What are 5 proteins that are made by ribosomes

The ribosome has two subunits; a smaller one and a bigger one. The smaller one contains 21 proteins and one rRNA molecule, and the larger subunit contains 34 proteins and two rRNA molecules. Ribosomes are found in prokaryotes and eukaryotes (although they are a little different, they have the same function). Ribosomes are made of nucleolus. Some people might think that mRNA also helps to form the structure of the ribosome, but this is not the case. rRNA makes up the ribosome of a cell, while mRNA travels to the ribosome of a cell during protein synthesis in order to code for the amino acids. Only during protein synthesis will the mRNA appear in a ribosome. mRNA does not make up the structure of the ribosome! Hope this helps! RNA and proteins

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
