Use the results of the gel electrophoresis to:Part A: Identify which of the four known species is most closely related to the newly discoveredspecies of fish.Part B: What characteristics of each species led to the decision?Part C: Explain how the relatedness of the fish species can be determined by examining wherethe bands are located in the electrophoresis gel. Scientists discovered a new species of fish. Using gel electrophoresis, they analyzed samples ofDNA from the new species and from four known fish species. The figure below shows the bandsof fish DNA from the gel electrophoresis.GEL ELECTROPHORESIS RESULTSFROM FIVE SPECIES OF FISHNewSpeciesKnown Known KnownSpecies Species SpeciesAKnownSpeciesBCDKEYBands in the Gel

aterials Spirochaetes are free-living, anaerobic bacteria that contain spiral-shaped cells. Nematodes are roundworms that are incredibly diverse and, as a group, have adapted to survive in all environments. Which of the following statements accurately describes the DNA of both groups? * pdates ades embers nferences The spirochaete genome is smaller than the nematode genome. Q Online Nematode DNA is circular. sela Spirochaete chromosomes are composed of just DNA while nematode chromosomes also include specialized proteins. on Periods 1 and 2 eriods MP1, Highschool chool MP3, Spirochaete DNA is linear.

A researcher used polymerase chain reaction (PCR) to test four individual nematodes for the presence of a mutation in Gene Y. When amplified, the fragments of DNA containing the mutated gene alleles were 250 base pairs long and the normal (wild type) alleles were 350 base pairs long. To identify the genotypes of the individual nematodes, the researcher used gel electrophoresis to visualize the PCR results. 1.000 bp 500 bp 300 bp 200 bp 100 bp Remember that these nematodes are diploid organisms and as such, inherited two copies of Gene Y. Which of the following statements is a correct analysis of these results a) Nematode As homozygous for this gene and has two copies of the mutated allele. O b) Nematode C is heterozygous for this gene and has one copy of the mutated allele and one copy of the normal (wild type) allele.
