A critical feature of DNA is the ability of the nucleotides to make specific pairs: . Adenine pairs with Thymine and Cytosine pairs with Guanine. The human genome of Homo sapiens is stored on 23 chromosome pairs. 22 of these are autosomal chromosome pairs, while the remaining pair is sex-determining. The haploid human genome occupies a total of just over 3 billion DNA base pairs that means 6 billion base pairs per diploid cell.
Best Answer: I think it is A - The lysosome is a membranous bag which contains hydrolytic enzymes that are used to digest macromolecules. found here: http://library.thinkquest.org/C004535/lysosomes.html.
1 Lysosomes are membrane bound spherical sacs which contain digestive enzymes used to break down materials, such as non-self microorganisms engulfed by Phagocytes. 2  Mitochondria are round double membrane bound organelles responsible for Aerobic Respiration. Chloroplasts contain two fluid separated membranes and the inner membrane is folded into a network of flattened sacs called Thylakoids that are stacked into Grana (one Granum, two Grana). 2  The Thylakoids contain Chlorophyll in which the process of Photosynthesis occurs.
