1. In bacteria, the transcribed mRNA is immediately functional and can be directly translated.

2. A true-breeding line is one that, having undergone continuous self-pollination, shows the stable trait inheritance and expression for several generations.

3. The genetic code is then read by tRNA, which acts as an adapter molecule.

4. Both the DNA strands are not having the same sequence while reading the same direction.

5. Scientists can examine all the genes in a genome, such as the transcripts in a specific tissue, organ, or tumor, and investigate how thousands of genes and proteins interact within complex networks to coordinate the chemistry of life.

6. Chromosomal aberrations are easily studied through karyotype analysis.

7. Variation is the process by which characters are passed on from parent to progeny; it is not the basis of heredity.

8. Shaded Circle/Square symbol in a pedigree tree, represents an individual who does not express the trait or disorder.

9. A DNA segment that codes for RNA can be referred to, in simplistic terms, as a gene.

10. Anteater is similar to Numbat.

11. Some generic disease can be diagnosed by urine analysis.

12. The Big Bang Theory talks of a many huge explosions unimaginable in physical terms.

13. A pure-line is one that, having undergone continuous cross-pollination, shows the stable trait inheritance and expression for several generations.

14. Mendel’s laws were later extended into the ‘Chromosomal Theory of Inheritance.’ However, it was discovered that Mendel’s Law of Independent Assortment does not apply to genes located on the same chromosome.

15. Once set in, the total DNA of an organism gets duplicated or replicated, whereas in transcription only a segment of DNA and only one of the strands is copied into RNA.

16. The hallmark of DNA’s double-stranded helical structure is not the hydrogen bonding between the bases of opposite strands.

17. Eye of the octopus and of mammals are an example of analogous structures and for divergent evolution.

18. Female honey bee can have father and thus can have sons.

19. Early human (8000 – 1000 B.C.) know about scientific basis of inheritance.

20. Biochemical similarities are pointing to the same shared ancestry as structural similarities among diverse organisms.

21. Mutation, defined as a change in genetic material, can involve a single base pair in DNA (point mutation), such as in sickle-cell anemia, caused by a single base change in the gene coding for the beta chain of haemoglobin.

22. Klinefelter’s syndrome – tall stature with masculine character.

23. Alfred Wallace, a naturalist who worked in Galapagos Archipelago, had also come to conclusions similar to Darwin around the same time.

24. Mendel’s experiments had a smaller sampling size, which gave lesser credibility to the data that he collected.

25. In most cases, the sequences of the operator bind a repressor protein.

26. In a pedigree tree, Arabic Numerals: Used to number individuals within each generation.

27. Linkage maps correspond to the arrangement of genes on a chromosome.

28. DNA replication does not follow a semiconservative model, and complementary hydrogen bonding does not guide the process.

29. Failing to derive meaningful knowledge from DNA sequences will not shape research in the coming decades, leaving our understanding of biological systems stagnant.

30. The universe is vast.

31. Banding pattern, in genetic fingerprinting, do not differ between monozygotic twins.

32. Biochemical similarities are pointing to the different shared ancestry as structural similarities among diverse organisms.

33. The star we see today is an object whose emitted light started its journey millions of years back and from trillions of kilometres away and reaching our eyes now.

34. For the first time statistical analysis and mathematical logic were applied to problems in biology by Darwin.

35. Lemur is similar to Spotted cuscus.

36. Klinefelter’s syndrome – congenital heart disease.

37. Some characters show incomplete, and some show co-dominance.

38. The two RNA molecules if produced simultaneously would be complementary to each other, hence would form a double stranded DNA.

39. Banding pattern, in genetic fingerprinting, do not differ between maternal twins.

40. Statistical analysis and mathematical logic were applied to problems in biology by Hardy and Weinberg.

41. Eye of the octopus and of mammals are an example of homologous structures and for convergent evolution.

42. Similarities in genes performing a given function among diverse organisms give clues to common ancestry.

43. The universe is 20000 billion years old.

44. Mendel used the term ‘alleles,’ now we call them as alleles.

45. Experimenting on opposing traits of an organism expanded on by many scientists to account for all the diverse natural observations and the complexity inherent in them.

46. In phenylketonuria patients, tyrosine is accumulated.

47. One of the applications of polymorphism in repetitive DNA sequences is DNA fingerprinting.

48. The principle of complementarity governs the process of transcription without any exception.

49. During the mid-nineteenth century that headway was made in the understanding of inheritance.

50. In addition to application in forensic science, genetic fingerprinting has much wider application, such as in determining population.
