"WebThe ribosome pauses and falls off the mRNA. The stretch of codons between AUG and a stop codon is called an open reading frame (ORF). Computer analysis of DNA sequence can predict the existence of genes based on ORFs. Other amino acids are specified by more than one codon--usually differing at only the third position.

WebMay 7, 2024 · Transcription is the first part of the central dogma of molecular biology: DNA → RNA. It is the transfer of genetic instructions in DNA to mRNA. Transcription happens in the nucleus of the cell. During transcription, a strand of mRNA is made that is complementary to a strand of DNA called a gene. WebJan 3, 2024 · The aa2-tRNAaa2 enters the ribosome based on codon-anticodon interaction at the A site as shown below. The GDP dissociates from EF2 as aa2-tRNAaa2 binds the anticodon in the A site. To keep elongation moving along, elongation factor (EF3) rephosphorylates the GDP to GTP, which can re-associate with free EF2.

Translation is the second part of the central dogma of molecular biology: RNA → Protein.It is the process in which the genetic code in mRNA is read, one codon at a … WebThe molecule of mRNA provides the code to synthesize a protein. In the process of translation, the mRNA attaches to a ribosome. Next, tRNA molecules shuttle the appropriate amino acids to the ribosome, one-by-one, coded by sequential triplet codons on the mRNA, until the protein is fully synthesized.
