Genome Entry 1

CHAPTER 1
Chromosome 1

Life Ridley talks about the DNA and RNA. He refers to Genesis and compares the beginning of the world to the beginning of the word. The word represents RNA. RNA is distinguishable different from DNA. He also compares DNA to written languages. He says that it is written in a line where it must be read from side to side. It cannot be read from top to bottom only from either left to right or right to left. He also says that DNA is like the alphabet and although it only has 22 letters, the letters still all represents something. RNA came before DNA and it is more chemically active compared to DNA. However, compared to DNA, it is also more unstable because it is only one strand, unlike DNA which is two strands that complete each other. DNA, compared to RNA, is faster, more reliable, and more accurate which is why organism now have DNA instead of just RNA.
