Lecture 1 Flashcards
Molecular Genetics
How gene sequence works
Transmission Genetics
Parent to offspring (inheritance)
Population Genetics
Allele distribution in a group of individuals
Forward genetics
Find a mutant in the wild, map gene, ID what gene does
Reverse genetics
Take any wildlife gene, create mutation, assess phenotypic changes
Model organisms include;
E.Coli, yeast, fruit flies, C.elegans, Zebrafish, Mice
What is the Central Dogma in Biology?
Nucleic acids contain sequence information which codes for functional products.
What does ΔF508 stand for?
Δ-deletion, F-phenylalanine, 508- 508th AA
What is a gene?
An organization of sequences which fall into two categories; Regulatory and Coding.
What is a protein?
Functional product of a gene
What is the nature of a gene?
Sequence info with specific components
What is the nature of a trait?
Carried out by a protein
How does DNA store info?
In the form of base pairs as a double helix
What is a chromosome?
A very long double helix. Bigger gene = more codons
Define locus
Each gene has a specific position on a chromosome
