DNA Worksheet

This document contains a quiz about DNA, RNA, and genetics. It asks questions about the structure of DNA, the differences between DNA and RNA, the three types of RNA and their functions, how DNA codes for RNA and proteins, and identifying amino acids from mRNA codons. Students are asked to fill in blanks and provide short answers testing their knowledge of central dogmas and processes of molecular genetics.
