What is meant by Metacentric?
1 : of or relating to a metacenter. 2 : having the centromere medially situated so that the two chromosomal arms are of roughly equal length.
What is the function of metacentric chromosome?
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.
What is metacentric and acrocentric chromosomes?
Metacentric: when the two chromosome arms are equal in length. Submetacentric: when the two chromosome arms are unequal in length, e.g. shorter p arms and longer q arms. Acrocentric: when the p (short) arm is too short to observe but is still present.
What is meant by Metacentric chromosomes?
n. A chromosome with a centrally placed centromere that divides the chromosome into two arms having approximately equal length.
What is meant by metacentric height?
: the distance of the metacenter above the center of gravity of a floating body.
What is the feature of Metacentric?
Metacentric chromosome has centromere in the middle and its two arms (chromatids) are almost equal in length.
Where is Metacentric chromosome found?
Metacentric chromosomes have the centromere located midway between the ends of the chromosome, separating the two arms of the chromosome (Figure 1). Chromosomes with centromeres positioned visibly off-center are called submetacentric.
What is the main function of centromere?
The primary function of the centromere is to provide the foundation for assembly of the kinetochore, which is a protein complex essential to proper chromosomal segregation during mitosis.
Which chromosomes are acrocentric chromosome?
In humans, chromosomes 13, 14, 15, 21, and 22 are acrocentric, and all of these chromosomes are associated with Robertsonian translocations.
What is Acrocentric centromere?
: having the centromere situated so that one chromosomal arm is much shorter than the other.
