- What can result in a point mutation in cells that are produced by mitosis or meiosis? an error during DNA replication an error in proofreading processes an error in translationFigure 1.7 Decide if each of the following is an example of inductive or deductive reasoning. All flying birds and insects have wings. Birds and insects flap their wings as they move through the air. Therefore, wings enable flight. Insects generally survive mild winters better than harsh ones. Therefore, insect pests will become more problematic if global temperatures increase. Chromosomes, the carriers of DNAr separate into daughter cells during cell division. Therefore, each daughter cell will have the same chromosome set as the mother cell. Animals as diverse as humans, insects, and wolves all exhibit social behavior. Therefore, social behavior must have an evolutionary advantage.When doing a lab that involves Extraction of Genomic DNA from adult Drosophila melanogaster. - What are the controls you should use and why use these? What is special about the genomic DNA? What do you expect to find (using these genomic DNA samples)? please help!
- Use the simple flow chart below to outline the basic procedure of genetic engineering in six steps make sure that your answers are in form of short sentences or clauses with complete thoughtBase on Carl woese' ribosomal RNA (rRNA) gene tree. How can I map the following traits: 1.Monolayer lipid membrane 2.Linear chromosomes 3.Gram-negative cell wall 4.Several RNA polymerase 5.DNA 6.Glycerol 7.70s ribosomes 8.Nucleus To Carl's gene tree (bacteria,Archae,Eukarya).A couple attends a medical consultation for infertility problems and repetitive abortions. The doctor suspects that the problem is due to a mutation, that is why he requires a study in which chromosomes can be visualized, and which reflects if there are any alterations in structure and number. What procedure could he use to obtain this information? Group of answer choices Hydrolysis Locus Karyotype In vitro fertilization The upper extremities of the whale, the bat, the cat, the horse and the man, fulfill in some the function of fins to swim, in others the function of wings to fly, and legs or arms in the case of the man, but all of them maintain the same structure with the same number of bones. This allows us to identify a common ancestor in these groups. What evidence of evolution does the example refer to?
