Study Notes
Cell Types and Genetics
- Germ cells are not somatic cells; they are the reproductive cells that give rise to gametes (sperm or egg cells).
- The human microbiome comprises approximately 30 trillion microbial cells, including bacteria, fungi, and protozoa.
Cell Division
- Meiosis involves two nuclear divisions, resulting in four haploid daughter cells that are genetically unique.
- Mitosis produces two diploid daughter cells that are genetically identical to the parent cell.
DNA and Chromatin
- The human genome refers to the complete set of genes present in a human cell, estimated to be over 20,000 genes.
- Mitochondrial DNA forms circular molecules, not linear molecules.
- Euchromatin is less compact than heterochromatin.
- Chromatin condensation leads to the formation of metaphase chromosomes during the mitotic phase, not interphase.
Genetic Concepts
- A gene encodes a genetic trait, while an allele represents a specific variant of that gene.
- Haploid cells have a single set of chromosomes, whereas diploid cells have two sets of chromosomes.
