Study Notes
Cell Types
- Ovum (egg cell) is haploid, meaning it contains half the number of chromosomes as a normal cell.
Codons
- A codon is a sequence of three DNA bases that corresponds to a specific amino acid.
Meiosis
- The first meiotic division produces two genetically different daughter cells.
Genetic Terminology
- Allele: One form of a gene.
- Gene: A sequence of DNA coding for a specific protein.
- Chromosome: A long stretch of DNA carrying multiple genes and packaged around histones.
- Chromatin: The cell's genetic material dispersed between cell divisions.
- Genome: All the genetic material within a cell.
- Chromatid: The single strand of a replicated chromosome.
DNA and RNA
- Single-stranded: RNA
- Double-stranded: DNA
- Contains adenine: DNA and RNA
- Contains uracil: RNA
- Contains guanine: DNA and RNA
- Contains thymine: DNA
- Stored in the cell nucleus: DNA
- Translated on the ribosome: RNA
