Align Two Sequences : Bioinfomatics - Biology Assignment

Internal Code - MAS1636

Biology Assignment

1) How many ways can you align two sequences, each containing two resides, Seq1:AB and Seq2:CD ? (ABC & D are residues found in Seq 1 and Seq 2). 1-a) First when  no insertion/deletion are allowed 1-b) Second, when you are allowed to have insertions/deletions. Write down the number of possible way to align two sequences and then indicate all possible alignments. 2) Please discuss how many ways you can align two sequences, each containing 3 residues, Seq1:ABC and Seq2:XYZ. 2-a) Start with no  insertion/deletion anywhere, 2-b) Then insertion/deletion is allowed  at the beginning and at the end of the sequence but not in the middle. 2-c) Then insertion//deletion is allowed at any position including in the middle. Write down the number of possible way to align two sequences and then indicate all possible alignments.
