Genetics
Genetics is the study of genes, heredity, and genetic variation in living organisms.A gene is the molecular unit of heredity of a
living organism. A gene is a portion (or sequence) of DNA that
codes for a known cellular function (another definition)
Heredity is the passing of phenotypic traits from parents to their offspring, either through asexual reproduction or sexual reproduction.
Genetic variation, variation in alleles of genes, occurs between individuals or between populations.
Branches of GeneticsClassical Genetics: It is the oldest
discipline in the field of genetics, going back to the experiments of Gregor Mendel. The study of the transmission of genotype from parent to offspring.
Human genetics: is the study of heredity and variation in the humans.
Cytogenetics: is the study of chromosomes and chromosome abnormalities
Population genetics: The genetics of the different populations of animal and plant species.
Molecular genetics: is the study of the structure and function of genes at a molecular level.
Differences between Prokaryotic and Eukaryotic cells Prokaryotic cells Eukaryotic cells
Taxonomic groups Bacteria, Cyanobacteria all protists, fungi, plants, animals
Size Usually <5 µm Usually >5 µm Nucleus No true nucleus, no
nuclear membraneTrue nucleus, nuclear membrane
Genetic material One circular molecule of DNA, little protein
Linear DNA molecules complexed with histones
Mitosis and Meiosis
Absent present Eukaryotic cells contain many different organelles that
perform specific functions. Such as, nuclei, mitochondria, chloroplasts contain genomes.
The eukaryotic cell possesses some structures that are critical for mitosis and meiosis: centrosomes and microtubules/spindle fibers.
Classical Genetics: It is the oldest discipline in the field of genetics, going back to the experiments of Gregor Mendel. The study of the transmission of genotype from parent to offspring.
Human genetics: is the study of heredity and variation in the humans.
