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.
Lysosomes are organelles with various digestive enzymes. These are lysosomal enzymes that are synthesized in the rough endoplasmic reticulum and imported from the Golgi apparatus as vesicles. These enzymes are used primarily for digestion and removal of excess or worn-out organelles, food particles, and engulfed viruses or bacteria.
