(you know the answer, whether you know it or not)
“All matter tends toward lowest energy and highest disorder”
Q. What is life?
A. Information which uses captures energy to battle the second law of
thermodynamics
Thinking about the human genome
•3.2X109 bp
•If each base were one mm long…
•2000 miles, across the center of Africa

Thinking about the human genome•3.2X109 bp
•If each base were one mm long…
•2000 miles, across the center of Africa
•Average gene about 30 meters long
•Occur about every 270 meters between them
•Once spliced the message would only be ~1meter long

Table 17.1 Types of RNA in a Eukaryotic Cell
3 Types of RNA
Messenger RNA (mRNA)- carries information to be translated into amino acid sequences to the ribosome
Ribosomal RNA (rRNA)- the working “spine” of the ribosome
Transfer RNA (tRNA)- the “decoder keys” that will translate nucleic acids to amino acids.
