Question

what controls traits and inheritance?
○ gametes
○ nucleic acids
○ proteins
○ temperature

Explanation:

To determine what controls traits and inheritance, we analyze each option:

• Gametes are reproductive cells (sperm/egg) and don't control traits/inheritance directly.
• Nucleic acids (like DNA and RNA) carry genetic information that determines traits and is passed on during inheritance. DNA, a nucleic acid, has genes that code for traits.
• Proteins are products of gene expression and don't control inheritance (they perform functions based on genetic instructions).
• Temperature is an environmental factor and doesn't control inherent traits/inheritance.

So the correct option is the one related to nucleic acids.

Answer:

B. nucleic acids
