Need some help with the topic: amino acids. Here are the questions.

What does it mean when scientists say that living organisms share a universal genetic code?
How does a universal genetic code relate to the hypotheses about the origin of life on Earth?
How are self-replicating molecules, such as RNA molecules in the “RNA World” hypothesis, essential to the most popular hypotheses about the origin of life on Earth?
How might similarities and differences in genetic codes, or the proteins built as a result of these codes, be used to determine how closely related different sp

Do you about the sequence of events that take place for the synthesis of a protein? that is, DNA -transcription-> mRNA -translation-> protein If you dont, then reading about would be a good place to start. If you do know about this, then, read about molecular clocks, http://evolution.berkeley.edu/evosite/evo101/IIE1cMolecularclocks.shtml

Molecular clocks might be a bit further than he needs to go for that last question.

Thank you guys. I'm still a little confused so I'm going to leave the question open until the assignment is finished. Thanks again.

What are you confused about?

"until the assignment is finished" ...are you going to be posting your answers here for us to review?
