Solutions
Expert Solution
1. A. Genetic material composed of nucleic acid . Bacteria are prokaryotes which possess cell wal, and other cytoplasmic components and enzymes required for their metabolism. Virus are classified under different category . They lack cell wall and other cellular machinaries , They lack cellular metabolism . The virus possess only have a protein coat and genetic material composed of nucleic acid. Bacteria also possess circular genetc material which is composed of nucleic acid. Both does not have independent existence they cause infection only after invading on tisdue or only multiply and invade if the condition favourable for them are provided.
2. Developmental homology. Option D.
Developmental homology refers to ancestral evidence. At certain stage of life the organism exhibit partial or complete features that relate to its common ancestry. When similarities exist between ancestry and organism on the base of genes it is genetic homology . If these similarities are based on structure it is tructural homology.
3. PCR.
Polymerase chain reaction. It is usedto amplify single copy of genes into multiple copies for various examination . It is specific method for identification of DNA or gene of intrest. Electrophoresis is a method used for differentiating protein, genomic sequence. Etc based on size , charge etc. GMOs are genetic modified crops which is made by recombination process. CRISPR is a genome editing technologiy.
