Which of the following statement is NOT correct regarding the genetic code? Genetic code is not strictly universal In eukaryotes the start codon is AUG Third base of anticodon in not necessary for specificity One Amino acid can have more than one codonIn submerged roots of mangrove plants the recycling of NAD⁺ is carried out by: Cellular oxidation Electron transport chain Fermentative metabolism GlycolysisPolytene chromosome is formed due to: Repeated DNA replication without segregation chromosomes Failure of DNA replication Pairing of homologous chromosomes Due to extensive transcription processAmong the following, which is a sex-linked disorder: Night blindness Color blindness Myxoderma CretinismAmong the following which statement is NOT correct for X-linked recessive disorder? Females with such disorders are unknown Males carrying the diseased allele are always diseased Males always passes trait to all of his sons Females are diseased only when their mother is carrier and father is diseasedChemolithotrophs obtain their carbon from CO2 and energy from: Organic compounds Water Sunlight Inorganic compoundsc-Value measures Aneuploid genome content Haploid content of the genome Polyploid genome content Diploid genome contentVitamin B complex is an essential vitamin for humans because: It is obtained only from plant sources It is directly utilized in various metabolic reactions It act as the cofactor for various metabolic enzymes It is obtained only from animal sourcesThe electron acceptor in the anaerobic conditions in prokaryotes is: Fatty acids Glucose, fructose, maltose Antioxidants such as Vitamin K SO4^-2A 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: Complete loss of all proteins Only in B and C In all proteins A, B, and C Only in BThe biggest disadvantage of sexual reproduction against the asexual reproduction is: After fertilization in many cases the zygote fails to develop At least two individuals are required for sexual reproduction Lot of energy and time is consumed in locating mate Only half of the genetic material is passed to offspring from each parentCarrying 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: 10 tones 20 tones 1 tone 0.5 toneThe most ancient mode of energy generating metabolic reaction is Oxidation of Nitrate Photosynthesis Reduction of Sulfate Reduction of NitrateIn 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: For better regulation of fatty acid synthesis 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 Fatty acid synthesis is more stringent in eukaryotesIn the test cross, the F1 progeny is crossed with: Either of the parents Recessive parent Heterozygous parent Dominant parentYou have reached at the End of this Mock Test.
