Practical 1 Exam Questions With
Answers
Phenotype - CORRECT ANSWER✔✔-An organism's physical appearance,
| | | | | |
or visible traits.
| | |
Genotype - CORRECT ANSWER✔✔-An organism's genetic makeup, or
| | | | | | | |
allele combinations.
|
Allele - CORRECT ANSWER✔✔-one of a number of different forms of a
| | | | | | | | | | | |
gene
Evolution - CORRECT ANSWER✔✔-changes in allele frequency of a
| | | | | | | | |
population ★ |
natural selection - CORRECT ANSWER✔✔-the differential survival and
| | | | | | | |
reproduction of individuals due to differences in phenotype
| | | | | | |
,Adaptation - CORRECT ANSWER✔✔-the process of becoming adapted
| | | | | | | |
to an environment; an anatomical, physiological, or behavioral change
| | | | | | | | |
that improves a population's ability to survive
| | | | | |
Fitness - CORRECT ANSWER✔✔-the measure of an organism to pass its
| | | | | | | | | | |
genetic material to its offspring
| | | |
genetic variation - CORRECT ANSWER✔✔-The variety of different types
| | | | | | | | |
of genes in a species or population.
| | | | | |
Hardy-Weinberg Principle/Equation ★ - CORRECT ANSWER✔✔- | | | | |
principle that allele frequencies in a population will remain constant
| | | | | | | | | |
unless one or more factors cause the frequencies to change
| | | | | | | | |
Mouse genotypes - CORRECT ANSWER✔✔-Black: BB
| | | | |
Reddish-Brown: Bb |
White: bb |
Prokaryotes vs. Eukaryotes - CORRECT ANSWER✔✔-PROKARYOTES
| | | | | |
("pro" = before, "karyon" = nucleus)
| | | | |
| 1. Unicellular: Bacteria and blue-green algae
| | | | |
| 2. No nucleus; nucleiod region with single
| | | | | | |
| circular DNA; single chromosome;
| | | |
, | 3. Smaller
| |
| 4. Cell wall in all
| | | | |
| 5. Ribosomes (30 & 50S)
| | | |
| 6. No membrane-bound organelles
| | |
| 7. Transcription and Translation in cystosol
| | | | | |
EUKARYOTES ("eu" = true, "karyon" = nucleus)
| | | | | |
| 1. Unicellular or Multicellular: protists, fungi,
| | | | |
| plants & animals
| | |
| 2. Nucleus; consist of mutiple chromosomes
| | | | |
| 3. Bigger
| |
| 4. Cell wall ONLY in fungi & plants
| | | | | | |
| 5. Ribosomes (40 & 60S)
| | | |
| 6. Membrane-bound organelles
| |
| 7. Transcription in nucleus; Translation in cytosol
| | | | | | |
BOTH
| 1. Cytoplasm
|
| 2. DNA
|
| 3. Cell membrane
| | |
| 4. ribosomes
