INTRODUCTORY INFO In all living organisms, genetic material is mainly made up of molecules of a nucleic acid called DNA- deoxyribonucleic acid. Genetic material is like an instruction manual that: Controls the processes needed to build and make the cell work.
Provides the guidelines for each call type to coordinate with one another to build a fully operational multicelular organism.

every At the onset of embryonic development, ale celes

distinct process of cell differentiation and develops into
Each of these cele

various cell types because each ce type follows different instructions from the

Human body cells acquire different characteristics because they follow different instructions within the same

chemical structure of the DNA Molecule
DNA molecules consist of two very long strands of nucleotides twisted together, forming
spring called a double helix.
DNA strands contain four types of nucleotides, each with a
different nitrogenous base:
Granire& complementary bases
The two strands are twisted thanks to the attractive forces hydrogen bonds, that
the boses on one strand of DNA evert on the other. Hydrogen bonds any form
