1
New cards

dna double helix

basic structural unit of the chromosome comprised of nucleotides

2
New cards

histones

proteins around which dna wraps to form nucleosomes, condensing dna for regulation of gene expression

3
New cards

nucleosomes

dna segment wrapped around histones, fundamental unit of chromatin

4
New cards

chromatin

dna/protein complex forming chromosomes

5
New cards

euchromatin

loosely packed chromatin more accessible for gene expression

6
New cards

heterochromatin

tightly packed chromatin that is less accessible and often inactive

7
New cards

centromere

part of the chromosome where sister chromatids are joined and where spindle fibers attach during cell division

8
New cards

telomeres

repetitive dna sequences at the end of chromosomes that protect the chromosome from degradation and fusion

9
New cards

sister chromatids

identical chromosome copies joined at the centromere after dna replication but separated in mitosis
