Study Notes
Chromosomes and Cells
- Chromosomes are usually found in the nucleus of a human cell.
- All human cells, except for red blood cells, contain chromosomes.
Autosomal Function
- Autosomal chromosomes, which are non-sex chromosomes, determine the characteristics of an individual, excluding sex.
DNA
- DNA stands for Deoxyribonucleic acid.
Protein Synthesis
- Protein synthesis takes place in the ribosomes, which are found in the cytoplasm of a human cell.
Haploid and Diploid
- A haploid is a cell that contains only one set of chromosomes.
- Diploid cells, on the other hand, contain two sets of chromosomes, one inherited from each parent.
Zygote and Gamete
- A zygote is a fertilized egg that contains genetic material from two parents, whereas a gamete is a reproductive cell, such as a sperm or an egg, that contains only half of the genetic material.
Natural Selection
- Natural selection promotes the survival and reproduction of individuals with favorable traits, leading to the adaptation of a species to its environment.
Phenotype
- A phenotype is the physical and behavioral expression of an individual's genetic makeup, which is influenced by environmental factors and genetic code.
