Question

A student wants to model the process of translation that occurs in a cell as part of gene expression. When planning and organizing

the materials to use in the model, the student finds the items shown in the table. Evaluate the items and select the ones that the
student needs to appropriately model the process of translation in a cell. Select ALL that apply.
A)
clothespin
)
B)
paperclip chain
the single string

Answer 1

To model the process of translation accurately, materials representing mRNA, tRNA, ribosomes, and amino acids are required. A paperclip chain could be used to represent the mRNA strand, and other items like beads could serve as tRNA with amino acids.

Step-by-step explanation:

The process of translation in a cell involves using the information encoded in mRNA to synthesize proteins.

During this process, translation machinery, including mRNA, ribosomes, tRNA, and various enzymes, works in a coordinated fashion to assemble amino acids into a polypeptide chain.

The initiation stage begins with the ribosome binding to mRNA. During elongation, tRNA molecules, each with an anticodon complementing the mRNA codon, bring specific amino acids to the growing polypeptide chain.

This process continues until a stop codon is encountered, signaling termination.

To appropriately model translation, the student would need materials that represent mRNA, tRNA, ribosomes, and amino acids.

A paperclip chain could represent the mRNA strand due to its linear nature.

Other items like beads or colored pieces of paper could serve as tRNA molecules with attached amino acids.

These essentials would allow for an interactive demonstration of how the ribosome moves along the mRNA, aligns the tRNA anticodon to the mRNA codon, and links amino acids to form a polypeptide.
