Genetic transformation occurs when the host DNA takes on foreign DNA and expresses that gene.
In the lab they introduced an ampicillin resistant gene into a bacteria. The bacteria incorporated the gene thus making the bacteria ampicillin resistant.
Escherichia coli colony is made of millions of cells.
Membrane with phospholipid bilayer
Plasmid- circular pieces of DNA that exist outside the main bacterial chromosome and carry their own genes for specialized functions
Gene-piece of DNA that codes for a specific trait
Restriction enzyme- genetic scissors-cut DNA at specific sites-several
Ligase- genetic glue-only one
Genome- entire genetic code for an organism
Taxonomy-classification of all living things 3 Domains
All chromosomes except the sex chromosomes are in the homologous pairs.
Chromosomes are labeled by the centromere.
22 of 23 chromosomes are autosomes.
Transcription occurs in G of mitosis.
Karyotype: visualization of chromosome
DNA Replication: Review DNA ThinkQuest
Replication occurs in S Phase of mitosis.
Lagging strands create fragments known as Okazaki Fragments
Start codon is usually methionine (AUG)
20 amino acids, 4 bases for each codon, 64 codons
UGA, UAA, and UAG are stop codons
