Study Notes
- Genetics is the study of trait inheritance from one generation to the next.
- Genes are the basic unit of heredity, passed from parent to child.
- Genes dictate the development of different characteristics.
- The two major subdivisions of genetics are molecular and Mendelian genetics.
- Molecular genetics studies the molecular structure of DNA, RNA, proteins, and gene function.
- Mendelian genetics studies how physical traits are passed down through generations.
- DNA stands for deoxyribonucleic acid.
- DNA is a molecule composing chromosomes and carrying genetic information.
- Nucleotides are the subunits of DNA.
- A nucleotide contains a sugar (deoxyribose), phosphate, and a nitrogen base.
- The four bases found in DNA are Adenine, Thymine, Guanine, and Cytosine.
- Adenine (A) pairs with Thymine (T) using 2 hydrogen bonds.
- Cytosine (C) pairs with Guanine (G) using 3 hydrogen bonds.
- Purines are Adenine and Guanine.
- Pyrimidines are Thymine, Cytosine, and Uracil.
- DNA contains Thymine, while RNA contains Uracil.
- Nucleotides are held together by N-Glycosidic, Phosphoester, Hydrogen, and Phosphodiester bonds.
- N-Glycosidic bonds link sugar and base.
- Phosphoester bonds link sugar and phosphate.
- Hydrogen bonds connect complementary bases.
- Phosphodiester bonds occur between one nucleotide's phosphate and another's sugar.
- A polynucleotide is a long nucleotide chain forming DNA.
- DNA's shape is a double helix.
