strands of DNA.
What is the order of how a cell changes DNA messages to protein?
DNA -> transcription -> pre-mRNA -> mRNA processing -> mRNA -> translation -> protein
What does transcriptase use to form DNA?
Reverse transcriptase use mRNA to form DNA. mRNA
What is the order of actions by rna polymerase?
Binds to DNA, makes mRNA from DNA, detaches
What is used to carry the genetic code from DNA to the ribosomes?
The mRNA carries the genetic code needed to make a protein to the ribosome from DNA via microtubules.
Carries the message of DNA to ribosomes?
mRNA (messenger RNA) carries the instructions for protein synthesis from the DNA to the ribosomes.
What is the process of forming RNA from DNA?
The process of forming mRNA from DNA is known as transcription.It is best to be specific when referring to RNA. There are three types of RNA: mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).Note that when transcribing mRNA from DNA, thymine (in DNA) is paired with adenine (in mRNA) and adenine (in DNA) is paired with uracil (in mRNA).
