Hippocrates
Father of medicine
Beloved that diseases were naturally cases
Aristotle
Models of inheritance
Traits of parents are transmitted from parent to child and can be influenced by the environment
William Harvey
Developed the theory of epigenesis (set the stage for modern embryology )
Body organs are not initially present in the embryo but are formed later
Which two Germans developed the cell theory
Matthias schledian ,and Theodor Schwann
Charles Darwin
His theories suggest that populations evolve over many generations through the process of natural selection
Alfred Russel Wallace

Gregor Mendel
Discovery that traits are passed from parent to offspring In predictable ways
Heredity
The passing of a physical or mental characteristic genetically from one generation to another
Diploid
2n
Mitosis
DNA is duplicated then divided during cell division
Describe cell division in mitosis
Chromosomes of a parent cell are copied and distributed to each daughter cell
The two resulting daughter cells receive a diploid set (2n )
Meiosis
Making egg and sperm cells
Describe the process of meiosis
Chromosomes are copied than distributed twice
Resulting cells only receive half the number of chromosomes
These cells are haploid (n)
DNA is
Hereditary material in eukaryotes and prokaryotes
Responsible for storage and replication of genetic information
Antiparallel strands
Double stranded helix
Made of nucleotides
What is the monomer of DNA
Nucleotide consisting of sugar (deoxyribose )
The sugar is bonded to phosphate
The sugar is also bonded to the nitrogen containing bases (A,C,G,T)
