The nuclear envelope is similar to the door of the classroom in our role-play because the door to the classroom is the edge of the room where the messenger leaves, and the nuclear envelope is the edge of the nucleus through which the messenger RNA leaves.
The hallway in our role-play is like the endoplastic reticulum in a cell because the hallway was the area through which the mRNA traveled to get to the tRNA, and the endoplastic reticulum is the area through which the mRNA travels to get to the tRNA.
The classroom in the role-play is like the nucleus in a cell because the board of the classroom is the area where the DNA code was stored, and the nucleus is the area where the DNA is stored.
Mrs. Nelson in the role-play was the same as the tRNA in the cell because Mrs. Nelson took the information from the mRNA and changed it into a code of amino acids, and the tRNA takes the information from the mRNA and changes it to a code of amino acids.
The person who walked between the classroom and Mrs. Nelson in our role-play is like the mRNA in a cell because the person in our role-play transferred the genetic information in the classroom to Mrs. Nelson, and the mRNA transfers genetic information from the nucleus to the tRNA.
