Question

47. There are around 45 different transfer RNS in a typical human cell rue 48. DNA codes for messenger RNAs, while nonsense DNA codes for long non-coding RNAS False 49. Exons are found in archea, bacteria and eukaryotes, although they appear to be rare and not as important 49. Translation occurs in nucleus of eukaryotes and the nucleoid of prokaryotes False in archea and bacteria. 50. Waksman probably coined the term antibiotic, while discovering streptomycin 51 Selman Waxman is known for staining, immunity and the magic bullet rve 52. Metchnikov won a noble prize and coined the term phagocytosis and is considered by some the father of- innate immunity 53. Endospores may have genes for antibiotic resistance and toxicity and are probably a major player in drug resistance 54.One giant Armillaria sp, a mycorhizzae, occupies 1,600 football fields and is probably thousands of years old. Fo Fals SS. Fungi can be saprophytic, parasitic and a few are predaceous 56. Hyphae are filamentous structures that make up the mycelium of most fungi Tu 57. There are about a hundred thousand described species of fungi with the largest number in the Ascomycota 58. Modified adenoviruses filoviridae and retroviruses like HIV are being used as vectors in biotechnology. Tr 59. The envelope of viruses is made of lipids derived from host cell membrane or the endoplasmic reticulum by budding. 60 We are not well prepared for bird flu or any pandemic. False 61. Viral diseases included rabies, measles,small pox, mumps, monkey pox, herpes, warts, ebola Lalse hemorrhagic fever, dengue and shingles 62. Prions are infectious genetic material that were named by Stanley Pruisner and are found in many twe vertebrates, like sheep, minks, cattle, humans, and in some fungi 63. The flaviviridae includes Yellow fever, hepC, West Nile viruses and Dengue r 64. Diatoms have been used in clarifying wine, making dynamite , played a role in the Nobel prize,make oil peas from sunlight and CO2 and some produce domoic acid which can erase short term memory 65. Ebola and Marburg are in the Filoviridae U 66. There is no pressing need for man to produce new vaccines, like DNA vaccines, because viruses represent PafSe a minor threat to the human race, therefore the politicians and leaders of the world are well-informed 67 The lack of medical and biological literacy of our politicians is a huge problem especially in decisions about the health care industry 68. Retrotransposons may have given rise to some viruses Trul 69. Retrotransposons represent a large part of our DNA-60% or more 70, Retroviruses have inserted there RNA into our ancestors so that may be 10% of the nonsense Tree DNA of humans is viral. The II. Multiple Choice 1. The following describes viruses

Explanation / Answer

Solution:-

47.) TRUE

48) false becasue DNA codes for both coding and non coding rna but non coding rna doesn't form any protein.

49) false translation occurs in cytoplasm of eukaryotes as well as prokaryotes

49) false as introns are rare because introns doesn't code for protein and size of dna in archae and bacteria is too small so probability of introns is very rare

50) true.
