    Study Notes

    Introduction to Genetics

    • Genetics is the science of the 20th century that began with the discovery of Mendel's laws in 1900.
    • In 1906, William Bateson coined the term "genetics" and wrote the first book on the subject.

    DNA Structure and Function

    • DNA is composed of nucleotides, which are made up of a sugar molecule, a phosphate molecule, and one of four nitrogenous bases (A, C, G, and T).
    • The nucleotides are arranged in a double helix structure, with two strands twisted together.
    • The DNA molecule is found in the nucleus of eukaryotic cells and cannot leave the nucleus.
    • The genetic information in DNA is used to synthesize proteins.

    Gene Expression and Protein Synthesis

    • Gene expression is the process by which the information in DNA is used to create a protein.
    • The process of gene expression involves transcription (DNA to RNA) and translation (RNA to protein).
    • During transcription, one of the DNA strands is used as a template to create a complementary RNA molecule (mRNA).
    • The mRNA molecule leaves the nucleus and travels to the ribosomes in the cytoplasm, where it is translated into a protein.
    • The sequence of amino acids in the protein is determined by the sequence of nucleotides in the mRNA.

    Functions of DNA

    • DNA stores genetic information in the form of genes and genomes.
    • DNA is responsible for the transmission of genetic traits from one generation to the next.
    • DNA is involved in the regulation of gene expression, including the activation and repression of genes.

    Classification of Primates

    • Primates are mammals that belong to the order Primates.
    • The traditional classification of primates includes the suborders Strepsirrhini and Haplorhini.
    • The classification of primates is based on their shared characteristics and evolutionary relationships.

    Australopithecines

    • Australopithecines are a group of early human ancestors that lived around 4 million years ago.
    • They are characterized by their bipedalism, but they do not belong to the genus Homo.
    • They retain primitive characteristics typical of monkeys.

    Foundations of Behavioral Genetics

    • Behavioral genetics is the study of the genetic and environmental factors that influence behavior.
    • The field of behavioral genetics aims to understand the complex interactions between genes and environment that shape behavior.
    • The study of genetics and behavior is important for understanding human behavior and developing treatments for behavioral disorders.
