What are Cellular Channels?
Cellular channels are hydrophilic pores across membranes which are formed by channel proteins and mediate passive transport of solutes by forming an aqueous diffusion pore.
What is Carrier Mediated Membrane Transport?
Carrier mediated membrane transport is a cellular transport mechanism that is mediated by carriers. Carriers are membrane transport proteins which are involved in the movement of ions, small molecules, and macromolecules, across the cell membrane.
What is Passive Membrane Diffusion?
Passive membrane diffusion is a type of membrane transport that does not require energy to move substances across cell membranes.
What is the Plasma Membrane?
The plasma membrane is the membrane found in all cells that separates the interior of the cell from the external extracellular environment.
What is Cellular House Keeping?
Cellular house-keeping are activities which take place at specific sites in the cell that control local signaling such as protein signaling. Housekeeping genes are typically expressed because they are essential to a cell survival. These cellular house-keeping activities take place…
What is Long Noncoding RNA (lncRNA)?
Long Noncoding RNA (lncRNA) are transcripts more than 200 nucleotides long that is not translated into protein. Long noncoding RNA can modulate chromatin structure, function, and the transcription of neighboring and distant genes. Long noncoding RNA can also affect RNA…
What is MicroRNA?
MiroRNA (miRNA) is a small single-stranded non-coding RNA molecule about 22 nucleotides long which to control the amount of making of proteins in the cell.
What is RNA?
Ribonucleic acid (RNA) is single stranded molecule which has function to convert information stored in DNA to proteins.
What are Chromatin Organizing Factors?
Chromatin organizing factors: histone chaperones, histone modifying enzymes and ATP-dependent chromatin remodeling complexes.
What is DNA Methylation?
DNA methylation results in methyl groups being added to the DNA molecules at C5 position of cytosine to make it 5-methylcytosine. DNA methylation regulates gene expression by inhibiting the binding of transcription factors to DNA.
