100

Type of gene mutation where a nucleotide replaces another in a sequence.
What is a substitution?

100

A cluster of prokaryotic genes under the control of one regulatory sequence is called this.
What is an operon?

100

Active genes are found in this of eukaryotic chromosomes.
What is the euchromatin?

100

A malignant mass of cells that can establish new tumors distant from the site of the primary one, forms new blood vessels, undergoes cell division repeatedly and indefinitely and invades surrounding tissue.
What is Cancer?

100

Leading cause of cancer deaths in the US.
What is Lung Cancer?

200

Normal nucleotide sequence was TACGGCATG but became TAGGCATG which is this type of mutation.
What is deletion?

200

This part of an operon bind to the repressor protein.
What is is regulator?

200

This regulation occurs within a cell when the newly formed protein is modified.
What is posttranslational?

200

Cell death that can be programmed and is essential to normal development of cells.
What is Apoptosis?

200

Radiation, organic chemicals, viruses, and cigarette smoke are all types of these.
What are carcinogens?

300

The original sequence was CATUAUCCC. Which of the following is NOT a frameshift mutation? A. CCATUAUCCC B. ATUAUCCC C. CATUAUCGC
What is C?

300

The operon theory says the at the function of this gene is to code for a repressor molecule that can bind to the operator.
What is the regulator gene?

300

Level of primary control in eukaryotic gene activity that involves the lifespan of the mRNA and the ability of the mRNA to bind to ribosomes?
What is translational control?

300

DNA segments that are the ends of chromosomes and protect them from damage.
What are telomeres?

300

Which of the following is NOT associated with a higher cancer risk? A. Alcohol Use B. Exposure to certain hazardous chemicals C. Hormone Therapy D. Safe Sex
What is D?

400

These genes govern functions that are common to most cells.
What are Housekeeping genes?

400

This part of the operon model is a sequence of DNA bases that turns an operon on or off.
What is an operator?

400

Level of primary control in eukaryotic gene activity that involes processing early RNA transcripts to mRNA and control the rate at which mRNA leaves the nucleus.
What is posttranscriptional control?

400

Normal genes that have undergone a mutation, cause growth factors or growth factor receptors on a cell to malfunction and cause a cell to divide repeatedly but are not alien to the cell and are a mutated form of a proto-oncogene.
What is an oncogene?

400

Which of the following will not help you prevent cancer? A. decreasing high-fiber foods B. increasing broccoli consumption C. decreasing fat intake D. avoid excessive sunlight
What is A?

500

500

Level of primary control in eukaryotic gene activity that involves changes in the polypeptide chain before it becomes functional.
What is posttranslational control?

500

Genes that are anti-oncogenes that code for proteins that inhibit cell division.
What are tumor-suprpessor genes?

500

Which will not help you in protecting yourself from cancer? A. eating vitamin rich roods B. reducing salt and nitrate cured foods C. reducing your weight D. using alcohol
What is D?
