Ch 17 Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ____ 1. Garrod hypothesized that "inborn errors of metabolism" such as alkaptonuria occur because a. genes dictate the production of specific enzymes, and affected individuals have genetic defects that cause them to lack certain enzymes. b. enzymes are made of DNA, and affected individuals lack DNA polymerase. c. many metabolic enzymes use DNA as a cofactor, and affected individuals have mutations that prevent their enzymes from interacting efficiently with DNA. d. certain metabolic reactions are carried out by ribozymes, and affected individuals lack key splicing factors. e.

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.

Acclimatization - short-term, reversible responses to environmental fluctuations // phenotypic change in an individual in response to short-term changes in the natural environment. The ability to acclimatize is itself an adaptation. As an individual develops, the embryonic tissues give rise to four adult tissue types: 1. Connective tissue loose connective tissue - fibrous proteins in a soft matrix; serves as a packing material b/w organs or padding under the skin (ex: reticular connective tissue in lymphoid organs such as the spleen and bone marrow/ adipose tissue or fat tissue are loose connective tissues made up of cells suspended in a matrix of fibers and fluid) dense connective tissue - found in tendons and ligaments that connect muscles, bones,

The Evolution of Psychology Psychology is an ancient art ?psyche? = soul ?logos? = study of a subject And a less ancient scientific discipline early 18th century - ?study of the mind? Multi-disciplinary approaches: Room for chemists, biologists, physiologists, sociologists, anthropologists, evolutionary everythingists, etc. Intellectual parents - philosophy and physiology And Wilheim Wundt, the godfather United all the different questions under one common mystery umbrella 1870 - first lab founded in University of Leipzig The Early Growth Phase Thanks to Wundt, started off on a good science foot. Scientific study of conscious experience: Attention Sensation and perception Reaction time etc.

Chapter 14 #5 A black guinea pig crossed with an albino guinea pig produces 12 black offspring. When the albino is crossed with a second black one, 7 blacks and 5 albinos are obtained. What is the best explanation for this genetic situation? Write genotypes for the parents, gametes, and offspring Answer Albino (b) is a recessive trait; black (B) is dominant. First cross: parents BB ? bb; gametes B and b; offspring all Bb (black coat). Second cross: parents bb ? Bb; gametes 1/2 B and 1/2 b (heterozygous parent) and b; offspring 1/2 Bb and 1/2 bb #6

Genetics Problems 1. A rooster with gray feathers is mated with a hen of the same phenotype. Among their offspring, 15 chicks are gray, 6 are black, and 8 are white. What is the simplest explanation for the inheritance of these colors in chickens? What offspring would you predict from the mating of a gray rooster and a black hen? 2. In some plants, a true-breeding, red-flowered strain gives all pink flowers when crossed with a white-flowered strain: RR (red) x rr (white) ---> Rr (pink). If flower position (axial or terminal) is inherited as it is in peas what will be the ratios of genotypes and phenotypes of the generation resulting from the following cross: axial-red (true-breeding) x terminal-white? What will be the ratios in the F2 generation?

Chapter 15 The Chromosomal Basis of Inheritance Overview: Locating Genes Along Chromosomes Mendel?s ?hereditary factors? were genes, though this wasn?t known at the time Today we can show that genes are located on chromosomes The location of a particular gene can be seen by tagging isolated chromosomes with a fluorescent dye that highlights the gene Concept 15.1: Mendelian inheritance has its physical basis in the behavior of chromosomes Mitosis and meiosis were first described in the late 1800s The chromosome theory of inheritance states: Mendelian genes have specific loci (positions) on chromosomes Chromosomes undergo segregation and independent assortment The behavior of chromosomes during meiosis was said to account for Mendel?s laws of segregation and independent assortment
