Eagle Pass is the fastest route between San Antonio and Mexico and is often referred to as La Puerta de Mexico or Mexico's Door. It is also the home to the historic ruins of the 18th century San Bernardo Mission.
Lesson Summary. The nucleoid region is the irregularly-shaped section of a prokaryotic cell where DNA is housed. It lacks the membrane that is found around the nucleus of eukaryotic cells. In addition to DNA, the nucleoid may also contain RNA, proteins, and enzymes that can be used for cellular processes.
Eukaroyotic cells also have a variety of organelles that carry out different functions. Prokaryotic cells came before eukaryotic cells so they do not have the organelles that eukaryotic cells have. Eukaryotic cells have a membrane bound nucleus, while prokaryotic cells store the DNA in a region called the nucleoid. Prokaryotic cells also have the outermost layer, the capsid, while eukaryotoic cells do not have this layer.
