ANT100Y1Y Outline for EVOL ANTH Lecture #2
Understand microevolution: Understand macroevolution:
Genetic basis of inheritance and biological Speciation, how evolution works on grand scale, &
evolution, population genetics, natural selection, &ern synthesis.
The Modern Synthesis of Evolution
Genetics, Chromosomes, & DNA Molecules
DNA & Protein Production
Synthesis of single strand of ribonucleic acid (mRNA: messenger RNA) at unwound section of DNA
with one of DNA strands serving as template. Result: genetic information encoded in DNA transferred
to RNA. mRNA carries information into cytoplasm.
tRNA (transfer RNA) is information adapter molecule. Direct interface between amino-acid sequence
of protein & information in mRNA. Decodes information in mRNA. Acceptor stem where specific
amino acid is attached. Anticodon reads information in mRNA sequence by base pairing.
Genetics & Heredity
Gene Alleles Dominant alleles
Phenotype Homozygous Recessive alleles
