Karyotype
- A karyotype refers to the complete set of chromosomes in an organism.
- It is typically organized by size, shape, and number for analysis.
- Used to identify genetic abnormalities, chromosomal disorders, or gender determination.
- Karyotyping is often performed using blood samples, bone marrow, or amniotic fluid cells.
DNA Replication
- DNA replication is the process of producing two identical copies from one original DNA molecule.
- It occurs in the S phase of the cell cycle before cell division.
- Key enzymes include helicase, DNA polymerase, and ligase.
- The process follows a semi-conservative mechanism, where each new DNA molecule consists of one old strand and one new strand.
