1. Griffith's experiments with heat killed pathogenic bacteria and live non-pathogenic bacteria indicated something from the dead bacteria could do something to the living, non-pathogenic bacteria that he called transfor- mation. What changes were observed in colony appearance and pathogenic- ity?: When the heat-killed S cells were mixed with the living R cells they combined and formed living S cells- smooth encapsulated cells 2. What biological macromolecule did Avery, McCarty, and MacLeod i...

A/T = C/G D. A - C = T - G - ANSWER B. C + G = A + T A controlled experiment.... A. Includes at least two groups, one of which does not receive the experimental treatment. B. Proceeds at a slow pace to guarantee that the scientist can carefully observe all results. C. Includes at least two gro...

Biology ABCTE Certification Test Part 1genetic drift - correct answer The following phenomena affect Hardy-Weinberg equilibrium. Which one is associated with small populations and chance changes in allele frequency? allantois - correct answer Which embryonic membrane develops into the umbilical cord in placental mammals? separation of homologous chromosomes during meiosis - correct answer Mendel observed that pea color was a characteristic passed independently of flower color. What caus...

Largest to Smallest - Genome > Chromosome > Chromatin > DNA > Genes > Nucleic Acid DNA Polymerase III - synthesizes new DNA only in the 5' to 3' direction Leading Strand - has one primer Lagging Strand - has multiple primers Griffith - pathogenic pneumonia cells were able to transform non-pathogenic cells Chargaff - base composition varied from species to species and A-T and C-G complementation Hershey and Chase - concluded that the genetic material of the bacteriophag...

What cellular events occur in the G1 phase of the cell division cycle? - ANSWER normal growth and cell function What is the best way to describe homologous chromosomes? - ANSWER they carry information for the same traits In some parts of Africa, the frequency of individuals who are heterozygous for the sickle-cell anemia allele is higher than the frequency in North America, presumably because this reduces the frequency of malaria. Such a relationship is related to what? - ANSWER Darwin's ...

Proteins- four things they do correct answers -building blocks for cell structures - form enzymes that catalyze chem reactions - regulate the activity of genes - enable cell to move and communicate junk dna correct answers dna that encodes for information not needed in the cell When can chromosomes be seen clearly correct answers during cell division Cell Division is the most.....need what? correct answers ...important bio. process, but you need a blueprint for daughter cells (inheri...

BIO 111 TAMU Fletcher Exam 3 Questions and Answers 100% Solved 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 e...

What cellular events occur in the G1 phase of the cell division cycle? - normal growth and cell function What is the best way to describe homologous chromosomes? - they carry information for the same traits In some parts of Africa, the frequency of individuals who are heterozygous for the sickle-cell anemia allele is higher than the frequency in North America, presumably because this reduces the frequency of malaria. Such a relationship is related to what? - Darwin's theory of natural sel...

What is the reason that closely linked genes are typically inherited together? - ANSWER The likelihood of a crossover event between these two genes is low All female mammals have one active X chromosome per cell instead of two. What causes this? - ANSWER Activation of the XIST gene on the X chromosome that will become the Barr body In his transformation experiments, what did Griffith observe? - ANSWER Mixing a heat-killing pathogenic strain of bacteria with a living nonpathogenic strain ca...
