Document Summary

The structure of nucleic acids (chapter 5: nucleic acids are linear polymers of nucleotides, a nucleotide monomer consists of: The dna double helix (chapter 5: a chromosomal dna molecule consists of two dna strands spiraled around an imaginary axis, forming a double helical structure. In unicellular organisms, division of one cell reproduces the entire organism: multicellular organisms depend on cell division for: Development from a fertilized egg (in sexual reproduction) or a single clonal cell (in asexual reproduction) Maintenance and repair of tissues: cell division is an integral part of the cell cycle, the life of a cell from formation to its own division. Cellular organization of genetic material: a cell"s total co(cid:374)te(cid:374)t of dna is called its ge(cid:374)o(cid:373)e, the genomes of eukaryotic organisms are contained in their nuclear dna. A eukaryotic organism that has just one set of chromosomes in its non- reproductive cells (not all eukaryotes have reproductive cells) is referred to as being haploid.
