Question

5) Genetically modified organisms: A) have acquired genes artificially, B) cause disease and mutations in humans, C) are not important in agriculture; D) are not regulated and therefore unsafe

6) Therapeutic cloning of embryonic stem cells can: A) produce all cell types in the body; B) save human lives; C) be obtained only from embryos; D) all are true

7) Cutting DNA with a specific restriction enzyme produces _____ that can be separated by gel electrophoresis. A) restriction fragments; B) enzymes; C) recombinant DNA; D) plasmids

8) DNA fingerprinting can be used to rule out or eliminate a suspect in a crime but not to identify a perpetrator (criminal). (True/False)

9) The human genome (entire DNA of a human) contains about 25,000 genes and about 50% of that genome is noncoding (introns). (True/False)

10) Currently gene therapy can be said to be: A) far off in the future; B) not possible; C) cheap and easy; D) promising

11) The only area of research that will benefit from the human genome project is the study of human evolution. (True/False)

12) The human genome project is enhancing the understanding of evolutionary history. (True/False) 13) Approximately what percentage of human DNA is noncoding? A) 97%; B) 64%; C) 99.9%; D) 79%

Answer 1

Ans-5.) Genetically modified organisms: A) have acquired genes artificially.

Ans-6.)Therapeutic cloning of embryonic stem cells can: (D) All are true.. can produce all cell types in the body (pluripotent), save human lives, obtained only from embryos.

Ans-7.)Cutting DNA with a specific restriction enzyme produces (A) Restriction fragments that can be separated by gel electrophoresis.

Ans-8.) DNA fingerprinting can be used to rule out or eliminate a suspect in a crime but not to identify a perpetrator (criminal). False

Ans-9.)The human genome (entire DNA of a human) contains about 25,000 genes and about 50% of that genome is noncoding (introns). True

Ans-10.)Currently gene therapy can be said to be:(D) Promising

Ans-11.)The only area of research that will benefit from the human genome project is the study of human evolution. False

Ans-12.)The human genome project is enhancing the understanding of evolutionary history. True

Ans-13.)Approximately what percentage of human DNA is noncoding (A) 97 % , ideally less than 2 % or around 1% of the human genome is directly coding in nature , rest 98% - 99% is non coding but have regulatory roles. (so please verify this question).
