DNA Translation and Transcription

Question 1

Central Dogma of Biology

Answer 1

DNA is transcribed to RNA which is translated into Protein

Question 2

Steps of pre-mRNA splicing

Answer 2

1) Cleavage of the pre-mRNA occurs at the 5’ splice junction site
2) The G nucleotide located at the 5’ of the intron folds back and forms a bond with the A nucleotide of the branch point sequence. This produces a lariat structure.
3) Cleavage of the pre-mRNA occurs at the 3’ splice junction site thus removing the intron.
4) The two exons are ligated together.
