Unit 1 AOS 1 – How do cells function? Chapter 4 Flashcards
asexual reproduction
a method of reproduction that produces genetically identical cells without the fusion of gametes (sex cells)
Binary Fission
the method of cell replication used by prokaryotes
plasmid
a small, circular loop of DNA that is separate from a chromosome
cytokinesis
the division of the cytoplasm and formation of two daughter cells
septum
a dividing wall formed during binary fission
interphase
the first stage of the eukaryotic cell cycle which involves cellular growth and duplication of chromosomes. Composed of three phases: G1, S, and G2
chromosome
a structure composed of DNA tightly wrapped around histone proteins. Carries the genetic information (genes) of a cell
mitosis
the second stage of the eukaryotic cell cycle, which involves the complete separation of sister chromatids and nuclei
sister chromatids
the two identical halves of a replicated chromosome
cytokinesis
the division of the cytoplasm and formation of two daughter cells
chromatin
chromosomes (DNA and proteins) that have been unwound and loosely packed during interphase
