Question

which of the following statements describe how genes, proteins, and traits are related? select all that apply. proteins carry out activities in the cell that affect traits. proteins are molecules in the cell that encode genes. the nucleotide sequence of a gene determines the amino acid sequence of a protein. genes carry out functions in the cell that include providing structure and controlling chemical reactions. genes contain information about traits.

Explanation:

1. "Proteins carry out activities in the cell that affect traits" - Proteins are the functional molecules; their actions (like enzymes, structural roles) influence traits. For example, a protein enzyme involved in pigment synthesis affects eye color.
2. "The nucleotide sequence of a gene determines the amino acid sequence of a protein" - This is the central dogma concept: DNA (gene) sequence is transcribed to RNA, then translated to a protein's amino acid sequence.
3. "Genes carry out functions in the cell that include providing structure and controlling chemical reactions" - Genes encode proteins. Proteins can be structural (like collagen) or enzymes (controlling reactions), so genes indirectly do this via protein synthesis.
4. "Genes contain information about traits" - Genes are segments of DNA with the code (alleles) that determine traits (e.g., a gene for hair color has info for brown/black/blonde etc.).
5. "Proteins are molecules in the cell that encode genes" - Incorrect. Genes (DNA) encode proteins, not the other way around. Proteins don't encode genetic information.

Answer:

• Proteins carry out activities in the cell that affect traits
• The nucleotide sequence of a gene determines the amino acid sequence of a protein
• Genes carry out functions in the cell that include providing structure and controlling chemical reactions
• Genes contain information about traits
