What is one of the contributions made to the development of the microscope by galileo?

1.first to document careful observations of different cell types
2.identifying the first cell
3.used mathematics to improve the focus of the lens
4.created the first microscope
5.discovered the electron microscope
6.built microscopes capable of magnification of up to 1250 x using regular light

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
