Change: : the transfer of genetic material from one microorganism to another by a viral agent (as a bacteriophage).RNA is encoded like DNA, but its general structure is different in several ways. Messenger RNA (mRNA): a copy of a structural gene   View changes from previous version. (Word count: 1906)

Change: hydrogenshydrogen's and an OH group. Deoxyribose differs from ribose in that it lacks an oxygen at carbon 2 (labelled) - and so has only 2 hydrogen atoms (white). Q: What term is defined as a certain segment of DNA   View changes from previous version. (Word count: 1817)

Change: organismorganism.Cell Level: examines the heredity of the cellcell.Chromosome Level: examines the characteristics and actions of chromosomeschromosomes.Molecular Level: deals with the biochemistry of the genesgenes.Genome: the sum total of genetic material of a cellcell.Gene: Fundamental   View changes from previous version.

Change:  Notice the 5 carbon atoms (grey) forming the backbone of the molecule, and the oxygen atom (red) in the ring - which is a 5 sided ring, unlike glucose. The hydrogen atoms (white) are either attached directly to the carbons, or via oxygen as OH groups - at an angle.   View changes from previous version. (Word count: 1831)

Change: deosyribosedeoxyribose sugar, and a nitrogenous base. Nucleotides covalently bond to form a sugar-phosphate linkage that is the backbone of each strand. Each sugar attaches in a repetitive pattern to two phosphates. The nitrogenous bases, purines and pyrimidiens, attach by covalent bonds at the 1' position of the sugar.
