WebThis enzyme is ultimately in charge of the formation and growth of new DNA strands. Elongation DNA Polymerase can begin synthesising new strands of DNA to match the templates once it has linked to the two unzipped strands of DNA. Only free nucleotides can be added to the 3′ end of the primer by DNA polymerase. WebMar 31, 2024 · Unwinding and unzipping of DNA strand/double helix ... Elongation: In the elongation phase of translation, the tRNA with the correct corresponding anticodon will match with the corresponding mRNA codon. A peptide bond is formed between the methionine from the first tRNA with the second amino acid from the second tRNA. The …
