Imagine Jackson, Harper, and William are in a science quiz competition. The quizmaster asks, 'Which process and product are represented in Diagram 2?' Can you help them answer?
Process: Transcription
Product: mRNA
Process: Translation
Product: protein
Process: Replication
Product: tRNA
Process: Recombination
Product: polymerase
Answer explanation
The question asked about the process and product represented in a given diagram. The correct answer is 'Process: Transcription, Product: mRNA'. This indicates that the diagram was illustrating the process of transcription, where a segment of DNA is copied into mRNA. This mRNA then serves as a template for protein synthesis. The other options, including translation, replication, and recombination, are not correct in this context.
