A cell with one set of chromosomes is called A. Alleles B. Diploid C. Haploid D. Homologous E. Sister chromatid 34. Which type of cell divides by the formation of a cleavage furrow? A. Animal B. Bacteria C. Fungi D. Plant 35. What is the inheritance pattern in the pedigree? A. Autosomal recessive B. Autosomal dominant C. X-linked recessive 36. What is the genotype of the female in the last generation of the pedigree? A o. Homozygous dominant C Heterozygous Heterozygous dominant ,Homozygous recessive 37. Extra or missing chromosomes result from B. Synapsis 38. Skin color is determined by an additive effect of multiple genes, meaning that it is an example of , A. Nondisjunction C. Crossing over D. Independent assortment C. Incomplete dominance D. Pleiotropy A. Codominance E. Polygenic inheritance 8. Epistasis 39. Extraterrestrial life visits Earth. Before meeting with them, they give you a sample of something similar to a virus that all of them naturally have on their bodies. The government needs to determine if this new virus is harmful to life on Earth. Your part in the research is to determine what the genetic material of the virus is. You have been told by other researchers that the virus is composed of only two different types of molecules unique to the aliens, which you have decided to call watson and crick Watson contains element X and crick contains element Z. You grow the virus in two different batches, one of radioactive X and one of radioactive Z. You allow viruses from each batch to infect different cell samples given to you by the aliens, blend the samples in a blender, then centrifuge each. In the batch grown in radioactive x, the liquid was not radioactive, but the solid pellet in the tube was radioactive. In the batch grown in radioactive Z, the liquid was radioactive, but the sold pellet in the tube was not radioactive. What viral molecule was injected into the cells, possibly indicating what the genetic material is made of? E. I should have studied more. C. Both D. Neither A. WatsonExplanation / Answer
AS PER CHEGG POLICY, PROCEEDING TO ANSWER ONLY THE FIRST 4 QUESTIONS/SUBPARTS, THAT IS, QUESTIONS 27 TO 30:
ANSWER 27
A. Indel - this is because when a nucleotide is added or removed, the system of reading three at a time changes and all the amino acids thereafter are altered.
ANSWER 28
D. Translocation - the elements themselves are referred to as transposons
ANSWER 29
B. Chromatin - this is because the linear nature greatly aids in greater transcription and translation, while the condensed nature is more useful for periods of division.
ANSWER 30
D. Cohesin - These are proteins that form rings that keep two identical pieces of DNA together
