Q
Q: In the context of gene expression, what is the role of mRNA?
Solution:
mRNA (messenger RNA) carries the genetic code from DNA to ribosomes, where proteins are synthesized.
Steps: 5
Show Steps
Step 1: DNA contains the genetic information needed to make proteins.
Step 2: When a cell needs to make a protein, it first makes a copy of the relevant part of the DNA in the form of mRNA.
Step 3: mRNA is like a messenger that carries this genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm.
Step 4: Ribosomes are the sites where proteins are made, using the information carried by the mRNA.
Step 5: The ribosomes read the mRNA sequence and assemble the corresponding amino acids to form a protein.
