The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group. There are four different types of nucleotides found in DNA, differing only in the nitrogenous base. Adenine and guanine are purines. Purines are the larger of the two types of bases found in DNA. Cytosine and thymine are pyrimidines. DNA is a normally double stranded macromolecule. RNA is single stranded. Two polynucleotide chains, held together by weak thermodynamic forces, form a DNA molecule. The DNA backbone is a polymer with an alternating sugar-phosphate sequence. The deoxyribose sugars are joined at both the 3'-hydroxyl and 5'-hydroxyl groups to phosphate groups in ester links, also known as "phosphodiester" bonds. 5.  Which of the following is not found in a DNA? a. Adenine b. Guanine c. Cytosine d. Uracil Please provide appropriate updations Ques Which of the following is not found in a DNA? a. b. c. d.

Your Name Please describe the changes made by you   This Question is based on the following passage:   In animals, a substance is released by an endocrine gland into the blood stream, which carries it to remote sites in the body. This substance is called a hormone. Hormones in animals coordinate body functions by being produced in one place and acting in another. Insulin is a protein hormone of vertebrates. It affects the amount of glucose in the blood. It is secreted by the B- cells of islets of Langerhans. An endocrine gland which is attached to the floor of the brain of all craniate vertebrates and which is responsible for a number of hormones is called the pituitary gland. Thyroid is an endocrine gland of vertebrates. It secrets iodine containing hormones (thyroxine and thyroglobulin). A trace of iodine in the diet is necessary to supply the thyroid and. 9.  Where are the B- cells of islets of Langerhans which secrete insulin located? a. Stomach b. Liver c. Pancreas d. Gall Bladder Please provide appropriate updations Ques Where are the B- cells of islets of Langerhans which secrete insulin located? a. b. c. d. Your Name Please describe the changes made by you   This Question is based on the following passage:    Living organisms (e.g. some bacteria and fungi, glow-worms and many marine animals) produces the creations of light of various colors. Luminescence is produced by a biochemical reaction, which is catalyzed by an enzyme. In some animals the light is used as a mating signal; in others it may be a protective device. In deep-sea forms luminous organs may serve as lanterns. 10.  How is the light produced in living organisms? a. By a biochemical reaction b. By a photochemical reaction c. By an organ of the body d. By the food eaten Please provide appropriate updations Ques How is the light produced in living organisms? a. b. c. d. Your Name Please describe the changes made by you   This Question is based on the following passage:   The immune system is a complex organ, which is highly specialized cells and a circulatory system separated from blood vessels. The organs of the immune system, positioned throughout the body, are called lymphoid organs. The word "lymph" in Greek means a pure, clear stream. Lymphatic vessels and lymph nodes are the parts of the special circulatory system that carries lymph, a transparent fluid containing white blood cells, chiefly lymphocytes. Lymph bathes the tissues of the body, and the lymphatic vessels collect and move it eventually back into the blood circulation. Lymph nodes dot the network of lymphatic vessels and provide meeting grounds for the immune system cells that defend against invaders. The spleen, at the upper left of the abdomen, is also a staging ground and a place where immune system cells confront foreign microbes. Pockets of lymphoid tissue are in many other locations throughout the body, such as the bone marrow and thymus. Tonsils, adenoids, Peyer's patches, and the appendix are also lymphoid tissues. Both immune cells and foreign molecules enter the lymph nodes via blood vessels or lymphatic vessels. All immune cells exit the lymphatic system and eventually return to the bloodstream. Once in the bloodstream, lymphocytes are transported to tissues throughout the body, where they act as sentries on the lookout for foreign antigens. 11.  How do the immune cells and foreign molecules enter the lymph nodes? a. Via Blood vessels b. Via Lymphatic vessels c. Via Digestive system d. None of the above Please provide appropriate updations Ques How do the immune cells and foreign molecules enter the lymph nodes? a. b. c. d. Your Name Please describe the changes made by you   This Question is based on the following passage:   Recent studies suggest that traces of persistent chemicals may cause permanent changes in children, resulting in lower IQ levels, attention deficits and other behavioral problems. Researchers say this new data marks a paradigm shift in the way toxic chemicals may be regulated, as scientists begin linking broad human health effects to small doses of chemicals in the environment. Eating organic food may help to better promote cellular health since several agricultural chemicals used in the conventional growing of foods have been shown to have a negative effect on mitochondrial function. Several chemicals including paraquat, parathion, dinoseb, and 2-4-D have been found to increase cell membrane permeability exposing the mitochondria to damaging free radicals, inhibiting a process known as coupling that is integral to the efficient production of adenosine triphospate (ATP). ATP is an important cellular chemical that bonds at nerve terminals for normal neural communication. The low levels of cellular ATP at nerve terminals may lead to the loss of synapses and synaptic function, and may ultimately lead to cognitive decline. A child's developing nervous system is more at risk than an adult's. 12.  A low levels of cellular ATP at nerve terminals may lead to which of the following problems? a. Mental disorder b. Loss of synapses and synaptic function c. Downs Syndrome d. Klienfelters syndrome Please provide appropriate updations Ques A low levels of cellular ATP at nerve terminals may lead to which of the following problems? a. b. c. d.
