Question

28) le M ore Ullowing experiments transformation C) UV light mutation experiment B) Yeast Complementation experiment D) Transduction experiment 26) It red-colored flowers (Rare dominant over white colored flowers and wrinkled seeds (Ware dominant over smooth seeds, then the genotype RRww would appear as A) red, smooth ) white, smooth mooth red, wrinkled red, wrinkled D) white,wrinkled 29) Which of the following techniques is commonly used by Csi agents to solve crime, paternity cases, and identify victims, by matching human body tissue to the individualit came from? A) Phage Transduction B) DNA fingerprinting C) Bacterial transformation D) Bacterial conjugation 29) 30) 30) What is the name of the most simple technique that separates DNA fragments by their size? A) Conjugation B) Restriction enzymes C) Centrifugation D) Gel electrophoresis TRUE FALSE. Write T if the statement is true and F if the statement is false. 31) The genotype is the physical appearance of a trait. RR w Rw Rw w Rw Ru 32) Gel electrophoresis is used to cut DNA at specific locations. 33) DNA fingerprinting utilizes DNA regions that is highly variable between individuals. 34) Progeny from cross: AA x aa has a uniform genotype and phenotype. 35) Most body fluids contain DNA. 36) Polymerase Chain Reaction Technique is used to amplify a specific regions of DNA. 37) In gel electrophoresis, shorter DNA fragments travel shorter distances. 38) A pedigree is a tool used to examine mode of inheritance of a genetic disorder in a human family. 39) Plasmid is a circular molecule of DNA found outside the bacterial chromosome. 40) The purpose of Bacterial transformation is to change the genetic makeup of bacteria. 41) In an allele for tall (T) is dominant to an allele for short (t), half of the progeny will be tall in TTxTt. 42) Specific DNA fragments can be identified with labeled probes.

Answer 1

28) RRww, is homozygous for the dominant allele R and homozygous for the allele w so the phenotype is red flowers and smooth seeds so the answer is A) red, smoothe.

29) DNA fingerprinting is a technique by which the minisatellites in the genome, DNA fingerprinting is used in the paternity test, to find the victims so the answer is B) DNA fingerprinting

( all three other are process by which bacteria get an extrachromosomal DNA, conjugation is the process by which DNA is transferred from one bacteria to another via sex-pili, DNA is transferred to bacteria by bacteriophages is called transduction, and bacteria take up the DNA from the environment is called transformation )

30)gel electrophoresis is the process by the DNA fragments are separated through the agarose gel using the electric field, DNA is negatively charged, when the electric field is applied the DNA moves through the small pores in the gel, so the smaller fragments move faster and larger fragments move slowly through the gel so the answer is D) gel electrophoresis

(conjugation is the process by which DNA is transferred from one bacteria to another via sex-pili, restriction enzymes cut the DNA at specific sequences)
