Questions & Step-by-Step Solutions

What type of RNA is primarily involved in the regulation of gene expression through RNA interference?
Correct Answer: siRNA
  • Step 1: Understand that RNA is a molecule that helps in the process of making proteins from genes.
  • Step 2: Learn about gene expression, which is how genes are turned on or off to make proteins.
  • Step 3: Know that RNA interference is a process that can stop gene expression.
  • Step 4: Identify that siRNA, or small interfering RNA, is a specific type of RNA involved in this process.
  • Step 5: Recognize that siRNA works by finding and degrading mRNA, which is the messenger RNA that carries instructions from DNA to make proteins.
  • Step 6: Conclude that siRNA is crucial for regulating gene expression through RNA interference.
