Q:

What are channel proteins?

A:

Channel proteins are proteins that enable the transportation of certain substances and materials across cell membranes. Channel proteins consist of a wide group of more than 20 different organic compounds and, although they share the umbrella title of channel proteins, these substances play different roles. Channel proteins are formed in long chains of amino acids; the sequence of these chains dictates the function and shape of each channel protein.

Bobcats, or Lynx rufus, are endemic to the North American continent. Highly adaptable, these animals thrive in forests, swamps, deserts, agricultural areas and sometimes even in suburban areas. It is estimated that there are 725,000 to 1,020,000 bobcats in the wild. Its name is based on the appearance of its tail, which looks cut or "bobbed."

Bobcats are rarely seen because they are mostly active at night. As strict carnivores, these fierce hunters prey on rabbits, birds, mice, squirrels and other smaller animals. Once they have spotted their prey, they calculate its exact location, and then leap as long as 10 feet to pounce on top of it to pin it down.

  • Q:

    What is the function of the Golgi body?

    A:

    The Golgi apparatus collects simple chemicals in the cell and assembles them into large, complex structures such as proteins. It also plays a role in the process of simple chemical secretion by forming closed vesicles around the substance to be transported. These vesicles then pinch off from the Golgi apparatus and drift to the cell's plasma membrane where the transported substance is released from the cell.

    How does DNA determine the traits of an organism?

    A:

    The pattern of base pairs in the DNA double helix encodes the instructions for building the proteins necessary to construct an entire organism. DNA, or deoxyribonucleic acid, is found within most cells of an organism, and most organisms have their own unique DNA code. One exception to this is cloned organisms, which have the same exact DNA code as their parents do.

  • Q:

    Why is a ribosome important?

    A:

    A ribosome plays a vital role in protein synthesis, a process by which proteins are produced from individual amino acids. A ribosome is a cytoplasmic granule consisting of RNA and protein. Ribosomes are one of the requirements for the protein synthesis to take place. A ribosome is a tiny particle composed of protein and up to 62 percent RNA.
