16 - The Molecular Basis of Inheritance Ch. 16: The Molecular Basis of Inheritance Concept 16.1: DNA is the genetic material Early in the 20th century, the identification of the molecules of inheritance loomed as a major challenge to biologists When T. H. Morgan?s group showed that genes are located on chromosomes, the two components of chromosomes?DNA and protein?became candidates for the genetic material A chromosome consists of a DNA molecule packed together with proteins The bacterial chromosome is a double-stranded, circular DNA molecule associated with a small amount of protein Eukaryotic chromosomes have linear DNA molecules associated with a large amount of protein In a bacterium, the DNA is ?supercoiled? and found in a region of the cell called the nucleoid

A major technological advancement in the 1950?s that changed culture was the development of the hydrogen bomb by the U.S. and later the USSR. This discovery created an atmosphere of fear of nuclear annihilation and resulted in an arms race. Each country fought to create bigger and better bombs and delivery systems. Public service announcements prepared the world for a nuclear war in which both nations would face large-scale, probably suicidal, retaliation strikes. Movies such as Godzilla came to feature monsters mutated by nuclear testing. Movements were founded to fight for global disarmament.

Ch 16 Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ____ 1. For a couple of decades, biologists knew the nucleus contained DNA and proteins. The prevailing opinion was that the genetic material was proteins, and not DNA. The reason for this belief was that proteins are more complex than DNA. This is because a. proteins have a greater variety of three-dimensional forms than does DNA. b. proteins have two different levels of structural organization; DNA has four. c. proteins are made of 20 amino acids and DNA is made of four nucleotides. d. Only A and C are correct. e. A, B, and C are correct. ____ 2. In his transformation experiments, Griffith observed that a.

What are the two chemical components of chromosomes? DNA and protein 2. Why did researchers originally think that protein was the genetic material? Until the 1940s, the case for proteins seemed stronger, especially since biochemists had identified them as a class of macromolecules with great heterogeneity and specificity of function, essential requirements for the hereditary material. Moreover, little was known about nucleic acids, whose physical and chemical properties seemed far too uniform to account for
