DNA & Genetics
What is the basic unit of heredity?
What is a Gene?
These genes help repair DNA.
What are BRCA1 and BRCA2?
This technique is used to separate DNA fragments by size.
This type of cancer occurs by chance, not inheritance.
What is sporadic Cancer?
This screening uses X-rays to detect breast cancer.
What is a mammogram?
These are different forms of the same gene.
What is Alleles?
A change in a BRCA gene is called this.
What is a mutation?
DNA moves in the direction of this charge.
What is positive end?
This Cancer type runs in families but may not be linked to a specific gene.
What is Familial Cancer?
This factor can lower cancer risk by your own choices.
What is a lifestyle factor?
This molecule contains genetic instructions.
What is DNA?
Mutations in these genes increase risk of what Cancer?
What is Breast Cancer?
These DNA fragments travel farthest down the gel.
What is smaller fragments?
This Cancer is caused by inherited gene mutations.
What is hereditary Cancer?
This factor increases risk when close relatives have cancer.
What is family history?
An Allele that is not expressed when paired with a dominant allele.
what is recessive allele?
Both Men and Women can carry mutations in these gene - True or Flase?
What is true?
This tool helps estimate the DNA fragment size.
What is DNA ladder?
This type of cancer develops from random mutations over time.
What is sporadic Cancer?
Detecting cancer early improves this outcome.
What is survival rate?
This is a permanent change in DNA sequence.
What is mutation?
This test identifies mutations in BRCA genes.
What is genetic testing?
Each visible line on a gel is called this.
what is a RFLP?
This term describes Cancer influenced by both genes and environment.
What is Familial Cancer?
This surgery removes breast tissue to reduce risk.
What is a mastectomy?
