Document Summary
Two complementary nucleotides in an rna or a dna molecule that are held together by hydrogen bonds. Orderly sequence of events by which a cell duplicates its contents and divides into two. Specialized dna sequence that allows duplicated chromosomes to be separated during m phase; can be seen as the constricted region of a mitotic chromosome. Complex of dna and proteins that makes up the chromosomes in a eukaryotic cell. Chromatin-remodeling complex enzymes that uses the energy of atp hydrolysis to alter the arrangement of nucleosomes in eukaryotic chromosomes, changing the accessibility of the underlying dna to other proteins, including those involved in transcription. Long threadlike structure composed of dna and proteins that carries the genetic information of an organism; becomes visible as a distinct entity when a plant or animal cell prepares to divide. Describes two molecular surfaces that fit together closely and form noncovalent bonds with each other.
