6. To understand the origin of life, we need to understand the evolution of stars.

7. The mapping of the human genome involved using information on polymorphisms of restriction endonuclease recognition sites and repetitive DNA sequences known as microsatellites.

8. If both strands act as a template, they would code for RNA molecule with different sequences, and in turn, if they code for proteins, the sequence of amino acids in the proteins would be the same.

9. In phenylketonuria patients, phenylalanine is not excreted through urine.

10. Turner’s Syndrome – characteristic palm crease.

11. Similar genes in similar organisms performing dissimilar functions is an example of divergent evolution.

14. The genetic code is not read by tRNA, which does not act as an adapter molecule.

15. Tubers of potato and sweet potato are anatomically similar structures, though they perform similar functions.

16. Some traits are dominant over others, meaning dominant traits are expressed when the factors are in a heterozygous condition (Law of Dominance).

17. The diversity of life forms on Earth has not changed over millions of years.

18. Considering the size of the universe, the solar system is indeed a speck.

19. Tubers of potato and sweet potato are an example of homologous structures and for convergent evolution.

20. The Big Bang Theory talks of a many huge explosions imaginable in physical terms.

21. First human-like being, the hominid, was called Homo habilis.

22. Some characters are dominant over others.

23. Fossils discovered in Java in 1891 revealed Homo erectus lived about 15 mya, had a cranial capacity of 650cc, probably ate meat.

24. The geological history of earth somehow correlates with the biological history of earth.

25. In eukaryotes, however, genes are split, with coding sequences (exons) interrupted by non-coding sequences (introns).

26. Homology is not accounted for by the idea of branching descent.

27. The geological history of earth closely correlates with the biological history of all species.

28. Huge clusters of galaxies comprise the solar system.

29. The common ancestors may present at same periods in the history of earth.

30. Based on dihybrid cross observations, Mendel proposed that something was being unstably passed down, changed, from parent to offspring through the gametes, over successive generations.

31. Homo habilis probably did not eat fruits.

32. Marsupial mole is a marsupial mammal.

33. Eye of the octopus and of mammals are an example of homologous structures and for divergent evolution.

34. Researchers cannot study all the genes in a genome, nor can they examine transcripts in tissues, organs, tumors, or how genes and proteins interact in networks to drive the chemistry of life.

35. Turner’s syndrome – Many “loops” on fingertips.

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

37. Phenylketonuria is inborn error of metabolism is also inherited as the sex linked dominant trait.

38. DNA from a single cell is not enough to perform DNA fingerprinting analysis.

39. Traits are the unit of inheritance.

40. Based on monohybrid cross observations, Mendel proposed that something was being unstably passed down, unchanged, from parent to offspring through the gametes, over one or two generations.

41. Dominant wild type alleles are usually represented with (+) sign in superscript.

42. Klinefelter’s Syndrome karyotype is 45, XO.

43. 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.

44. A challenging task in HGP was assigning the genetic and physical maps on the genome.

45. In case of the character of pod shape, I is used for the inflated trait and i for the ‘constricted,’ and I and i are alleles of each other.

46. Charles Darwin introduced natural selection and implied it as a mechanism of evolution.

47. Inheritable mutations can be studied by generating a pedigree of a family.

48. Female honey bee can have grandfather and thus can have grandsons.

49. All recessive traits expressed in homozygous allelic combination but all homozygous allelic combination won’t express recessive traits.

50. Mendel observed that the expression of traits in offspring follows a definite pattern across generations—first (F1), second (F2), and beyond.
