Question

________ are changes to the nucleotides in a segment of dna that codes for a protein.

○ negative regulators
○ cdks
○ gene mutations
○ tumor suppressor genes
○ proto-oncogenes

Explanation:

• Negative regulators: Molecules that inhibit cellular processes, not DNA nucleotide changes.
• CDK's (Cyclin-Dependent Kinases): Enzymes that regulate cell cycle, not DNA changes.
• Gene mutations: Defined as alterations to the nucleotide sequence of a DNA segment that codes for a protein, matching the definition.
• Tumor suppressor genes: Genes that prevent uncontrolled cell growth, not DNA changes themselves.
• Proto-oncogenes: Normal genes that can become oncogenes, not DNA changes.

Answer:

Gene mutations
