Which Cell Division Phase is Best for Karyotyping?

Which Cell Division Phase is Best for Karyotyping?

Karyotyping is a process of seeing chromosomes in order to know abnormalities related to it. The metaphase chromosomes are most separatable and visible.  Abnormalities in DNA or chromosomes can cause severe mental, physical or developmental disabilities. In order to find out the alteration related to chromosomes, we have to perform the cytogenetic analysis while to …

Role of colchicine in karyotyping

Colchicine- A Mitotic Inhibitor in Karyotyping

“Mitotic inhibitor halts cell division during karyotyping in order to get separated chromosomes. Colchicine is a common mitotic inhibitor used in cytogenetic techniques like karyotyping.” Cytogenetic techniques are used to study cell and related components. Karyotyping is a method used to analyze chromosomes during cell division hence consider as cytogenetic technique.  To get good chromosomes …

What are Mitogens? How is it Important in Karyotyping?

What are Mitogens? How is it Important in Karyotyping?

“Mitogens are lectins or other peptides that bind to the cell surface and induce mitotic activity and cell division.“ By using the MAPK- mitotic activated protein kinase, a signal transduction pathway induced by mitogens leads to mitosis. The mitogens are potent endogenous or exogenous agents facilitating cell division by increasing mitotic activity.  But what is …

20 Common karyotyping (or Chromosomal) Abnormalities

A karyotype is prepared in order to study the abnormalities associated with it that are commonly known as chromosomal abnormalities or karyotyping abnormalities.  Usually, karyotyping abnormalities are either structural or numerical, notably, here single base change or other smaller alteration related DNA can’t be encountered using the karyotyping.  However, as we know we can count …
