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?

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

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?

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?

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.
