Levels of Organization
- DNA to RNA to Connexin protein.
- One connexin protein has four transmembrane domains
- 6 Connexins create one Connexon (hemichannel). When different connexins join together to form one connexon, it is called a heteromeric connexon
- Two hemichannels, joined together across a cell membrane comprise a Gap Junction channel.
When two identical connexons come together to form a Gap junction channel, it is called a homotypic GJ channel. When one homomeric connexon and one heteromeric connexon come together, it is called a heterotypic gap junction channel. When two heteromeric connexons join, it is also called a heteromeric Gap Junction channel. - Several gap junction channels (hundreds) assemble within a macromolecular complex called a gap junction plaque.

Famous quotes containing the words levels of, levels and/or organization:
“The country is fed up with children and their problems. For the first time in history, the differences in outlook between people raising children and those who are not are beginning to assume some political significance. This difference is already a part of the conflicts in local school politics. It may spread to other levels of government. Society has less time for the concerns of those who raise the young or try to teach them.”
—Joseph Featherstone (20th century)
“When I turned into a parent, I experienced a real and total personality change that slowly shifted back to the “normal” me, yet has not completely vanished. I believe the two levels are now superimposed, with an additional sprinkling of mortality intimations.”
—Sonia Taitz (20th century)
“Since wars begin in the minds of men, it is in the minds of men that the defences of peace must be constructed.”
