messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes).
The role of messenger RNA (mRNA) in translation is to tell the ribosomes what amino acids are needed in a specific protein and what order to put them in.
During translation, each time an amino acid is added to the growing chain, a tRNA molecule forms base pairs with its complementary sequence on the messenger RNA (mRNA) molecule, ensuring that the appropriate amino acid is inserted into the protein.
The concept that genetic information flows from DNA to RNA, and from RNA to proteins is called the central dogma of biology.
What is the function of mRNA during translation? mRNA carries an anticodon that is complementary to one or more tRNA codons. mRNA carries the code for a polypeptide's sequence of amino acids. mRNA carries amino acids to the ribosome.
mRNA carries information from DNA that are required in protein synthesis. tRNA is an adaptor molecule which carries amino acids for translation. Ribosome provides the site for protein synthesis as well as suitable enzymes which are helpful in translation process. Was this answer helpful?
mRNA carries instructions from the DNA to the ribosome work site. rRNA forms part of the structure of the ribosome and helps to connect pieces together. tRNA brings in the amino acids, which are the pieces that get strung together to make the final protein.
During protein synthesis, an organelle called a ribosome moves along the mRNA, reads its base sequence, and uses the genetic code to translate each three-base triplet, or codon, into its corresponding amino acid.
The mRNA is then pulled through the ribosome; as its codons encounter the ribosome's active site, the mRNA nucleotide sequence is translated into an amino acid sequence using the tRNAs as adaptors to add each amino acid in the correct sequence to the end of the growing polypeptide chain.
The central dogma suggests that DNA contains the information needed to make all of our proteins, and that RNA is a messenger that carries this information to the ribosomes?. The ribosomes serve as factories in the cell where the information is 'translated' from a code into the functional product.Jul 21, 2021
With the genes bound in the nucleus, transcription occurs in the nucleus of the cell and the mRNA transcript must be transported to the cytoplasm. The prokaryotes, which include bacteria and archaea, lack membrane-bound nuclei and other organelles, and transcription occurs in the cytoplasm of the cell.
