Nuclear membrane

Nucleur envelope

An essential component of metazoan cells. Next to providing mechanical support to the Nucleus, its involved in most nuclear activities including: DNA replication, DNA repair, RNA transcription, chromatin organization, cell cycle regulation, cell development and differentiation, nuclear migration, and apoptosis. Its composed of intermediate filaments and membrane associated proteins.

Plant Cell Nuclear Membrane

A diagram of the anatomy of the cell. Clearly labeled and colored so that the students can distinguish individual parts. High cognitive level.

During prophase the nucleus and nuclear membrane both disappear and now there are two sister chromatids and the centromes are moving to opposite sides !!!

Animal Cell.

It is structural and functional unit of all living organisms. It is composed of cytoplasm and nuleus enclosed by cell membrane.cell are of different shapes and sizes. It consist of cytoplasm and nucleus.The cell Structure consists of cell membrane Cytoplasm and Nuleus

Prokaryotic cells are unicellular organisms without a nuclear membrane. Certain cell organelles like mictochondria, lysosomes are absent in prokaryotes.

The nuclear envelope is perforated with tiny holes known as nuclear pores, which were first discovered in the mid-twentieth century. These pores regulate the passage of molecules between the nucleus and cytoplasm, permitting some to pass through the membrane, but not others.

Understanding nuclear membrane function in a cell will help us to become more aware about the crucial role it plays in functioning of our bodies. This BiologyWise article tells you how the nuclear membrane functions in a cell.

Proteins targeted for transport to the Golgi apparatus are transferred from ribosomes on RER into the RER lumen- which serves as the site of protein folding in sacs (cisternae) modification, and assembly. Synthesized proteins in vesicles are transported to the Golgi apparatus.

Structure and function of endoplasmic reticulum is important for the cell to carry out its proper functioning.What is endoplasmic reticulum?Endoplasmic reticulum stands for "endoplasm" meaning “the inner portion of cytoplasm” and "reticulum" meaning “network”. The Endoplasmic reticulum was first detected in the cell by Garnier in 1897. Under a microscope, there is a network of interconnected membrane-bounded channels extending from the cell membrane to the nuclear envelope.Structure and…

The main difference between glycolipid and glycoprotein is that glycolipid is a carbohydrate-attached lipid whereas a glycoprotein is a carbohydrate-attached protein. Functionally, glycolipids facilitate cellular recognition while glycoproteins serve as receptors for chemical signals.

Many cellular activities are controlled by post-translational modifications, the study of which is hampered by the lack of specific reagents due in large part to their ubiquitous and non-immunogenic nature. Creative Biolabs has developed High-Affi™ technology, which offers antibody discovery services that specific for post-translational modifications on proteins.

endoplasm reticulum's function is to move the proteins made by the Ribosomes

The endoplasmic reticulum or ER is a maze of parallel membranous tubules and flattened sacs surrounding the nucleus that connects with the nuclear membrane and runs throughout the cytoplasm. ER with ribosomes attached is called rough endoplasmic reticulum and is involved in protein synthesis, production of new membrane, modification of nascent proteins, and transport of these proteins and membrane to other locations within the cell. ER without ribosomes is called smooth endoplasmic…
