Study Notes
- A DNA strand with the sequence AAA-TTT-GGG has a complementary DNA sequence of TTT-AAA-CCC
- The complementary mRNA sequence is UUU-AAA-CCC
- Decoding the mRNA strand AUG-AUU-UUG-GCA-GGC-CAAA-UAA yields the amino acid sequence Start-Ile-Leu-Ala-Gly-Gln-Stop
- The backbone of DNA is composed of sugar and phosphodiester bonds
- The "rungs" of DNA are made of bases
- Translation happens in the ribosome
- Transcription happens in the nucleus
- Uracil is a nitrogen base present in RNA but not DNA
- The different phases of the cell cycle are Interphase, Mitosis, and Cytokinesis
- The different phases of Mitosis are Prophase, Metaphase, Anaphase, and Telophase (PMAT)
- DNA replication occurs during the S phase of interphase
- Prophase is the longest phase of mitosis
- Interphase is the longest phase of the cell cycle
- Be able to identify the different phases of mitosis.
- Types of mutations include missense, nonsense, silence, and frameshift mutations
