Report Abuse. The National Football League (NFL) pays referees anywhere from $25,000 to $70,000 per season. When you consider that the league plays 16 games and referees are considered part-time employees, you get a better sense of the disparity.But do not feel so bad for them, not only are there only 16 games in the schedule, they also get one-week intervals..hen you consider that the league plays 16 games and referees are considered part-time employees, you get a better sense of the disparity.

The ribosome (/ËraÉªbÉµËzoÊm/) is a large and complex molecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules.he ribosome is a cellular machine which is highly complex. It is made up of dozens of distinct proteins (the exact number varies a little bit between species) as well as a few specialized RNA molecules known as ribosomal RNA (rRNA).
Ribosomes are found in the cytoplasm of a cell. They are either free floating or bound to the endoplasmic reticulum. Groups of ribosomes stuck together are called polysomes. Most cells contain thousands of ribosomes, while a few specialized cells contain millions. Brain cells and the cells of the pancreas contain large concentrations of ribosomes since they produce a large amount of protein. slide 2 of 6. The Structure of Ribosomes Although ribosomes are called organelles, they don't have a membrane that holds the contents of the ribosome in one cohesive structure. Ribosomes are composed of ribosomal RNA (rRNA) and protein. Sixty percent of the structure is rRNA and 40 percent is protein. There are two subunits: a large subunit and a small subunit. They are labeled as 60s and 40s after the Svedberg values. The subunits of ribosomes are produced in the nucleolus, which is located in the nucleus of the cell. Ribosomal proteins enter the nucleolus and combine with four rRNA strands to produce the two subunits. The subunits leave the nucleus through the nuclear pores and combine in the cytoplasm.
