Question

refer to this diagram.
which structure holds the original code from the dna
gene?
o 1
o 2
o 3
o 4

Explanation:

In the process of protein synthesis, mRNA (messenger RNA) carries the genetic code from DNA (transcribed from the DNA gene). In the given diagram, structure 4 is mRNA. Structure 1 is the ribosome (site of protein synthesis), structure 2 is tRNA (transfers amino acids), and structure 3 is a chain of amino acids.

Answer:

4
