Worked Solution & Example Answer:The first step of gene expression is A - VCE - SSCE Biology - Question 24 - 2011 - Paper 1
Step 1
B. transcription of DNA.
Answer
The first step of gene expression is transcription of DNA. During this process, the DNA sequence of a gene is transcribed to produce messenger RNA (mRNA). This occurs in the nucleus of the cell, where the DNA serves as a template for the synthesis of RNA. The mRNA then exits the nucleus and is translated into a protein in the cytoplasm.
