what happens in translation and transcription
During translation, which is the second major step in gene expression, the mRNA is read according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins (Figure 2).
Transcription is the first stage of protein synthesis: 1) mRNA is produced, but to be produced, the gene to be transcribed is dipped into the nucleolus so the hydrogen bonds between the complementary bases are broken.
