Study Notes
Genotype and Genetic Terminology
- A genotype refers to the genetic makeup of an organism, encompassing all the alleles present in its DNA.
- It defines the hereditary traits, such as eye color or blood type, that can be passed to offspring.
Role of Messenger RNA (mRNA)
- Messenger RNA (mRNA) serves as a template for protein synthesis, carrying genetic information from DNA to ribosomes.
- mRNA translates genetic codes into proteins, playing a crucial role in gene expression.
Transfer of Genetic Information in Bacteria
- Conjugation is the process by which bacteria transfer genetic material through direct contact, often involving a pilus.
- This horizontal gene transfer allows bacteria to share traits such as antibiotic resistance.
Homologous Chromosomes and Alleles
- Homologous chromosomes are pairs that contain genes for the same traits but may have different versions, known as alleles.
- This genetic variation is essential for evolution and adaptation in populations.
Punnett Square in Genetic Studies
- A Punnett square is a visual tool used to predict the possible genetic combinations from a cross between two parents.
- It illustrates the probability of offspring inheriting specific traits based on the parents’ genotypes, helping to understand inheritance patterns.
