Protein Synthesis
Question | Answer |
---|---|
1 | mRNA is made from DNA and the genetic code is copied |
2 | Genetic code is fromed int he code of codons on the mRna |
3 | mRNA leaves the nucleus and attaches itself to a ribosome in the cytoplasm |
4 | mRNA first(stop) codon attaches to the ribosome signaling the begining of translation |
5 | tRNA brings along Methionine, pairs up the anticodon with the right codon on the mRNA |
6 | mRNA moves along the ribosome to the next codon |
7 | Next tRNA brings another amino acid to the mRNA and the two amino acids are joined by peptide bond |
8 | tRNAs are released one by one as the amino acids form a peptide chain |
9 | Protein syntehsis (translation) ends when mRNA reaches a stop codon |
10 | A polypeptide chain is formed which is used to make different proteins |
