Study Notes
Genetics Overview
- Genetic modification involves altering gene sequences by changing the nucleotide base order.
- Genetic testing identifies the presence or absence of mutations linked to specific diseases.
Genome
- The genome is the complete set of genetic material within an organism.
Genes
- Genes are segments of DNA that encode proteins and determine traits.
- Each gene provides instructions for protein synthesis through codons.
- Traits inherited from one generation to the next are managed by genes, a process called inheritance.
- Phenotype refers to observable traits and characteristics of an organism, while genotype denotes the genetic constitution.
- Alleles are variations of genes; for example, the gene influencing eye color can have variations such as 'a' (blue, recessive) or 'A' (brown, dominant).
- Genetic mutations affecting sex cells can be passed down to offspring.
Codons
- RNA is structured from sequences of nucleotides, organized into groups of three known as codons.
- Codons are responsible for coding specific amino acids.
- Amino acids are the building blocks of proteins, crucial for various biological functions.
