Chapter 5 Vocab Flashcards
a multi-subunit enzyme complex that changes the accessibility of DNA to other proteins
chromatin remodeling complex
the total genetic information carried by a cell or an organism
genome
the genetic material formed of DNA and protein and observed between periods of cell devision in eukaryotic cells
chromatin
the specific DNA sequence where DNA replication begins
replication origin (origin of replication)
a double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell’s proteins
DNA
the basic, beadlike unit of DNA packaging in eukaryotes
nucleosome
any of several threadlike structures consisting of chromatin, that carry the genes in a linear order
chromsome
capable of precisely base-pairing with one another by matching G with C and A with T
complimentary
one of many discrete units of hereditary information located on the chromosome and consisting of DNA
gene
small portions with a high proportion of positively charged amino acids that bind to the negatively charged DNA and play a key role in its folding into chromatin
histone
arranged in parallel but with opposite orientations like the two strands of the DNA double helix
antiparallel
non-transcribed eukaryotic chromatin that is so highly compacted that is visible with a light microscope during interphase
heterochromatin
the end of a chromosome. receptive DNA sequences here help conserve chromosome tips
telomere
two nucleotides paired by hydrogen bonds such as A-T or C-G
base pair
the characterization of the chromosome complement of an individual or a species, including number, form, and size of the chromosomes; typical chromosome map
karyotype
