Bioinformatics Sequence Assembly Gene Identification 1 GK Quiz. Question and Answers related to Bioinformatics Sequence Assembly Gene Identification 1. MCQ (Multiple Choice Questions with answers about Bioinformatics Sequence Assembly Gene Identification 1
Gene identification in prokaryotic organisms is simplified by their lacking _________
Options
A : exons
B : introns
C : coding segments
D : useful nucleotide sequences
Screening the predicted protein sequences against ______ library confirms the prediction and expression of the gene.
Options
A : expressed sequence tag (EST)
B : tags
C : palindromes
D : proteomes
In case of genome sequence assembly which of the given statement is incorrect?
Options
A : Full chromosomal sequences are assembled from the overlaps in a highly redundant set of fragments by an automatic computational method or from the fragment order on a physical map
B : Chromosome cloning is carried out in bacterial artifical chromosomes (BACs)
C : Chromosomes of a target organism are purified, fragmented, and subcloned in fragments of size hundreds of bp
D : Genome sequences are assembled from DNA sequence fragments of approximate length 500 bp obtained using DNA sequencing machines
Which of the given statement is incorrect about Functional Genomics?
Options
A : Functional genomics involves the preparation of mutant or transgenic organisms with a mutant form of a particular gene usually designed to prevent expression of the gene
B : An abnormal properties of the mutant organism does not reveal the gene function
C : When two or more members of a gene family are found, rather than a single match to a known gene, the biological activity of these members may be analyzed by functional genomics to look for diversification of function in the family
D : A more detailed analysis of the relative amount of sequence variability in a chromosomal region within populations of closely related species can reveal the presence of genes that are under selection
Which of the given statement is incorrect about the gene map?
Options
A : Gene order in two related organisms reflects the order that was present in a common ancestor genome. Chromosomal breaks followed by reassembly of fragments in a different order can produce new gene maps
B : Gene order is only revealed by the physical order of genes on the chromosome
C : Sequence variations (polymorphisms) that are close to (tightly linked) a trait may be used to trace the trait by virtue of the fact that the polymorphism and the trait are seldom separated from one generation to the next
D : These types of evolutionary changes in genomes have been modeled by computational methods
Each genome sequence is scanned for protein-encoding genes using gene models trained on known gene sequences from the same organism.
Options
A : True
B : False
C :
D :
Sequencing of genomes depends on the assembly of a large number of DNA reads into a linear, contiguous DNA sequence.
Options
A : True
B : False
C :
D :
TEs (Transposable Elements) can at most comprise one-fourth of the genome sequence.
Options
A : True
B : False
C :
D :
Which of the following information is not directly obtained by microarray analysis?
Options
A : Which genes are expressed at a particular stage of the cell cycle
B : Which genes are expressed at a particular stage of developmental cycle of an organism
C : Which genes are depleted at what time
D : Genes that respond to a given environmental signal to the same extent
