Question
65) Mendel's observation of the segregation of alleles in gamete formation has its basis in which of the 65) following phases of cell division? A) prophase I of meiosis C) anaphase of mitosis B) metaphase II of meiosis D) anaphase I of melosis 66) Which of the following characteristics, structures, or processes is common to bacteria and viruses? 66) A) cell division B) ribosomes C) genetic material composed of nucleic acid 67) Semiconservative replication involves a template. What is the template? 67) A) single-stranded binding proteins C) an RNA molecule B) DNA polymerase D) one strand of the DNA molecule 68) What provides the energy for the polymerization reactions in DNA synthesis? 68) A) DNA polymerase B) the deoxyribonucleotide triphosphate substrates C) breaking the hydrogen bonds between complementary DNA strands GA66 69) Identify the lagsing strand durinulication of DAaring from a double helx in the figure6)_ above. A) b 70) The leading and the lagging strands differ in that A) the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction B) the leading strand is synthesized at twice the rate of the lagging strand C) the leading strand is synthesized by adding nucleotides to the 3' end of the growing strand and the lagging strand is synthesized by adding nucleotides to the 5' end 71) In the process of transcription, 71) A) RNA is synthesized B) mRNA attaches to ribosomes C) DNA is replicated 72) The statement "DNA -RNA -Proteins" A) describes a series of catalytic reactions B) is known as central dogma C) depicts the regulation of gene expressionExplanation / Answer
65) Anaphase I of meosis
Law of segregration occurs during anaphase I of meosis
66) Genetic material composed of nucleic acid
bacteria divide by cell division but not viruses. ribosomes are present in bacteria but not in bacteria
67) one strand of the DNA molecule
semi conservative mode of replication requires DNA as a template for replication
68) the deoxyribonucleotide triphosphate substrates
cleaving of phosphate groups of dNTP's during polymerisation releases energy.
69) C
70) A
71) RNA is synthesised
72) is known as central dogma
