Eras

Science / Biology / Eras: One of the major divisions of the geologic time scale.

Polymerase Chain Reaction (PCR)

Science / Biology / Polymerase Chain Reaction (PCR): A method of amplifying or copying DNA fragments that is faster than cloning. The fragments are combined with DNA polymerase, nucleotides, and other components to form a mixture in which the DNA is cyc MORE

Electrical Erasable Programmable Read Only Memory (EEPROM)

Technology / Computers / Electrical Erasable Programmable Read Only Memory (EEPROM): Electrical Erasable Programmable Read Only Memory. This type of memory can be reprogrammed and erased electronically repeatedly by using a device programmer which provides an electric surge. This memo MORE

Cholinesterase Inhibitors

Business / Agriculture / Cholinesterase Inhibitors: A class of chemicals that includes numerous insecticides, such as parathion or carbaryl. They inhibit an enzyme found in animals that regulates nerve impulses. Cholinesterase inhibition is associated MORE

Polymerase (DNA Or RNA)

Science / Genetics / Polymerase (DNA Or RNA): Enzymes that catalyze the synthesis of nucleic acids on preexisting nucleic acid templates, assembling rna from ribonucleotides or dna from deoxyribonucleotides. MORE

Dna Polymerase

Science / Biology / Dna Polymerase: In DNA replication, the enzyme that links the complementary nucleotides together to form the newly synthesized strand. MORE
