Organisms inherit specific traits and characteristics form their parents

genes

Explanation:

Genes are a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

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."

creative diagnostics provides a protocol for total protein extraction based on ripa which is widely used.
