كروموسوم 3 Chromosome 3، هو واحد من 23 زوج من الكروموسومات البشرية. عادة ما يمتلك البشر زوجان من هذا الكروموسوم. يحتوي الكروموسوم 3 على 200 مليون زوج قاعدي (مادة بناء الدنا) ويمثل حوالي 6.5% من إجمالي الدنا في الخلايا.


نظراً لاختلاف المناهج التي يستخدمها الباحثون في التنبؤ بعدد الجينات في كل كروموسوم، فهناك تباين في أعداد الجينات المقدرة. على الأرجح يحتوي الكروموسوم 2 ما بين 1.100 و1500 جين.

Cytogenetic band

G-banding ideograms of human chromosome 3
G-banding ideogram of human chromosome 3 in resolution 850 bphs. Band length in this diagram is proportional to base-pair length. This type of ideogram is generally used in genome browsers (e.g. Ensembl, UCSC Genome Browser).
G-banding patterns of human chromosome 3 in three different resolutions (400,[5] 550[6] and 850[3]). Band length in this diagram is based on the ideograms from ISCN (2013).[7] This type of ideogram represents actual relative band length observed under a microscope at the different moments during the mitotic process.[8]
