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.
What else can I help you with?
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.
Is cDNA complementary to mRNA?
Yes, cDNA is complementary to mRNA.
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.
In which direction is mRNA transcribed?
mRNA is transcribed in the 5' to 3' direction.
How does mRNA get out of the nucleus and into the cytoplasm for protein synthesis?
mRNA is transported out of the nucleus through nuclear pores in a process called mRNA export. Once in the cytoplasm, the mRNA binds to ribosomes where protein synthesis occurs.
What carry instructions for making proteins?
mRNA
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.
Is cDNA complementary to mRNA?
Yes, cDNA is complementary to mRNA.
What is the scientific term for writing the mRNA message in a cell?
The creation of mRNA is called transcription. mRNA is being transcribed from the DNA template.
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.
Does translation involve the formation of mRNA?
No, transcription involves the formation of mRNA.
What is the relationship between chromosome mRNA and proteins?
The mRNA is transcribed into proteins
What cells parts does mRNA attach?
The mRNA attaches itself to a ribosome.
Are codons found in mRNA or tRNA?
mRNA is made up of anticodons
What is the stop codon in most molecules of mRNA?
stop codon on mRNA
What base does mRNA have that DNA does not?
Uracil replaces Thymine as a base in mRNA.
