| # Biological Sequence Search - concepts and topics
| |
| ## What is the difference between a sequence search and keyword search?
| |
| ## What is the search query in a sequence search?
| |
| ## In the sequence search, what is the search query searched against?
| |
| ## Typically what is the size of a sequence search query? Give examples e.g. a sequence from a single run in an automated DNA sequencer, small insert library sequence, a sequence melded from various contigs in a BAC, etc.
| |
| ## Typically what is the size of a database of sequences? Give examples of different databases commonly used in sequence searches.
| |
| # Sequence Comparison in sequence searching
| |
| ## Parameters used in sequence comparison. Explain the following:
| |
| ### gap penalty
| |
| ### gap extension penalty
| |
| ### k-tuple. What other synonyms are also used?
| |
| ### How are they used in sequence searches?
| |
| ## Substitution Matrices in sequence comparison and sequence search
| |
| ### Explain how substitution matrices bring biological significance into sequence alignments. In other words, why do we use substitution matrices?
| |
| ### How are substitution matrices commonly used in sequence searches constructed?
| |
| ### Give examples of such substitution matrices and their method of construction?
| |
| ### What other substitution matrices can you find besides PAM and BLOSUM
| |
| ### When constructing substitution matrices, we should avoid gaps in alignments. Why?
| |
| ## In a sequence search, what governs our choice of substitution matrices?
| |
| ## If we guess that homologs are more divergent, which substitution matrix should we choose? If we guess that homologs are less divergent, which substitution matrix should we use? Tabulate your recommendations as a guide to your choice whenever you are using sequence searches or comparisons.
| |
| # Heuristic methods
| |
| ## What is the key constraint with exact dynamic programming methods in sequence searches?
| |
| ## Explain, why so many bioinformatics programs, particularly sequence search techniques, use heuristic methods to speed up the computation and how they reduce the search space.
| |
| ## What are the main differences between heuristic BLAST technique and the exact Dynamic Programming algorithm? Explain the main points that makes BLAST a heuristic technique.
| |
| # BLAST and BLAST Flavours
| |
| ## List all the different BLAST programs. Tabulate the type of query, the queried database, the type of sequence compared (nucleotide or amino acid sequence), the technique use and its difference. At a glance, one should be able to see, for example, what is the query sequence (nt or aa seq) used against what kind of database (nt or aa seq db) using what kind of comparison (aa vs aa or nt vs nt).
| |
| ## If you use tblastx to search a database, all the sequences in the database are translated into six frames. This is done for each of your search sequences. How long does it typically take, if you are using NCBI BLAST server or our National BLAST server or our NUS BLAST Server. If you have 100,000 sequences to search, can you think of any refinement to the procedure?
| |
| # The BLAST output
| |
| ## In the BLAST result output, what are the key aspects of information given?
| |
| ## How are the hits ranked?
| |
| ## Explain the colour scheme of NCBI BLAST alignment visualisation?
| |
| ## What happens if more than one local alignment comes from the same target sequence?
| |
| ## What is the meaning of percentage identity and percentage similarity?
| |
| ## The alignment shown for each blast hit, is it a global or a local alignment of the query sequence against the sequence in the database?
| |
| # Substitution Matrices and BLAST Scores
| |
| ## How are BLAST Scores computed?
| |
| ## How does the choice of Substitution matrix affect the score?
| |
| ## What is the significance of the scores
| |
| ## How can differences in scoring system result in different alignments?
| |
| # Statistical Significance and E values
| |
| ## How does one assess the statistical significance of a typical BLAST Search?
| |
| ## Is the E-value in BLAST a probability, strictly speaking? Hint: You can find an answer at the NCBI website.
| |
| ## How does the E-value help you in assessing the BLAST hits?
| |
| # Making Sound Biological inferences from BLAST
| |
| ## If you want to find homologs to your query sequence, what are the most important items to observe in BLAST results?
| |
| ## Before you make an inference that a BLAST hit is a homolog of your query sequence what sort of criteria should be fulfilled typically?
| |
| ## In a BLAST hit alignment, before you can infer that the sub-region in your query sequence that matches another sub-region of a database sequence entry are homologs, what sort of criteria needs to be fulfilled?
| |
| ## How does low complexity regions in a query sequence affect the BLAST Search, and how can we avoid this problem?
