Predictive Methods Using DNA Sequences -3

What is the accuracy of PROCRUSTES in predicting correct gene structures when using candidate proteins?

• 90%

• 75%

• 50%

• 99%

What is the purpose of GenomeScan program?

• To predict gene structures based on DNA sequence alone

• To assign a higher score to putative exons that overlap BLASTX hits

• To analyze nonstandard gene structures

• To identify protein sequences in the public databases

What is the main function of the Type column in the GENSCAN output table?

• Provides the probability value of the prediction

• Shows the direction of the prediction

• Indicates the length of the prediction

• Specifies the type of prediction (e.g., initial exon, internal exon)

What is the accuracy of GENSCAN exons with a very high probability value (P > 0.99) when matching a true, annotated exon?

• 50%

• 75%

• 88.1%

• 97.7%

What is the purpose of the GenomeScan program when a moderate or closely related protein sequence is available?

• To improve the accuracy of gene structure prediction

• To predict gene structures based on DNA sequence alone

• To assign a lower score to putative exons

• To ignore regions of high detected similarity

What does the algorithm of PROCRUSTES require before making a prediction?

• Public databases

• DNA sequence with content-based signals

• BLASTX hits

• Candidate proteins

What is the significance of the phrase 'he who stretches' in the context of Greek mythology?

• Symbolizes the idea of forcing something to fit

• Represents the accuracy of gene prediction

• Describes the hero Theseus

• Refers to a bandit with a warped idea of hospitality

What is the main advantage of using candidate proteins in the PROCRUSTES algorithm?

• Reduces the need for spliced alignment algorithm

• Increases the number of predicted exons

• Provides information about public databases

• Improves the accuracy of gene structure prediction
