Microbial Genetics
The Study of Genes
Heredity
How Nucleic Acids are transmitted from one to another
Eukaryotes
Have linear complex DNA
Prokaryotes
Single circular chromosome that twists
Nucleotides
-Phosphate group
-sugar : deoxribose, complementary, nitrogen blues / ademome
Genes
Basic unit of heredity
Alleles
Genes found at the same position (Locus)
Mutations
Changes in DNA sequence in genes
DNA / Base sequences
A-T & C-G
3 ways of transfering genetic info:
Replication
Transcription
Translation
Replication (DNA)
-Simpliest -> used by bacteria
-DNA makes copies
Transcription (DNA)
-Takes small sections and duplicates the one are it needs -> it becomes
mRNA - carries info from DNA to ribosomes
Ribosome DNA - Picks up mRNA and reads code so it can begin in assembling of correct amino acids -> Protein building
* where protein synthesis begins
Translation (DNA)
-Has to be made
-Transfer RNA goes to cytoplasm and finds right bases
-Is protein Synthesis
Codon
Messenger RNA carries 3 baes that read as amino acids ( Some have more than 1 codon )
Genetic code
Relationship between amino acids and codons
Start codon
First code in MRNA
Stop Codon
Last Codon
Genotype
DNA code, whats always intended
Phenotype
Specific traits a characteristic produced by genotypes
