Define  Metacentric , Telocentric ?

Dear Student

​​​​​​Based on the position of centromere within the chromosome and length of chromosome arms, chromosomes are categorised as
  • Metacentric
  • Sub-metacentric
  • Acrocentric
  • Telocentric
Metacentric : In this chromosome, centromere is just located at the centre. Therefore, the two arms of chromosomes are equal in length.
It generally looks like 'X' shaped and during cell division in anaphase stage, it appears in the 'V' shape.

Telocentric: In this chromosome, centromere is located at the terminal end, due to which only one arm is present. Ends of these chromosomes are called as telomeres.
It appears rod shaped during anaphase and has only one chromatid.
These definitions will get more clear with this picture,

METACENTRIC
These are X-shaped chromosomes, with the centromere in the middle so that the two arms of the chromosomes are almost equal. A chromosome is metacentric if its two arms are roughly equal in length.
TELOCENTRIC
 A chromosome like a straight rod with the centromere in terminal position. chromosome - a threadlike strand of DNA in the cell nucleus that carries the genes in a linear order; "humans have 22 chromosome pairs plus two sex chromosomes"​​​​​​​.....

Metacentric-
1.centromere is located at the centre of the chromosme
2.the two chromatids are of equal lengths
3. the chromosome appears V shaped during anaphase

Telocentric-
1. centromere is located at the the tip of the chromosme
2. has only one chromatid
3. appears rod shaped during anaphase
