What are some of the technical challenges of cloning a mammoth? Check all that are true Ancient mammoth DNA has degraded so it is hard to know the complete genome sequence Mammoth gestation time is likely too short to allowing cloning A living surrogate mother would have to be used, which could pose problems since the closest relative to mammoths is endangered elephants A living oocyte would have to be obtained from an extant species, which could pose problems since the closest relative to mammoths is endangered elephants Mammoths lived so long ago that they used a different genetic code than modern animals There are no enzymes in existence that could ligate together mammoth DNA sequence with elephant sequence Mammoths probably had egg shells, which would be hard to penetrate with a needle

Cloning a mammoth involves using advanced genetic engineering techniques to recreate a living mammoth by manipulating its genetic material. The process faces several challenges, including the extraction of well-preserved DNA from ancient mammoth specimens, reconstructing and modifying the mammoth genome, obtaining viable oocytes (egg cells) from a living species (likely elephants) for cloning, and finding a suitable surrogate mother to carry the cloned embryo to term.The true statements among the given options are:Ancient mammoth DNA has degraded so it is hard to know the complete genome sequence: True. Obtaining intact and well-preserved DNA from ancient specimens is a significant challenge. The degradation of DNA over time, especially in fossils that are thousands of years old, makes it difficult to obtain a complete and accurate genome sequence.A living surrogate mother would have to be used, which could pose problems since the closest relative to mammoths is endangered elephants: True. If cloning a mammoth were attempted, a living surrogate mother would likely be necessary to carry the cloned embryo to term. The closest living relatives to mammoths are elephants, and the use of an endangered species as a surrogate poses ethical and logistical challenges.A living oocyte would have to be obtained from an extant species, which could pose problems since the closest relative to mammoths is endangered elephants: True. To clone a mammoth, a viable egg cell (oocyte) from a living species would be needed for the cloning process. Since elephants are the closest living relatives to mammoths, obtaining oocytes from elephants, which are also endangered, poses challenges.Mammoths probably had eggshells, which would be hard to penetrate with a needle: True. The reproductive biology of mammoths is not fully understood, but it is believed that they likely had eggs surrounded by eggshells. Penetrating such structures with a needle during the cloning process could be challenging.The other statements are false:Mammoth gestation time is likely too short to allow cloning: False. Mammoth gestation time is not necessarily a barrier to cloning. The challenge lies more in obtaining viable oocytes and a suitable surrogate mother.Mammoths lived so long ago that they used a different genetic code than modern animals: False. All living organisms, including mammoths, share the same basic genetic code. The challenge is in obtaining intact DNA from ancient specimens.There are no enzymes in existence that could ligate together mammoth DNA sequence with elephant sequence: False. Enzymes that can manipulate DNA sequences, such as ligases, do exist. The challenge is more related to the degradation and preservation of ancient DNA and the specific techniques required for manipulating it.Following is the true statements:-Ancient mammoth DNA has degraded so it is hard to know the complete genome sequenceA living surrogate mother would have to be used, which could pose problems since the closest relative to mammoths is endangered elephantsA living oocyte would have to be obtained from an extant species, which could pose problems since the closest relative to mammoths is endangered elephantsMammoths probably had egg shells, which would be hard to penetrate with a needle
