A RNA copy of a DNA gene <--- Gradpoint/NovaNet
Messenger RNA (mRNA) is a form of RNA that codes for amino acids.
During transcription a sequence of mRNA is made from a corresponding sequence of DNA. In a eukaryote, the mRNA is then processed and sent outside the nucleus to be translated by a ribosome in the cytoplasm.
As for a prokaryote (which has no nucleus), the mRNA is already in the cytoplasm and just needs to be translated by a ribosome also in the prokaryote's cytoplasm.
mRNA, or messenger RNA, is a molecule that carries genetic information from the DNA in the cell nucleus to the ribosomes in the cytoplasm. These ribosomes then use the information from the mRNA to create proteins through a process called translation. This process is crucial for gene expression and protein synthesis in cells.

What is the function of the cap and tail on eukaryotic mRNA?
The cap and tail on eukaryotic mRNA play important roles in mRNA stability and translation. The 5' cap protects the mRNA from degradation and helps in the initiation of translation. The poly(A) tail at the 3' end of mRNA also plays a role in mRNA stability and regulation of translation.
The 5' cap of mRNA is important for what?
The 5' cap of mRNA is important for several reasons: it protects the mRNA from degradation by exonucleases, helps in the recognition and binding of the mRNA by the ribosome for translation, and is essential for efficient splicing of introns.
Where is the process of making mRNA from DNA called?
The process of making mRNA from DNA is called transcription. It takes place in the cell nucleus and involves the synthesis of mRNA using one strand of DNA as a template.
When tRNA copies mRNA it is called what?
When tRNA copies mRNA, it is called translation. During translation, tRNA molecules carry specific amino acids to the ribosome, where they align with the complementary codons on the mRNA to synthesize a protein.
A DNA strand with the base sequence tgacgca codes for a strand of mrna the mrna will have what base sequence?
The mRNA sequence generated from the DNA strand tgacgca would be acugcgu. This is because mRNA is complementary to the DNA template strand, so DNA base T pairs with mRNA base A, DNA base G pairs with mRNA base C, DNA base A pairs with mRNA base U, and DNA base C pairs with mRNA base G.
What carry instructions for making proteins?
mRNA

What is the scientific term for writing the mRNA message in a cell?
Transcription is the process by which the mRNA message is produced in a cell. During transcription, the DNA sequence is copied into mRNA by RNA polymerase.
What is the order of how a cell changes DNA messages to protein?
DNA -> transcription -> pre-mRNA -> mRNA processing -> mRNA -> translation -> protein
The 5' cap of mRNA is important for what?
The 5' cap of mRNA is important for several reasons: it protects the mRNA from degradation by exonucleases, helps in the recognition and binding of the mRNA by the ribosome for translation, and is essential for efficient splicing of introns.
What is the relationship between chromosome mRNA and proteins?
The mRNA is transcribed into proteins
What base does mRNA have that DNA does not?
Uracil replaces Thymine as a base in mRNA.
What cells parts does mRNA attach?
The mRNA attaches itself to a ribosome.
What is the stop codon in most molecules of mRNA?
stop codon on mRNA
Are codons found in mRNA or tRNA?
mRNA is made up of anticodons
Does translation involve the formation of mRNA?
No, transcription involves the formation of mRNA.
Where does mRNA travele to in a cell?
mRNA travels to the ribosomes in the cytoplasm of a cell. Ribosomes are the cellular machinery responsible for translating the mRNA into proteins.
