ANT 301 Lecture Notes - Lecture 3: Miosis, Dna Replication, Cell Nucleus
Document Summary
Dna does not provide exact details of what happens to the information carried. **terms to know: traits, genes, genotype, phenotype, dominance. Mitochondria is the powerhouse of the cell, it has its own dna. Adenine, guanine, cytosine, thymine (all of them bound with weak hydrogen bonds) *genetic info nucleus must duplicate itself to pass onto other cell. Dna unzips, then other parts come to ll in the. Explains why you"re not identical to your siblings. Mitosis -> dna -> unzips, transcription (rna synthesis) -> mrna -> ribosome (where protein is) Dna is transcribed into mrna in the cell nucleus. Mrna is processed and introns are snipped out, exams spliced together. Mrna moves out of nucleus to the ribosome. **dread recipe -> transcription to translation -> make food. Intron segments of dna between eons, that are transcribed to rna but removed before translation. Variation in protein synthesis arises by changing what introns are snipped.
