Study Notes
Chromosomal Structure and Function
- Centromere provides an attachment point for the segregation of duplicated chromosomes.
Discovery of DNA Structure
- James Watson and Francis Crick described the DNA double helix.
Chromosome Composition
- The region near the chromatin where it is less condensed is most likely to contain the highest density of genes.
Nucleolus Function
- The nucleolus is the site of rRNA synthesis and ribosome assembly.
Gene Definition
- A gene is a sequence of DNA that contains the information required for making a particular functional RNA or protein.
DNA Amplification
- PCR (Polymerase Chain Reaction) is the technique whereby DNA is amplified.
Human Chromosomal Makeup
- A somatic cell of a human biological male has 46, XY chromosomes.
Chromosomal Protein Function
- Histone proteins form a structure that protects and organizes DNA in chromosomes.
Eukaryotic Genome Structure
- Telomeres are found at the ends of eukaryotic genomes, protecting them from deterioration.
Chromosomal Analysis
- Karyotyping refers to the process of preparing and analyzing a visual representation of an individual's chromosomes.
