BIOL 1202 : BIOL 1202 Exam 1
Document Summary
Homo sapiens: upper case first word, italicized. Artificial selection: selected the phenotypes and separated them. 60 million years ago, first primates evolved: today we see their ancestors (us, chimps, bonobos, gorillas) Homo sapiens share dna sequence with every living thing on the planet. Every species uses dna as genotype (not viruses) to make rna, then uses that rna to make proteins. Dna > rna >to make protein (central dogma of biology) gene: segment of dna located at a particular place on a chromosome (locus) Dna codes for specific amino acid sequences in a protein or for the rna that helps make protein. Cells need o2, h2o, and energy source (glucose) to maintain homeostasis, if they lose this, could die. Dna vs. rna: dna, double-stranded, deoxyribose thymine, rna, single-stranded, ribose, uracil, mrna, trna mrna, a,g,u,c messenger rrna trna, ribosomal, read mrna, aug start codon, met first amino acid, transfer, anti codon on one side, amino acid on other.
