Proteins are used for all kinds of structure and function inside cells. Proteins make up structural molecules such as the cytoskeleton that allow cells to move, grow, divide and keep a specific structure to do their job in the body. Proteins also make up enzymes, that perform all the ...

The PcG and TrxG proteins are recruited to cis-regulatory elements called Polycomb/Trithorax response elements (PREs). The PcG and TrxG proteins act antagonistically through PREs to maintain silent and active gene expression states, respectively. These states are initiated by transcription factors that...
What are formed elements of blood?BloodThe blood is the plasma and cells that travel throughout the body. The blood provides the organs and tissues of the body with essential substances such as sugars, oxygen and hormones. The blood also transports waste such as carbon dioxide out of the ...
Think about this, while proteins are migrating through the polyacrylamide matrix, the leading edge is encountering smaller pore sizes than the lagging edge. That means that the leading edge is passing through the gel at a slightly slower pace compared to the lagging edge. So, the band sort of...

Proteins Using the text book, you have 5 minutes to find and write down notes on: What elements are present in proteins? Which element is ESSENTIAL to build proteins Where do (i) plants (ii) animals get this element from? What are the main uses of proteins?
Lumbar puncture(spinal tap) is often considered to evaluate the cerebrospinal fluid (CSF) for infection, bleeding, or abnormal proteins, depending upon the clinical situation. Blood tests are usually performed to explore any illnesses that can also involve the brain....

One of the principal elements ofthe difference between short-term and long-term memoryis that long-term memory stores information we are likely to need again in the future. Gut feelings arise from that well of information collected over our lifetimes. When the brain sends stress signals to the...
