Understanding the Needleman-Wunsch Algorithm

What are the two main types of sequences discussed in bioinformatics?

• Protein and lipid sequences

• Nucleotide and amino acid sequences

• Nucleotide and carbohydrate sequences

• Carbohydrate and lipid sequences

What is the primary purpose of global sequence alignment?

• To identify conserved sequences by introducing gaps

• To exclude all similar regions

• To find the longest sequence

• To identify the shortest sequence

Which type of alignment is used to identify distant homology?

• Partial alignment

• Complete alignment

• Global alignment

• Local alignment

What is the first step in the Needleman-Wunsch algorithm?

• Gap introduction

• Traceback

• Matrix filling

• Initialization

How does dynamic programming help in solving alignment problems?

• By solving the problem in one step

• By increasing the complexity of the problem

• By breaking down a large problem into smaller, manageable sub-problems

• By ignoring the problem
