Study Notes
DNA Structure and Processes Summary
- DNA loops are 50,000-100,000 base pairs in length and are stabilized by cohesin.
- Histone code involves histone tails that can be tagged by methyl, acetyl, phosphate, and other groups.
- Different enzymes, such as histone methyltransferase and histone acetyltransferase, modify histones through methylation and acetylation.
- Chromatin can be either heterochromatin, highly compacted, or euchromatin, loosely packed diffuse chromatin.
- DNA can be repeated, non-repeated, tandemly repeated, or interspersed repeated, with different lengths and arrangements.
- The nucleus contains the nuclear envelope, nuclear pores, nucleoplasm, nuclear localization signals, nuclear matrix, nuclear lamina, and nucleolus.
- Mitosis involves nuclear division and cytokinesis, while replication includes processes like semi-conservative replication, replication forks, replicons, and origins of replication.
- DNA replication requires various enzymes such as DNA polymerase, primase, helicase, exonucleases, and endonucleases.
- Mutations can be spontaneous, due to environmental agents, or caused by specific processes such as tautomers and trinucleotide repeats.
- DNA repair mechanisms include photoreactive repair, base excision repair, nucleotide excision repair, nonhomologous end-joining, and homologous recombination.
- Transcription involves RNA synthesis using DNA as a template, while translation is the synthesis of proteins using information in the RNA.
- Genetic code is based on a set of rules that relate DNA base sequences to the linear order of amino acids in protein products and involves genes, triplet code, and indel mutations.
