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.
Which type of cell does not possess introns and extrons and produces polycystronic mRNA?
Prokaryotic cells do not possess introns and exons, and they produce polycistronic mRNA. This mRNA contains multiple coding sequences for different proteins in a single transcript, allowing for the production of several proteins from one gene.
What carry instructions for making proteins?
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 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.
Are codons found in mRNA or tRNA?
mRNA is made up of anticodons
