Explanation:
Genetics is the science of heredity and variation, explaining how traits are passed from parents to offspring and why individuals differ. Ecology studies organisms and environment, embryology deals with development, paleontology with fossils. Gregor Mendel is the father of genetics. The term 'genetics' was coined by William Bateson.
Explanation:
Prokaryotic DNA is typically circular, double-stranded, and found in a nucleoid region without a nuclear membrane. It is not associated with histones (though some Archaea have histone-like proteins). Plasmids are extra-chromosomal DNA. Eukaryotic DNA is linear and complexed with histones. This difference is fundamental in cell classification.
