Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the regulatory mechanisms?Involves promoter strength, transcription factor recruitment, chromatin accessibility, and epigenetic modifications
2. What is the physiological relevance?Essential for rapid cell growth, development, stress response, and immune function
3. Why do cells need to make many copies of RNA quickly?Making many RNA copies fast lets cells produce the proteins they need quickly, such as during cell division, growth, or when facing danger.
4. How does transcriptional amplification happen at the molecular level?It happens when many RNA polymerase molecules bind to one promoter at the same time, often helped by special transcription factors, or when the gene is organized in copies that can be read in parallel.

Transcription Factors: Proteins that bind to specific DNA sequences to regulate gene transcription rates.
Chromatin Remodeling: Changes in DNA packaging that affect gene accessibility and transcription.
Oncogenes: Genes that have the potential to cause cancer when mutated or overexpressed.
Tumor Suppressor Genes: Genes that protect cells from becoming cancerous; their inactivation can lead to cancer.
