Bio 150 Final Exam - UTK Mamantov(2024 LatestWhat statement best distinguishes scientific hypotheses from scientific theories? - ANSWER Hypotheses are usually narrower in scope; theories have broader explanatory power. A controlled experiment ____________. - ANSWER includes at least two groups, one of which does not receive the experimental treatment In trying to determine whether DNA or protein is the genetic material, Hershey and Chase made use of which fact? - ANSWER DNA contains phosph...

Electron Transport Chain (ETC) Four protein complexes in the inner mitochondrial membrane form the electron transport chain. -Here the electron carriers come along to drop off all their electron and proton cargo that they picked up during the glycolysis and citric acid cycle stages. - NADH + H+ and FADH2 become oxidized, donating electrons to the first and second protein complex respectively. The independent variable in an experiment is the one thing that is varied between experimental grou...

AP Biology: Unit 6 Exam Questions With Correct Answers 100% Verified. What is the structure of DNA? - answerMolecules called nucleotides, each nucleotide has a phosphate group, sugar group, and a nitrogen base. Its made up of 2 strands forming a double helix Role of Alfred Hershey and Martha Chase in discovering the structure of DNA - answer- Alfred Hershey and Martha chase performed experiments showing that DNA is the genetic material of a phage known as T2 -They designed an experiment ...

Hershey and Chase performed an experiment in order to determine how bacteriophages infect bacteria. What did they find? The bacteriophage injects DNA into the host cell. This was found because, after centrifugation, the pellet was radioactive The largest difference between a Gram + and Gram - bacterial cell is: The gram + cell has a much thicker peptidoglycan layer Why does a Gram + cell stain blue/purple in a gram stain? The Gram + cell stains blue/purple because crystal violet rem...

The scientist (scientists) that confirmed DNA was the genetic information by working with bacteria that infect viruses is (are): ~ Hershey and Chase Rosalind Franklin ~ Used X-ray diffraction to discover the double-helical structure of DNA. Genotype vs. Phenotype ~ By genetic, within me, you cant see vs. my physical appearance A trait that is controlled by many genes is referred to as What? ~ Polygenetic Griffith Transformation Experiment ~ mixed heat-killed S with live R an...

What is the structure of DNA? CORRECT ANSWER Molecules called nucleotides, each nucleotide has a phosphate group, sugar group, and a nitrogen base. Its made up of 2 strands forming a double helix Role of Alfred Hershey and Martha Chase in discovering the structure of DNA CORRECT ANSWER -Alfred Hershey and Martha chase performed experiments showing that DNA is the genetic material of a phage known as T2 -They designed an experiment showing only 2 components of T2 (DNA or protein) enters an E....

What statement best distinguishes scientific hypotheses from scientific theories? - ANSWER Hypotheses are usually narrower in scope; theories have broader explanatory power. A controlled experiment ____________. - ANSWER includes at least two groups, one of which does not receive the experimental treatment In trying to determine whether DNA or protein is the genetic material, Hershey and Chase made use of which fact? - ANSWER DNA contains phosphorus, whereas protein does not. In analyzi...

Friedrich Miescher - discovered DNA in 1869 But did not know (Isolated phosphate) rich acidic compounds Frederick Griffith - Discovered transformation during an experiment that involved injecting mice with smooth S cells, rough R cells, heat-killed S cells, and heat-killed S cells with living R cells. Avery, MacLeod, McCarty - Identified the heritable substance as DNA Used test tubes- vitro Hershey and Chase - performed experiments showing that DNA is the genetic material of a phage known...

Two sources of variability that arises during meiosis and fertilizations - 1. Crossing over 2. Independent Assortment Crossing Over - homologous chromosomes pair... each sister chromatid consists of a single stranded DNA molecule What is the result of the crossing over between homologous chromatids? - The exchange of segments Where do the homologous chromosomes separate? - First meiotic division What is produced after meiosis II - two daughter chromosomes have parental combinations of al...

When T.H. Morgan's group showed that genes are located on chromosomes, the two components of chromosomes-_____ and _____-became candidates for the genetic material. correct answers DNA; proteins How was the role of DNA in heredity discovered? correct answers By studying bacteria and the viruses that infect them Griffith's experiment Overview correct answers An experiment carried out by Griffith using the heat-killed bacteria in mice to discover that a factor in heat-killed, disease-c...
