What is the role of mRNA and tRNA in the production of protein?

mRNA: Transcription copies the information stored in the nuclear DNA into complementary code in the messenger RNA (mRNA). The mRNA then leaves the nucleus and moves into the cytoplasm. Ribosomes attach to the mRNA and start to translate the information contained in the mRNA into a sequence of amino acids. Ribosomes are small molecular scale machines that crunch along the mRNA, reading it like a tape, and adding appropriate amino acids together to create proteins.
tRNA: The amino acids are recognised, captured, and brought to the ribosomes by transfer RNAs (tRNAs). Inside a ribosome, the newly arrived tRNA, bearing its amino acid, docks next to the tRNA molecule already inside the ribosome. The polypeptide chain is then attached to the newly delivered amino acid and so comes to hang from the incoming tRNA. The first (now liberated) tRNA then exits from the ribosome. The ribosome grinds along the mRNA and a space is created to accommodate a new incoming tRNA with its attached amino acid. This process is repeated each time an amino acid is added.

What role does the structure of RNA and DNA play in protein synthesis?
mRNA. tRNA,
What codes for a protein in a eukaryote?
The mRNA is coded by the tRNA to make a protein.
Which type of RNA makes protein?
1. mRNA - provides 'template' for protein 2. tRNA - carries amino acids 3. microRNA/siRNA - regulate protein production
What type of RNA is involved in translation?
ribosomal RNA and transfer RNA
What is the type of RNA that is converted to a protein during translation?
Messenger RNA (mRNA) is translated into polypeptides on ribosomes by transfer RNA (tRNA).
What role does the structure of RNA and DNA play in protein synthesis?
mRNA. tRNA,
What does tRNA have that mRNA does not have?
Protein Parts
What does trna does that mrna does not have?
Protein Parts
What carries the protein parts to the ribosome and the mRNA?
tRNA carries the protein parts to the ribosome and the mRNA.

1. mRNA - provides 'template' for protein 2. tRNA - carries amino acids 3. microRNA/siRNA - regulate protein production
A single stranded nucleic acid that plays a role in protein synthesis?
RNA. mRNA, tRNA, and rRNA all play parts.
What process do mrna Trna work together to complete?
mRNA and tRNA work together to complete the process of translation, which is the second step of protein synthesis, in which the genetic code on the mRNA is translated into a sequence of amino acids by the tRNA.

What happeneds in synthesis?
First, the DNA polymerase makes a copy of the DNA. The nucleotides then bond together and form a complete mRNA strand. The mRNA strand travels out to the cytoplasm through the nucleus. The mRNA is then met by a ribosome and tRNA. Codons and amino acids are then created. After the tRNA detaches from the mRNA strand, the amino acids are connected by a polypeptide bond. This results in a protein. So basically... Protein synthesis is going from DNA to mRNA to tRNA to a protein.
When tRNA copies mRNA it is called what?
mRNA does not copy DNA, intead, mRNA is copied FROM DNR. The process is call translation.
