Why align sequences? Sequence alignments can reveal many things about the functional, structural or evolutionary significance of regions of DNA, RNA or protein. Examples: • The degree of similarity between regions of amino acids can tell us how well that region is conserved, which can provide clues about the structural or functional significance of that region. • The DNA sequence alignment of m...

of Lectures 15 & 16: Library: A genomic library is a population of host bacteria, each of which carries a DNA molecule that was inserted into a cloning vector, such that the collection of cloned DNA molecules represents the entire genome of the source organism. The DNA molecules of an organism of interest are isolated, partially digested by an endonuclease restriction enzyme and ligated into ve...

What is linkage disequilibrium? The opposite of linkage equilibrium! Recall Mendel’s 2nd Law: Allels of different genes are passed on independently. When this law holds, there is no correlation between polymorphisms. In this state of random assortment, they are said to be in linkage equilibrium. However, if there are correlated, then they are in linkage disequilibrium. This is the non-random as...
