Questions & Step-by-Step Solutions

What is the first step of protein synthesis?
  • Step 1: The process of protein synthesis begins in the cell's nucleus.
  • Step 2: The DNA molecule unwinds and separates to expose a specific gene.
  • Step 3: An enzyme called RNA polymerase binds to the DNA at the start of the gene.
  • Step 4: RNA polymerase reads the DNA sequence and synthesizes a complementary strand of mRNA.
  • Step 5: The newly formed mRNA strand detaches from the DNA and is processed before leaving the nucleus.
