Transfer RNA. Small RNA molecules that carry amino acids to the ribosome for polymerization into a polypeptide. During translation the amino acid is inserted into the growing polypeptide chain when the anticodon of the tRNA pairs with a codon on the mRNA being translated.mall RNA molecules that carry amino acids to the ribosome for polymerization into a polypeptide.

According to the US Census Bureau, the average salary in America is $35,000. Assuming this average remains the same throughout the average working career of 40 years, as a rough way to consider the impact of inflation, then the average American would earn $1,400,000 in their lifetime. Most analysis tools use average household income, which is approximately $51,000.
Either way, we have you covered. In the September 2014 Census Bureau report on income and poverty in the U.S., the median household income in America across all jobs was $51,939. That reflects 2013 information; 2014 data will be out in September of this year. That figure was not statistically different from 2012, reflecting continually stagnant wages.
