IB Biology HL Topic 7 Latest 2024 Graded A DNA structure antiparallel strands, 3'-5' linkages, and H bonding between purines and pyrimidines Nucleosomes consist of DNA wrapped around 3 histone proteins and are held together by another histone protein Nucleosomes help to supercoil chromosomes and help to regulate transcription Unique (single-copy) genes are translated and constitute a surprisingly small proportion of eukaryotic DNA Highly repetitive sequences constitute 5-4...

1. replication of material: amount must double through division of both daughter cells (mitosis) + gametes (meiosis) 2. Storage of info: nucleus is the library or repository where genes may be checked out for use or stay on shelves 3. expression of info: DNA - transcription to either mRNA, rRNA, or tRNA - ribosome - translation - protein 4. variation through mutations: evolution 4 things the genetic flow of materials is dependent on 2. advantageous; poor health consequences; adva...

TEST BANK FOR Campbell Biology 9th Edition Glossary A 5′ cap - A modified form of guanine nucleotide added onto the 5′ end of a pre-mRNA molecule. A site - One of a ribosome's three binding sites for tRNA during translation. The A site holds the tRNA carrying the next amino acid to be added to the polypeptide chain. (A stands for aminoacyl tRNA.) ABC hypothesis - A model of flower formation identifying three classes of organ identity genes that direct formation of the four types of f...
