Study Notes
Chromatin
- Composed of DNA and proteins, forming the structure of chromosomes.
- Found in clusters within the nucleus, containing DNA, RNA, and proteins.
Histone
- Proteins that DNA coils around, influencing DNA structure.
- Facilitate the DNA's arrangement either in a loose, uncondensed form or in compact x-shaped chromosomes.
- Crucial for maintaining chromosome shape and enabling efficient packing of DNA.
Replication
- Refers to the process through which a cell duplicates its DNA.
- Essential for cell division and ensuring genetic information is transmitted accurately to daughter cells.
DNA Polymerase
- Enzyme that plays a critical role in DNA replication.
- Responsible for linking individual nucleotides to form a complementary DNA strand.
DNA Replication Process
- Initiates with the separation of the DNA molecule into two strands.
- Each original strand serves as a template to create two new complementary strands.
- The process adheres to the base pairing rules, ensuring accurate replication of the genetic material.
