define:1) chromosome (2) centromere (3)neucleosome(4) nucleotides
Answers
CHROMOSOME :
Chromosome 1 is the designation for the largest human chromosome. Humans have two copies of chromosome 1, as they do with all of the autosomes, which are the non-sex chromosomes.
CENTROMERE :
The centromere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids (a dyad). During mitosis, spindle fibers attach to the centromere via the kinetochore.Centromeres were first thought to be genetic loci that direct the behavior of chromosomes.
NEUCLEOSOME :
A nucleosome is a basic unit of DNA packaging in eukaryotes, consisting of a segment of DNA wound in sequence around eight histone protein cores.
NUCLEOTIDE :
a compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.
