Question

column a

1. a dna

a. z

1. b mrna

b. q

1. c ribosome

c. x
4 d protein
d. y

Explanation:

Step1: Analyze DNA (1a)

In the diagram, Y is the double - helix structure which represents DNA. So DNA (1a) corresponds to d (Y).

Step2: Analyze mRNA (2b)

mRNA is the single - stranded molecule that is transcribed from DNA and is used in translation. In the diagram, Z represents mRNA. So mRNA (2b) corresponds to a (Z).

Step3: Analyze Ribosome (3c)

Ribosomes are the organelles where translation occurs. In the diagram, Q represents the ribosome. So Ribosome (3c) corresponds to b (Q).

Step4: Analyze Protein (4d)

Protein is the product of translation. In the diagram, X represents the newly synthesized protein. So Protein (4d) corresponds to c (X).

Answer:

1. a. DNA - d. Y
2. b. mRNA - a. Z
3. c. Ribosome - b. Q
4. d. Protein - c. X
