Q
Q: What is the significance of the start codon in mRNA?
Solution:
The start codon (AUG) signals the beginning of translation, indicating where the ribosome should start synthesizing the protein.
Steps: 6
Show Steps
Step 1: Understand that mRNA is a type of molecule that carries genetic information from DNA to the ribosome, where proteins are made.
Step 2: Know that the start codon is a specific sequence of three nucleotides in the mRNA.
Step 3: The start codon is always 'AUG'.
Step 4: Recognize that the start codon signals the ribosome to begin the process of translation.
Step 5: Translation is the process where the ribosome reads the mRNA and assembles amino acids to form a protein.
Step 6: Without the start codon, the ribosome would not know where to start making the protein.
