Describe the locations reactants and products of transcription and translation?
Transcription is located in the nucleus, and translation is located in the cytoplasm. The product of transcription is RNA, and the product of translation is protein. The reactants for transcription is DNA, and the reactants for translation is mRNA and tRNA.
What happens to mRNA after protein synthesis?
Some stays around for a while so many polypeptide chains can be run from it, while other mRNA is degraded in the cytosol almost immediately by enzymes designed for the task. Depends on how much protein product is needed in the representation of the particular mRNA.
What is directly responsible for the sequence of amino acids in a protein?
The sequence of codons in mRNA, or messenger RNA, is most directly responsible for the sequence of amino acids in a protein. Each codon is comprised of 3 nucleotides.
Which molecules match mRNA codons to specific amino acids?
Starting from the translation start codon in the mRNA molecule, each three bases corresponds to a single amino acid, until you reach the stop signal. Some amino acids have more that one triplet that codes for them (redundancy). Some parts of the mRNA molecule are untranslated and therefore do not correspond to amino acids.
What identifies the specific amino acid for tRNA?
The messenger RNA strand. When the tRNA inserts itself between the two portions of the ribosome attached to the mRNA strand, the specific tRNA depends on the 3 nitrogen bases on the mRNA (the codon) that are about to be read. The tRNA that arrives has a corresponding "anticodon" to go with the codon on the mRNA. For example, if the nitrogen bases on the mRNA strand are adenine, guanine, and cytocine the tRNA will have an anticodon of uracil, cytocine and guanine. The tRNA that has the corresponding anticodon to the codon on the mRNA will bring with it a specific amino acid but it is the codon on the mRNA that ultimately decided which amino acid is next in line.
Does translation involve the formation of mRNA?
No, transcription involves the formation of mRNA.
What is serves as the temple during translation?
mRNA
What is used during RNA translation.?
mRNA- a transcript of DNA which serves as instuctions for polypeptide formation. amino acid- a single buildin block of protein. tRNA- a molecule that carries a specific amino acid and recognizes its complementary base sequence on an mRNA strand. ribosome- an organelle which serves as the "factory" where amino acids are addes to a growing polypeptide chain.
The mRNA molecule is completed by the formation of what?
Hydrogen bonds
What organelle serves as a meeting place for the tRNA and mRNA?
Ribosome
RNA molecule that is template for translation?
DNA serves as a template for transcribing mRNA.
The mRNA molecule is completed by the formation of what between the rna?
The mRNA molecule is completed by the formation of hydrogen bonds. These bonds are between the RNA nucleotides, which then separate from the DNA.
How does a eukaryoyic cell use instructions from the nucleus to make proteins?
by transcription(formation of mRNA) and then translation( formation of polypeptide/protein)
What role does the mRNA fulfill?
The mRNA (messenger RNA) serves as the intermediary molecule between DNA and protein synthesis. It carries the genetic information from the DNA to the ribosomes in the cytoplasm, where it is used as a template to synthesize proteins. It acts as a "messenger" to convey the instructions for protein synthesis from the DNA to the ribosomes.
The formation of proteins by using information contained in DNA and carried by mRNA?
Transcripton
Which RNA is responsible for bringing amino acids to the factory site for protein formation?
mRNA
What is serves as the template during transcription?
The process of generating an mRNA copy of a DNA molecule is called transcription. Here, an enzyme called RNA polymerase opens up the double stranded DNA and begins inserting RNA bases using DNA as the template. Every time the enzyme encounters an Adenine (A), it inserts a Uracin (U) to the growing mRNA strand. When it encounters a cytosine (C), it inserts a Guaning (G) into the growing RNA strand. This is how DNA acts as a template for mRNA
