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.
This means that ribosomes in prokaryotic cells are free-floating in the cytoplasm. In eukaryotic cells, ribosomes can roam free in the cytoplasm, but they can also be bound to the exterior of the endoplasmic reticulum. Ribosomes can also be found in mitochondria and chloroplasts of eukaryotic cells.nitiation of Protein Synthesis. Ribosomes synthesize proteins in both prokaryotic and eukaryotic cells, but the process is initiated differently in each cell type. In eukaryotic cells, the starter amino acid is methionine rather than the N-formylmethionine used by prokaryotic cells.
