Question

1. the diagram shows important structures found in a cell. two structures, w and z, are labeled. which statement best describes structure w and structure z? structure w is a gene and structure z is a chromosome structure w is a chromosome and structure z is a gene structure w is an amino acid and structure z is a nucleic acid structure w is a nucleic acid and structure z is an amino acid

Explanation:

• Chromosomes are thread - like structures in the nucleus of a cell. They are made up of DNA (a nucleic acid).
• A gene is a segment of DNA (nucleic acid) that contains the instructions for making a specific protein. In the diagram, structure \(W\) has the shape of a chromosome (the \(X -\) shaped structure which is a condensed form of DNA during cell division) and structure \(Z\) is a segment of the DNA (nucleic acid) molecule, which is a gene.
• Amino acids are the building blocks of proteins, not related to the chromosome - gene relationship shown in the diagram.

Answer:

Structure \(W\) is a chromosome and Structure \(Z\) is a gene.
