Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

If all living organisms have the same pattern, then humans would have the same genetic code as a worm because all species have the same repeated pattern, DNA could not provide the variety needed for the genetic code.

It was proven to be false because…”)
The Selfish Gene is a radical theory that argues that all living creatures are essentially vehicles for their genes- hence, we all are a “survival machine" for our genes. In the light of what you have learned about the molecular structure and function of the gene, is this perspective still relevant? Cite specific biological phenomena to prove your point. References:

In the new paradigm, biology is a science based on three levels of molecular information: Biology is a science of information: starting from discovery of DNA and the genetic code, now biologists study how that information is stored, how it is used, and how it evolves. Biologists can take advantage of the same molecular tools to analyze different biological systems, comparing and contrasting the details of information storage and processing that information. Level 1. genetic information is encoded in DNA. Level 2. Biological information is embodied in proteins. What is Level 3? _______________________________ Give your explanation. ____________________________________
What is the purpose of a molecular clock?
Human DNA contains almost twice as much information as is needed to code for all the substances produced in the body. Likewise, the digital data sent from Voyager II contained one redundant bit out of every two bits of information. The Hubble space telescope transmits three redundant bits for every bit of information. How is entropy related to the transmission of information? What do you think is accomplished by having so many redundant bits of information in both DNA and the space probes?
