Genetic analysis

Genetic analysis may be done to identify genetic/inherited disorders and also to make a differential diagnosis in certain somatic diseases such as cancer.

Each molecule of DNA is made from adenine, guanine, cytosine and thymine, which determine what function the genes will possess.

By generating a DNA sequence for a particular organism, you are determining the patterns that make up genetic traits and in some cases behaviors.

Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics.

Karyotyping uses a system of studying chromosomes to identify genetic abnormalities and evolutionary changes in the past.

Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome.

Since an array can contain tens of thousands of probes, a microarray experiment can accomplish many genetic tests in parallel.

One of the most prevalent advancements during the late 20th and early 21st centuries is a greater understanding of cancer's link to genetics.

Research has been able to identify the concepts of genetic mutations, fusion genes and changes in DNA copy numbers, and advances are made in the field every day.

Genetic analysis may be done to identify genetic/inherited disorders and also to make a differential diagnosis in certain somatic diseases such as cancer.

Genetic analyses of cancer include detection of mutations, fusion genes, and DNA copy number changes.
