Explain the process of gene expression in as few steps as possible.

Homework Answers

Answer #1

The process of gene expression is as below:

  1. DNA is first transcribed to form RNA i.e mRNA via the process of transcription in the nucleus.
  2. mRNA formed undergoes post transcriptinal modification such RNA splicing, capping and polyadenylation.
  3. Modified mRNA is transported out of the nucleus into the cytoplasm where the mRNA directs the process of polypeptide synthesis via translation process.
  4. The transaltion machinery consists of ribosomes,tRNA and rRNA .
  5. The tRNA possess anticodon that recognise the codon of the mRNA and carry the specific aminoacid to the ribosomes.First codon read is for aminoacid methionine.
  6. As aminoacids are added ,peptide bond is formed between them and polypeptide grows in length until it recognises the stop codon.
  7. The polypeptide is then released and undergoes post translational modifications and folding to form the native functional protein.

Explain the principle of “differential gene expression” and how different genes are expressed in different cell types. Describe in detail the two main mechanisms of the transcriptional regulation of gene expression.
