Ribosomes translate messenger RNA (mRNA) into protein in the cytosol, outside the nucleus. Many proteins which are destined for exocytosis (released from the cell into the environment) or integration into the cell membrane (for signalling) are made by ribosomes which become associated with the endoplasmic reticulum, or ER, (also in the cytosol). In this case, proteins are translated by ribosomes and simultaneously inserted into the ER, and later transported in vesicles to the cell membrane.

One binding site on a ribosome holds an mRNA molecule and the other two binding?

sites hold tRNA molecules. The mRNA binding site is where the mRNA molecule binds and is read during translation. The tRNA binding sites are where tRNAs carrying amino acids bind and deliver them to the growing polypeptide chain.


What organelle assists tRNA in translating the mRNA in the cytoplasm?

Ribosomes are the organelles that assist tRNA in translating the mRNA in the cytoplasm. Ribosomes read the mRNA sequence and help assemble amino acids into proteins based on the instructions encoded in the mRNA.


Can mRNA and tRNA be reused?

Yes, mRNA and tRNA can be reused multiple times during protein synthesis. mRNA molecules are read by ribosomes to synthesize proteins, and tRNA molecules bring specific amino acids to the ribosome according to the mRNA template. Once a protein is synthesized, the mRNA and tRNA molecules can be released and used again in the cell.


What type of molecule is the tRNA bring to the mRNA?

tRNA brings amino acids to the mRNA during protein synthesis. Each tRNA molecule carries a specific amino acid and has an anticodon that base pairs with the complementary codon on the mRNA, ensuring the correct amino acid is added to the growing protein chain.


When tRNA copies mRNA it is called what?

When tRNA copies mRNA, it is called translation. During translation, tRNA molecules carry specific amino acids to the ribosome, where they align with the complementary codons on the mRNA to synthesize a protein.


What the difference between mRNA and tRNA?

mRNA is the RNA that carries information during transcription and translation. It has codons, which match up with the anticodons on tRNA. tRNA is the RNA that bonds to amino acids and transfers them to ribosomes, and mRNA.


What process do mrna and 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.


Do amino acids bind directly to the mRNA?

No, amino acids do not bind directly to mRNA. Amino acids are brought to the ribosome by transfer RNA (tRNA), which carries the appropriate amino acid based on the mRNA codon. The ribosome then catalyzes the formation of peptide bonds between adjacent amino acids to form a protein.


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 does trna does that mrna does not have?

Protein Parts


Are codons found in mRNA or tRNA?

mRNA is made up of anticodons


What does trna uses to match to the mrna?

tRNA contains an anticodon which is a sequence of three nitrogen bases that is complimentary to a particular mRNA codon.
