Answer:
Y: tRNA
Z: DNA
Explanation:
This question involves two different nucleic acid molecules that are involved in protein production. Xavier used a chart to highlight the functions these nucleic acids perform during protein synthesis.
- Transfer RNA known as tRNA is a type of RNA molecule found in the ribosomes. It functions to read the mRNA codon and carry corresponding amino acid to the ribosomes for linking with one another. Based on this, "Y" on the chart is a tRNA molecule.
- Deoxyribonucleic acid, also known as DNA, is a molecule found in the NUCLEUS whose function is to store the genetic information in the cell. DNA carries the information needed for the synthesis of protein. Based on this, Z is a DNA molecule.
