what is messenger RNA?

Answer 1

mRNA (Messenger) RNA ) carries genes to be expressed as protiens from the DNA of the nucleous in Eukaryotes to ribosomes where they are translated into the peptide sequences of proteins. the mRNA is single stranded as mentioned here, but likes to condense into little gnarly shapes for the trip. It also has to be tagged so the cell knows where to send it and left with extra bases on the end so it doesn't get broken down before it gets to the ribosomes with its message.

In bacteria however one or many ribosomes attach to the RNA at one end and move along making protien (polypeptides) while it still being transcribed from the DNA at the other, so "messenger"
is a bit of a misnomer.

Answer 2

RNA = messenger ribonucleic acid

it's formed of one strand formed from DNA in active cells that secret proteins or enzymes it's produced as the DNA can't leave the nucleus but RNA can and it's produce and pass out the nucleus to help ribosomes to syntheses of proteins (enzymes)
RNA contain 4 types of bases in it's structure adenine uracil cytosine guanine
and it carry the code of the specific protein and characterized by poly A tail

Answer 3

Because the DNA in a cell's nucleus is double stranded, it is too large to leave the nucleus through the nuclear pores. Messenger RNA is a single-stranded copy of DNA produced inside the nucleus that is small enough to exit through the pores. Once it is out in the cytoplasm, MRNA is "translated" by ribosomes into the protiens the cell needs to function.

Answer 4

Messenger RNA (mRNA) is a single strand of RNA that transfers the instructions for building proteins from the DNA in the nucleus to a ribosome where the protein will be built.

The mRNA is "read" codon-by-codon. A codon has three bases (AUG, CCG, ...) that calls for a particular amino acid to be added to a growing chain of amino acids to form the protein. The amino acids are "delivered" by transfer RNA or tRNA that has the opposite matching set of bases or anticodon. So the codon AUG on mRNA matches the anticodon UAC on tRNA, and that tRNA delivers a specific amino acid.

Answer 5

Messenger Ribonucleic Acid (mRNA) is RNA that encodes and carries information from DNA during transcription to sites of protein synthesis to undergo translation in order to yield a gene product.

Answer 6

mRNA is what is made in the Cell Nucleus and transported outside into the Cytosol where Rybosomes are built around it and then a Polymer is made. DNA is like the original blueprint of the genetic code. mRNA is the first copy. It usually gets edited a bit before its sent out of the Nucleus. It is the mRNA that actually gets read by the Rybosomes, and then translated into the product coded by the gene.
