Conversion of mrna strand into amino acid sequence at ribosome?

∙ 12y ago
The mRNA is copied, in reverse, by tRNA in the ribosome. This then reproduces the correct DNA codon. The tRNA collects the appropriate amino acid and brings it to the polypeptide chain being formed in the ribosome, and attaches it in the appropriate order, this process repeating until the entire protein is synthesized.

How would the amino acid sequence produced by the mutant strand compare to the amino acid sequence produced by series 1?
one amino acid in the sequence would change
What regulates protein production in the nucleus?
First a primary transcript strand is copied off a DNA strand in the nucleus in a process called transcription. The DNA strand acts as a template for the newly created primary transcript strand. The primary transcript is made up of introns and exons. The introns are taken out and the exons are binded together by enzymes. THis new strand of exons is called messenger RNA or mRNA. Next the mRNA strand leaves the nucleus through the nuclear pores, and binds to a ribosome. Each base triplet on the mRNA strand is known as the codon. The codon binds to an anti-codon which is found on a unit of transfer RNA. The transfer RNA (tRNA) brings with it a particular amino acid that is coded for to the ribosome. The tRNA then exits the ribosome, as the amino acid it brought binds to the next amino acid, forming a polyeptide (protein) chain. This process continues until a stop sequence is reached, where the protein chain is released from the ribosome and protein synthesis is complete. Some notable facts are that the triplet sequence that initially binds to the ribosome (the start sequence) is always AUG, and the three stop sequences are UAA, UAG and UGA.
Where does the process of translation do in mRNA?
The newly spliced mRNA binds to a ribosome. tRNA molecules migrate towards the ribosome, these tRNA molecules carries a specific amino acid. The ribosome allows two tRNA molecules into the ribosome at a time. The tRNA molecules have complementary anti-codons to the codons present on the mRNA strand. Two tRNA move into the ribosome and their anti-codons join to complementary codons on the mRNA strand. As one molecule leaves the ribosome, its amino acid forms a peptide bond with an amino acid on the adjacent tRNA molecule, with the help of ATP and an enzyme. As the ribosome moves along the the mRNA strand, a polypeptide chain is created. The ribosome stops reading the mRNA strand when it reaches a stop codon.
What determines the sequence of amino-acids in a protein?
The DNA carries the instructions for protein synthesis. These instructions are copied onto mRNA, which then travels to the ribosome. At the ribosome, the mRNA is translated into the correct sequence of amino acids.
Protein synthesis occurs at this organelle?
mRNA functions as a messenger from the original DNA helix in the 'nucleus' (transcription), and is then transported to the 'cytoplasm' where the information in the mRNA is translated (translation) into a sequence of amino acids making up a polypeptide.
When building an amino acid sequence what molecule picks up the amino acids and brings them to the ribosome?
the tRna.

How cell produces protein?
Cells make proteins at ribosomes. DNA in the nucleus is copied by the cell in the form of RNA strands. These RNA strands leave the nucleus and enter the cytosol, where they encounter ribosomes. The ribosome runs along the RNA strand, reading the sequence of nucleotide bases in the strand. Each sequence of three bases (e.g. AGC or CCG) in the RNA encodes a particular amino acid molecule. As the ribosome reads the RNA sequence, it builds a string of different amino acid molecules according to the sequence it reads from the RNA molecule. When the ribosome stops reading the RNA, it releases it's newly built string of amino acids, which folds up, becoming a protein. The amino acids themselves are made by the cells from ammonium and nitrate that the organism has consumed or absorbed from the environment.

What is the amino acid sequence for DNA strand with the base sequence DNA-AGGTACGAT?
Serine, Methionine , Leucine.
What determines the sequence of amino-acids in a protein?
The DNA carries the instructions for protein synthesis. These instructions are copied onto mRNA, which then travels to the ribosome. At the ribosome, the mRNA is translated into the correct sequence of amino acids.
What brings amino acids into ribosome to be Assembled into protein?
tRNA brings amino acids from the cytoplasm to the ribosome to be assembled into a protein. The tRNA anticodon pairs with its complimentary mRNA codon in order to place the amino acid in the correct sequence.

What is the amino acid sequence for a DNA strand with the base sequence DNA-AGGTAGAT?
Serine, Isoleucine. Last codon is incomplete.
How do you make a protein from DNA?
mRNA transcribes a strand of DNA and carries the genetic code to a ribosome, where the mRNA code is translated by tRNA into a strand of amino acids, making a protein.
Which RNA carries the amino acid which is added to the protein strand?
tRNA actually caries various AA's to the assembled ribosome to ne attached to the nascent and/or growing RNA strand
