Question

use the information below to answer questions 10 - 11
a student submitted the following explanation for how
the structure of dna determines the structure of
proteins

dna and proteins
dna in the ribosomes is made up of
base pairs that are transcribed to
crna trna carries the information
through the cell to the nucleus. at the
nucleus, the unique code of a trna
strand is translated to assemble amino
acids into a protein. the protein has a
unique structure that determines its
function within the cell.

which of the following are functions that proteins perform to support life? select three that apply.
hold muscle cells together.
perform functions within the cell.
serves as the genetic code for the body.
function as enzymes for chemical reactions.

Explanation:

1. Analyze each option:

• "Hold muscle cells together": Proteins like structural proteins can hold cells together, this is a function of proteins.
• "Perform functions within the cell": Proteins have various functions within cells (e.g., enzymatic, structural), this is correct.
• "Serves as the genetic code for the body": DNA, not proteins, serves as the genetic code, so this is incorrect.
• "Function as enzymes for chemical reactions": Many enzymes are proteins and they catalyze chemical reactions, this is correct.

1. Select the three correct options: "Hold muscle cells together", "Perform functions within the cell", "Function as enzymes for chemical reactions".

Answer:

• Hold muscle cells together.
• Perform functions within the cell.
• Function as enzymes for chemical reactions.
