Chapter 18, Problem 7TYU
FOCUS ON INFORMATION
The continuity of life is based on heritable information in the form of DNA. In a short essay (100-150 words), explain how mutations in protein-coding genes and regulatory DNA contribute to evolution.

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.

- To explain: The extraordinary mutation resistance of the genetic code argues in favor of its origin as a frozen accident or as a result of natural selection.arrow_forward51.arrow_forwardBeadle and Tatum's experiments led to the "one gene - one enzyme (protein)" hypothesis. In subsequent years, many exceptions to this hypothesis were noted. A molecule of hemoglobin fails to support this hypothesis for which of the following reasons? n eukaryotes, one gene can code form multiple isoforms of a polypeptide. The functional hemoglobin protein is made from multiple polypeptides. Not all enzymes are proteins. Not all genes encode proteins.arrow_forward

- Intro. Medical microbiologists believe that overuse of antibiotics in animal feed may select for antibiotic resistant bacteria which subsequently can be passed on to humans, potentially causing infection by these antibiotic resistant bacteria. This is an example of : Biological evolution by natural selection O Enzymes which cause really high mutations rates in the bacterial DNA drugs acting as mutagens Phenotypic drift caused by random mutationsarrow_forwardHow does Epigenetic connect to unifying themes and principles of biology? (Give 2 examples)arrow_forwardWhich statement about the central dogma is FALSE? It is about the flow of genetic information. It is an outdated theory that is no longer relevant. Transcription and translation are the two steps that facilitate the flow of genetic information. The sequence of DNA specifies the sequence of mRNA, which then specifies the sequence of amino acids in the polypeptide chain.arrow_forward
- Which of the following statements about mutations are true? * Mutations are always passed down to future generations. Mutations decrease the genetic diversity of organisms. Mutations occur only in somatic cells since they are diploid. Mutations are changes in the phosphate backbone of DNA which always have harmful effects. Mutations always cause a frameshift. Mutations can be harmful, neutral, or beneficial to the organism. Mutations are changes in the nucleotide sequence of a DNA molecule. Mutations may cause a change in the protein sequence resulting from the genetic code for that gene.
