Computational Molecular Biology and Genomics:
Molecular Biology Concepts
Familiarity with the following concepts is a prerequisite
for this course. While some of this material will be reviewed
in class, students are ultimately responsible for acquiring any background
knowledge they may be lacking.
Resources
Tree of life
- Prokaryotes,
Eukaryotes
- Eubacteria,
Archaebacteria, Eukaryotes
Proteins
- Amino
acids
- Properties:
hydrophobic, polar, charge, size, acidic, basic
- Protein
sequence:
- Orientation:
C and N terminals
- Backbone, side chains
- Primary,
secondary , tertiary structure
(Modified) Central Dogma
DNA
- Nucleotides:
- Basic
structure: sugar, phosphate, base
- adenine,
thymine, guanine, cytosine
- purines
and pyrimidines
- Watson-crick
pairing
- Double
helix structure
- DNA
replication
- Genomic
versus complementary DNA (cDNA)
RNA
- Differs
from DNA: ribose, uracil, single stranded
- Secondary
and tertiary structure
Genes
- Genetic
code
- Transcription
- Translation
- Regulation
- Differences
between prokaryotes and eukaryotes
- Intron/exon structure
- mRNA, tRNA
- Ribosomes
- Alternative
splicing
Cell organization
- Prokaryotes :
- Typically,
one circular chromosome
- No
nucleus, no organelles
- Eukaryotes:
- Typically,
more than one diploid chromosome
- Nucleus,
organelles (esp mitochondria, chloroplasts).
- Diploid
versus haploid cells.
Genetics
- Haploid
versus diploid (and polyploid) organisms
- Alleles
- Recombination
(crossing over)
