Genetics Final Exam Study Guaranteed Success
Key Concepts in Genetics and Cancer
1. Greatest Risk Factor for Cancer:
- Age is the greatest risk factor for developing cancer.
2. Function of the Immune System:
- The immune system works by attacking anything recognized as foreign.
3. Example of Basic Research:
- An example of basic research is studying how plants convert carbon dioxide into sugar.
4. Definition of Genetics:
- Genetics is defined as the scientific study of heredity.
5. DNA Components:
- The DNA components adenine, thymine, guanine, and cytosine are known as bases.
6. Gregor Mendel's Contribution:
- Gregor Mendel claimed that each individual carries a pair of "factors" for a given trait.
7. Current Terminology for Mendel's "Factors":
- What Mendel referred to as "factors" is now called genes.
8. Prior Predictions About Rose Crossbreeding:
- Before Mendel's principles were understood, one might have predicted that crossbreeding a red rose
with a yellow rose would result in all orange roses.
,9. Purpose of Karyotypes:
- The primary purpose of preparing karyotypes is to diagnose or rule out specific genetic disorders.
10. Eugenics Overview:
- Eugenics is regarded as a dubious method aimed at improving the human species through selective
breeding.
11. Significance of Carrie Buck:
- Carrie Buck is notable in genetics history because she was sterilized after a U.S. Supreme Court ruling
deemed her feebleminded.
12. Hereditarianism Concept:
- Hereditarianism posits that all human traits are solely determined by genes.
13. Decline of the Eugenics Movement:
- The decline of eugenics in the U.S. during the early 20th century was influenced by its misuse for
social and political ends by the Nazis.
14. Induced Pluripotent Stem Cells:
- Induced pluripotent stem cells are produced from normal body cells.
15. Gene Therapy Explanation:
- Gene therapy is best described as the insertion of normal genes to replace mutant ones.
16. Impactful Methods in Human Genetics:
- The methods of molecular genetics have significantly impacted human genetics in recent decades.
17. Human Pedigree Representation:
- A human pedigree represents the inheritance of a trait across several generations within a family.
,18. Genomics and Recombinant DNA Technology:
- The development of recombinant DNA technology initiated the genomic era, allowing geneticists to
plan the sequencing of the human genome's 3.2 billion nucleotides.
19. Nucleotide Sequence Function:
- The nucleotide sequence specified by a gene determines the phosphate groups that make up
proteins. (Note: This statement may need revisiting; the nucleotide sequence actually encodes amino
acids, not phosphate groups, which are part of the nucleotide structure.)
20. Transmission Genetics Studies:
- Transmission genetics focuses on the patterns of inheritance as traits are passed down through
generations.
21. Translational Medicine:
- The integration of research and medicine that aims to quickly translate findings into methods for
diagnosing and treating diseases is known as translational medicine.
22. SNP (Single Nucleotide Polymorphism):
- The simplest form of genetic variation is a single nucleotide change called an SNP.
23. Haplotype Definition:
- A set of genetic markers that are located close together on a single chromosome is referred to as a
haplotype.
24. DNA Microarrays Functionality:
- New technologies allow for screening an individual's entire genome using DNA microarrays that
contain DNA from across the human genome.
25. Composition of Genes:
- In the mid-20th century, it was discovered that genes are composed of DNA, which is part of cellular
structures known as chromosomes.
, 26. Recombination Process:
- The process by which genes move from one chromosome to another is known as recombination.
27. Structure of Nucleotides:
- Each nucleotide in a DNA strand is made up of a sugar, a base, and a phosphate group.
28. Amino Acid Functionality:
- Chemical subunits called amino acids combine to form proteins.
29. Pattern of Inheritance in Transmission Genetics:
- Transmission genetics examines the patterns of inheritance as traits are transmitted from generation
to generation.
30. Cytogenetics Field:
- Cytogenetics is the branch of genetics focused on mapping genes and studying chromosome
structure and abnormalities.
31. DNA Structure and Function:
- DNA is a helical molecule made up of two strands of nucleotides that serves as the primary carrier of
genetic information.
