Explain the importance of complementary base pairing to the conservation of the base sequence in DNA. Contrast the structure and function of DNA and RNA. 8. In more detail than #7 above‚ describe the structure of DNA including the antiparallel strands‚ the 3’–5’ linkages‚ and the role of the hydrogen bonding between purines and pyrimidines.

supported by which of the following? Both green algae and plants have chlorophylls a and b and various accessory pigments. Both green algae and plants store excess carbohydrates as starch and have cellulose in their cell walls. Molecular evaluation of ribosomal RNA provides evidence of the evolutionary relationship of plants and green algae. All of the choices are evidence. Which of the following features would have helped early plant ancestors evolve to a terrestrial existence? apical cells cellulose

Prevalence of clarithromycin resistance in H.pylori patients with failure of treatment Introduction; The H.pylori is a gram negative bacterium that colonizes the stomach has a high prevalence; more than 50 percent of the global population has H.pylori. It’s influenced by geography‚ age‚ gender‚ socioeconomic status‚ although it is decreasing in the developed world‚ it remains high in the developing world as there is less proper sanitation and hygiene‚ crowdedness‚ lack of safe water supply

Case Study A 17-year-old female with systemic lupus A 17-year-old female was admitted with a month long history of involuntary movement bilaterally in hand and legs. The patient stated that the movement started one month ago. And she had occasionally involuntary movement of her mouth. The symptoms were mild in the beginning and gradually increased. The patient had dyskinesia around her mouth and thoracic and occasionally choreathetoid movement in bilateral upper extremity. She said she had similar

structures is provided in Table 4.2. Nucleus and Ribosomes The nucleus houses chromatin‚ which contains DNA‚ the genetic material. During division‚ chromatin becomes condensed into chromosomes. The nucleolus is an area within the nucleus where ribosomal RNA is produced. Proteins are combined with the rRNA to form the subunits of ribosomes‚ which exit the nuclear envelope throughnuclear pores. Ribosomes in the cytoplasm synthesize polypeptides using information transferred to the DNA by mRNA. Endomembrane
