WELL DEFINED ANSWERS 100%GUARANTEED PASS!!!-
Portage Learning
Who used pea plants to model how traits are inherited from generation to generation? -
CORRECT ANSWER-Gregor Mendel, an Augustinian Monk
What does Gregor Mendel's experiment explain? - CORRECT ANSWER-The basic
foundations of trait transmission in modern genetics, so he is considered a forefront name in
genetics.
What is an example of a mutation that became "normal"? - CORRECT ANSWER-The gene
that allows us to digest lactose
What defines genetics? - CORRECT ANSWER-The study of heredity
Epigenesis - CORRECT ANSWER-Concept correctly hypothesized that a fertilized human
egg undergoes specific developmental events that eventually lead to the formation of a human
Spontaneous generation - CORRECT ANSWER-Living things could spontaneously generate
from nonliving components
What book did Charles Darwin publish that postulated his theory of natural selection? -
CORRECT ANSWER-The Origin of Species
,2|Page
Who theorized natural selection? - CORRECT ANSWER-Charles Darwin
Preformation - CORRECT ANSWER-Concept that a fertilized egg contains a tiny version of a
completely developed adult (homunculus)
Who introduced cell theory? - CORRECT ANSWER-Mathias Schledein and Theodor
Schwann
What did Mathias Schledein and Theodor Schwann propose? - CORRECT ANSWER-That all
living organisms were composed of organized structures called cells and that these cells were
derived from identical precursor cells
What does genetics focus on primarily? - CORRECT ANSWER-The understanding of genes
and how they contribute to the passing of traits
What is the chromosomal theory of inheritance? (1910s) - CORRECT ANSWER-It showed
that both heredity and development depended on the passing of genetic information via genes
that were contained within chromosomes
What birthed today's genetics? - CORRECT ANSWER-The merge of Mendel's genetics
teachings with the theory of inheritance
What are the four different nucleotides which have different nitrogenous bases? - CORRECT
ANSWER-Adenine (A), Guanine (G), Thymine (T), and Cytosine (C)
How do bacterial restriction enzymes function? - CORRECT ANSWER-By cutting and
inactivating the DNA of invasive viruses
,3|Page
What is biotechnology? - CORRECT ANSWER-Using genetics to make products (genetically
modified crops resist pests and herbicides to enhance nutrition)A
What does transgenic mean? - CORRECT ANSWER-Advantageous heritable traits have been
introduced using recombinant DNA technology
What is. found in the nucleus of a cell and holds the information for almost all living organisms -
CORRECT ANSWER-Chromosomes
Each organism carries a specific number of chromosomes called the? - CORRECT ANSWER-
Diploid number (2n)
Chromosomes exist within cells in pairs called? - CORRECT ANSWER-Homologous
chromosomes
Genetic mutations result in? - CORRECT ANSWER-Different alleles
Normal in genetic terms is the gene that occurs most often in a population, this gene is the? -
CORRECT ANSWER-Wild-type allele
Phenotype - CORRECT ANSWER-Observable feature produced by a gene
Genotype - CORRECT ANSWER-Set of alleles that are carried by an organism that produce a
certain trait
, 4|Page
What was the first biologic product ever produced from a transgenic animal? - CORRECT
ANSWER-ATryn (isolated from the milk of genetically engineered goats) (can prevent blood
clots in peoples who have a rare blood disorder that involved a lack of sufficient antithrombin)
What were the first model organisms? - CORRECT ANSWER-Mice and fruit flies
Module 2
Gametes
sex cells (sperm and egg)
Karyotype
A display of the chromosome pairs of a cell arranged by size and shape.
Process for karyotyping:
- Isolate WBCs
- Stain WBCs
- Photograph under microscope
- Cut to organize chromosomes by size
Cytogeneticist:
a scientist who studies chromosomes under the microscope
BRCA1 gene
- susceptibility gene for type 1 breast cancer
- tumor suppressor gene that is produced in normal breast tissue and responsible for DNA repair.
BRCA1 mutation
- Genetic mutation within the protein that inhibits DNA repair, increasing breast and ovarian
cancer risk to 80% over lifetime
Protein functions:
- structural support
- controls cellular metabolism
