C : It uses a linear discriminant function
D : The linear discriminant function is combined with signal and content information
Which of the following is correct regarding the method for prokaryotic operon prediction?
Options
A : It relies on two kinds of information: gene orientation and intergenic distances of a pair of genes of interest and conserved linkage of the genes based on comparative genomic analysis
B : It relies only on the gene orientation and intergenic distances of a pair of genes of interest
C : It relies only on the conserved linkage of the genes based on comparative genomic analysis
D : The prediction cannot be done manually using the rules
Once an operon structure is known ______ for the presence of a promoter and regulatory elements _____ in the operon do not possess such DNA elements.
Options
A : only the first gene is predicted, whereas other genes
B : only the first hundred genes are predicted, whereas next few genes
C : only first two genes are predicted, whereas next few genes

Which of the following is incorrect regarding the Prediction for Eukaryotes?
Options
A : The consensus patterns are only derived from bioinformatics studies
B : The experimentally determined DNA binding sites are compiled into profiles and stored in a database for scanning an unknown sequence to find similar conserved patterns
C : The consensus patterns are derived from experimentally determined DNA binding sites
D : The ab initio method for predicting eukaryotic promoters and regulatory elements relies on searching the input sequences for matching of consensus patterns of known promoters and regulatory elements
Which of the following is incorrect regarding the ab initio approaches?
Options
A : The conventional approach to detecting a promoter or regulatory site is through matching a consensus sequence pattern represented by regular expressions
B : The conventional approach to detecting a promoter or regulatory site is through matching a position-specific scoring matrix constructed from well-characterized binding sites
C : The consensus sequences or the matrices are relatively short, covering 6 to 10 bases
D : The consensus sequences or the matrices are relatively large, covering 700 to 1000 bases
