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.
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.
Yes, cDNA is complementary to mRNA.
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.
mRNA is transcribed in the 5' to 3' direction.
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.

Yes, cDNA is complementary to mRNA.
The creation of mRNA is called transcription. mRNA is being transcribed from the DNA template.
DNA -> transcription -> pre-mRNA -> mRNA processing -> mRNA -> translation -> protein
No, transcription involves the formation of mRNA.
The mRNA is transcribed into proteins
The mRNA attaches itself to a ribosome.
mRNA is made up of anticodons

Uracil replaces Thymine as a base in mRNA.
mRNA is transcribed in the 5' to 3' direction.
