Question

Cytochrome C Study

A scientist wants to study the cytochrome c gene of a fruit fly. The DNA for the gene is extracted and subjected to several treatments.

Use the passage to answer the next four questions.

Part C:

If this gene were found to be expressed at different levels in different cells of the same organism, what would be responsible?

transcription factor

rRNA

ribosome

RNA polymerase

Answer 1

[AI-generated answer — Bot GPT 3.5]

The correct answer is transcription factor. Transcription factors are proteins that bind to specific DNA sequences and regulate the transcription of genes. They can activate or inhibit the transcription of target genes, leading to different levels of gene expression in different cells. rRNA, ribosomes, and RNA polymerase are all involved in the process of translation, not gene expression.
