Answer:
DNA carries the genetic information for making proteins. ... The base sequence determines amino acid sequence in protein. Messenger RNA (mRNA) is a molecule which carries a copy of the code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.
<span>One observation would be the physical size of Russia compared to other countries, despite a lack of visible borders from space. In addition, part of Russia's outline would likely be obscured by the various clouds and objects in the stratosphere; this would allow the astronaut to view potential cloud and weather patterns on earth. Also, an astronaut could see outlines of Russia's geography such as mountain ranges.</span>
They are composed of long chains of amino acids.
The building blocks of protein are amino acids. Amino acids are organic molecules made up an alpha (center) carbon atom which is linked to an amino group, a carboxyl group, a hydrogen atom and a variable component known as a side chain.
Amino acids are joined to each other by peptide bonds to form either a short chain called an oligopeptide or a long chain called a polypeptide. These chains are what forms the protein.
<span>The lymphoid tissues of the intestinal tract are collectively referred to as GALT.Gut-associated lymphoid tissue (GALT) is a component of the mucosa-associated lymphoid tissue (MALT) which works in the immune system to protect the body from invasion in the gut.</span>
