Differences Between Cytogenetics and Molecular Genetics
Differences Between Cytogenetics and Molecular Genetics is given below:
| Feature | Cytogenetics | Molecular Genetics |
|---|---|---|
| Focus | Study of chromosomes and their structure, number, and behavior | Study of genes at the molecular level, including DNA sequence and function |
| Techniques | Karyotyping, fluorescence in situ hybridization (FISH), comparative genomic hybridization (CGH), G-banding | Polymerase chain reaction (PCR), DNA sequencing, gel electrophoresis, gene cloning |
| Visualization | Microscopic examination of chromosomes | Analysis of DNA, RNA, and protein sequences |
| Scope | Chromosomal abnormalities, such as aneuploidy, translocations, deletions, and duplications | Gene mutations, expression patterns, genetic coding, and regulatory sequences |
| Applications | Prenatal diagnosis, cancer cytogenetics, genetic disorder identification, karyotype analysis | Genetic testing, gene therapy research, understanding genetic diseases, personalized medicine |
| Resolution | Low to medium resolution; detects large chromosomal changes | High resolution; detects small mutations and variations at the nucleotide level |
| Sample Types | Typically uses cells that are actively dividing, such as blood, bone marrow, or amniotic fluid cells | Can use any biological sample containing DNA/RNA, such as blood, saliva, or tissue samples |
| Outcome | Identifies structural and numerical chromosomal abnormalities | Identifies specific gene mutations and sequence variations |
Cytogenetics – Meaning, History, Techniques, and Application
Cytogenetics is the branch of genetics that studies the structure, function, and behaviour of chromosomes. It involves techniques such as karyotyping, FISH, and CGH to detect chromosomal abnormalities. This field plays a crucial role in diagnosing genetic disorders, cancers, and prenatal conditions.
Cytogenetics combines microscopic and molecular methods to understand chromosomal contributions to disease and development. In this article, we will read about cytogenetics, its application, techniques, importance, and impact on the future, and much more.
