The most ancient mode of energy generating metabolic reaction is Reduction of Nitrate Reduction of Sulfate Oxidation of Nitrate PhotosynthesisThe electron acceptor in the anaerobic conditions in prokaryotes is: Glucose, fructose, maltose SO4^-2 Antioxidants such as Vitamin K Fatty acidsPolytene chromosome is formed due to: Due to extensive transcription process Failure of DNA replication Repeated DNA replication without segregation chromosomes Pairing of homologous chromosomesA bacterial operon contains three structural genes A, B and C in the same order. If polar mutation occurs in gene B, then the effect in protein would be observed in: Only in B In all proteins A, B, and C Complete loss of all proteins Only in B and Cc-Value measures Aneuploid genome content Haploid content of the genome Diploid genome content Polyploid genome contentCarrying capacity of a forest is 20 tones which increases 10 % of its biomass annually. For sustainable forestry how much trees can be harvested for timber so that it has minimum effect on forest and can be harvested annually: 0.5 tone 20 tones 10 tones 1 toneThe biggest disadvantage of sexual reproduction against the asexual reproduction is: Lot of energy and time is consumed in locating mate After fertilization in many cases the zygote fails to develop Only half of the genetic material is passed to offspring from each parent At least two individuals are required for sexual reproductionIn prokaryotes there is single multifunctional fatty acyl synthase sufficient for complete fatty acid synthesis whereas in eukaryotes there are many different enzymes involved in the fatty acid synthesis. The probable explanation for this difference is: Fatty acid synthesis is more stringent in eukaryotes Fatty acids of eukaryotes are different from the prokaryotes Synthesis of fatty acid is by different mechanism in eukaryotes as compare to prokaryotes For better regulation of fatty acid synthesis in eukaryotesVitamin B complex is an essential vitamin for humans because: It is obtained only from animal sources It is obtained only from plant sources It act as the cofactor for various metabolic enzymes It is directly utilized in various metabolic reactionsAmong the following which statement is NOT correct for X-linked recessive disorder? Males always passes trait to all of his sons Females are diseased only when their mother is carrier and father is diseased Females with such disorders are unknown Males carrying the diseased allele are always diseasedAmong the following, which is a sex-linked disorder: Myxoderma Color blindness Cretinism Night blindnessWhich of the following statement is NOT correct regarding the genetic code? Third base of anticodon in not necessary for specificity One Amino acid can have more than one codon In eukaryotes the start codon is AUG Genetic code is not strictly universalIn the test cross, the F1 progeny is crossed with: Either of the parents Dominant parent Heterozygous parent Recessive parentIn submerged roots of mangrove plants the recycling of NAD⁺ is carried out by: Glycolysis Cellular oxidation Fermentative metabolism Electron transport chainChemolithotrophs obtain their carbon from CO2 and energy from: Organic compounds Inorganic compounds Water SunlightYou have reached at the End of this Mock Test.
