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

100

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

100

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

100

What is Cancer?
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.

100

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

200

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

200

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

200

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

200

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

200

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

300

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

300

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

300

What is translational control?
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?

300

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

300

What is D?
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

400

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

400

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

400

What is posttranscriptional control?
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.

400

What is an oncogene?
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.

400

What is A?
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

500

Who are Raphael, Donatello, Michelangelo, and Leonardo?
Name the Teenage Mutant Ninja Turtles.
 

500

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

500

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

500

What is D?
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
