What is produced in transcription?
Transcription is the process of producing a strand of RNA from a strand of DNA. Similar to the way DNA is used as a template in DNA replication, it is again used as a template during transcription. The information that is stored in DNA molecules is rewritten or ‘transcribed’ into a new RNA molecule.
What is produced during transcription quizlet?
In transcription, the RNA nucleotides are linked by the transcription enzyme, RNA polymerase. It produces primary transcript RNA.
What is the end product of transcription?
The product of transcription is RNA, which can be encountered in the form mRNA, tRNA or rRNA while the product of translation is a polypeptide amino acid chain, which forms a protein….How is Translation Different from Transcription?
| Transcription | Translation | |
|---|---|---|
| Template | DNA | mRNA |
| End Product | RNA | Protein |
What is the purpose of transcription and where does it occur?
Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.
How does the process of translation work?
Translation is the process that takes the information passed from DNA as messenger RNA and turns it into a series of amino acids bound together with peptide bonds. The ribosome moves along the mRNA, matching 3 base pairs at a time and adding the amino acids to the polypeptide chain.
What is the anticodon for AAA?
DNA is AAA. Its mRNA will be UUU. The anticodon for UUU will be AAA.
How many codons make an amino acid?
The three-letter nature of codons means that the four nucleotides found in mRNA — A, U, G, and C — can produce a total of 64 different combinations. Of these 64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis.
Why are there 64 codons for 20 amino acids?
Because DNA consists of four different bases, and because there are three bases in a codon, and because 4 * 4 * 4 = 64, there are 64 possible patterns for a codon. Since there are only 20 possible amino acids, this means that there is some redundancy — several different codons can encode for the same amino acid.
