Quick Answer. Instinct, or innate behavior, is an action that is impulsive or immediate based on a particular trigger or circumstance. Learned behavior is an action that someone learns or develops over time through observation, education, training or experience.
The nuclear lamina is a dense (~30 to 100 nm thick) fibrillar network inside the nucleus of most cells. It is composed of intermediate filaments and membrane associated proteins. Besides providing mechanical support, the nuclear lamina regulates important cellular events such as DNA replication and cell division.Additionally, it participates in chromatin organization and it anchors the nuclear pore complexes embedded in the nuclear envelope.he nuclear lamina is assembled by interactions of two lamin polypeptides in which the Î±-helical regions are wound around each other to form a two stranded Î±-helical coiled-coil structure, followed by a head-to-tail association of the multiple dimers.
The Nuclear Envelope is a double layered membrane that surrounds the nucleus. It consist of nuclear pores that regulate the transportation of substances such as RNA into and out of the nucleus. The nuclear envelope consists of an outer nuclear membrane and an inner membrane.he nucleus is known as the information storage organelle. it is enclosed by a double membrane- nuclear envelope. Inside of the nucleus there is DNA. The DNA is bound by proteins- chromatin. The dark spot of the nucleus is the nucleolus-site or rRNA synthesis.
