This happens very occasionally. The main reason is that the cells are taking a bit longer to grow in culture. Just like we all show differences in our height or weight, cells can also differ in how quickly they grow. Other times we do not get enough cells to look at initially and we need to grow more. The extra culture time does not mean that there will necessarily be a problem with your result.
Cytogenetics is the study of chromosomes. Karyotyping is used to describe chromosome analysis which checks for the correct number and structure of chromosomes. Chromosomes can only be seen when a cell is dividing and they can be treated to display a banded pattern, similar to a bar code.
We use cytogenetics and karyotyping for testing the following:
DNA (deoxyribose nucleic acid) is life’s genetic code that tells the body how to function or what to look like. The DNA code is made up of 4 different chemical units called bases. The bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The code, if you were to read it, would look something like this:
A gene is a section of genetic code that can be decoded by the cell to mean something. A single gene might be responsible for any aspect of your body's function or appearance, like making a certain protein, or the colour of your eyes.
If there is an error in the code for a gene the product will be faulty. The DNA (genetic code) is packaged into chromosomes inside each cell.
