Study Notes
DNA Structure and Function
- DNA: Molecule storing genetic information.
- Chromosome: Structure of tightly packed DNA and proteins, containing genes; found in the nucleus, organizing and storing genetic information.
- Gene: Segment of DNA that instructs protein or trait formation.
- Genome: Complete set of an organism's DNA, including genes and non-coding sequences.
- Genotype: Genetic makeup (e.g., BB, Bb, bb) of an organism.
- Allele: Version of a gene that dictates a trait.
- Homozygous: Two identical alleles (e.g., AA or aa).
- Heterozygous: Two different alleles (e.g., Aa).
Protein Synthesis
- mRNA (messenger RNA): Carries genetic code from DNA to ribosomes for protein synthesis.
- tRNA (transfer RNA): Transports amino acids to ribosomes during translation.
- Transcription: DNA to mRNA.
- Translation: mRNA to proteins.
- Ribosome: Cell structure that builds proteins by reading mRNA and connecting amino acids.
Cellular Processes and Genetics
- Autotroph: Organism producing its own food.
- Heterotroph: Organism consuming other organisms for food.
- Histones: Proteins packaging and organizing DNA into chromosomes.
- Haploid: Cell with half the usual number of chromosomes.
- Diploid: Cell with two sets of chromosomes (one from each parent).
- Mitochondria: Cell organelle producing energy through cellular respiration.
- DNA Polymerase: Enzyme copying DNA accurately during replication.
- RNA Polymerase: Enzyme transcribing DNA into RNA for protein synthesis.
- Meiosis: Cell division producing four unique gametes.
- Mitosis: Cell division producing two identical cells.
- Nucleus: Cell control center, housing DNA.
- Homolog: Similar chromosomes from each parent, pairing during meiosis.
- Ortholog: Genes in different species evolved from a shared ancestor, typically with the same function.
- Zygote: Fertilized egg cell.
Inheritance and Genetics
- Dominant: Allele expressing trait even with one copy.
- Recessive: Allele needing two copies to express trait.
- Genetic Recombination: DNA exchange between homologous chromosomes during meiosis; increases genetic variation.
