APAKAH MAKSUD ACROCENTRIC dalam CORSICA?
Centromere
Centromere adalah bahagian kromosom yang menghubungkan kromatid kakak. Semasa mitosis, serat spindel melekat pada centromere melalui kinetochore. Centromeres mula-mula ditakrifkan sebagai lokus genetik yang mengarahkan tingkah laku kromosom. Peranan fizikal mereka adalah bertindak sebagai tapak perhimpunan kinetochore - struktur multiprotein yang sangat kompleks yang bertanggungjawab untuk peristiwa sebenar pengasingan kromosom - mis. mikrotubules yang mengikat dan memberi isyarat kepada jentera kitaran sel apabila semua kromosom telah menggunakan lampiran yang betul pada gelendong, supaya selamat untuk pembahagian sel untuk terus siap. Terdapat pelbagai jenis centromer. "Point centromeres" mengikat protein spesifik yang mengenal pasti urutan DNA tertentu dengan kecekapan tinggi. Mana-mana sekeping DNA dengan urutan centromere DNA urutannya biasanya akan membentuk centromere jika terdapat dalam spesies yang sesuai. Centromere titik yang paling baik adalah golongan ragi yang tumbuh, Saccharomyces cerevisiae.

Animal Cytology and Evolution
'Uropygialis 3' has eight pairs of acrocentric autosomes. The Y's of the first and
the third species are diphasic metacentrics, while that of Uropygialis 2 is
acrocentric. The latter species carries supernumerary chromosomes in some
individuals.

There are three clear alternative explanations (see Searle, 1986a): (1) The

Figure 12 The normal size of an acrocentric short arm is between half of 18p and
up to the full length of 17p. If the p-arm ofan acrocentric chromosome is longer
than 17p it is a pþ variant; if it is shorter than half the length of 18p it is a p–
variant.
