Discovering DNA

The Discovery of DNA took many years what do you think some of the problems may have been in learning about DNA. What would be a roadblock to the scientific breakthrough?

  1. they might have wondered why was blood only in things with a heartbeat

  2. I think that some of the problems that had to do with DNA were not having microscopes to look closely at cells and just the technology in general back then.

    1. This kind of has to do with my previous comment but, I know that they were definately blocked by technology because it wasn't as great as it was today.

  3. One problem might of been that it was to hard to see because it was small.

  4. Having trouble magnifying the cell

    why is DNA only in people? they would have to take blood samples from someone, and they didn't have the tools to do it.

  6. I think it would the lower grade of technology that would be a roadblock.

  7. maybe not having the tools needed to figure it out.

    ReplyDelete
  8. not having enough money

    ReplyDelete
  9. Taking all the blood samples and people not wanting to help and going against the system that they do that. Not having the right materials and technology.

  11. Havibg the correct technolegy to see it.

  12. The discovery of the structure of DNA was reported 50 years ago this month. But the saga began many years before, says Susan Aldridge

    On 25 April 1953, a paper appeared in Nature that was to transform the life sciences - from biochemistry and agriculture, to medicine and genetics. James Watson and Francis Crick, then at Cambridge UNIVERSITY, reported the discovery of the structure of DNA (deoxyribonucleic acid) - the molecule that genes are made of.

  13. They did not have a lot of stuff to learn more about DNA

    ReplyDelete
  14. Didn't have the laser to cut the cell

  15. They would have had to have microscopes to see DNA. I think they would have had those then though. They didn't have modern technology though, like computers and other stuff.

  17. The scientist did not have the technology to look for the DNA and stuffs.

    ReplyDelete
  18. They did not have a lot of good equipment and some other theories were popular.

  19. Something that might block the proccess of learning about DNA is the financial issue.It costs a lot of money for tests and machines so its hard to afford them.

    ReplyDelete
  20. They would probably have to kill stuff to find DNA.

    ReplyDelete
  21. A couple road blocks would be that to see the DNA you would need a microscope and they probably didn't have a good enough one or even didn't have one at all, And the may have had trouble getting the cell with the limited technology they had then.

  22. it really comes down to technology and being able to "connect the dots." DNA was first isolated in 1869. In those days, people were developing lab techniques they could use to grind up biological samples and purify different kinds of molecules. In parallel, others were studying inheritance. As the ideas spread through the world (don't forget, we didn't have the Internet in those days), some people realized that DNA was the genetic material. That happened in 1944. So it only took 9 years from that discovery to apply the technique called X-ray crystallography to learn the structure of DNA. So the answer is that we need the technology to be available, the ideas to develop and spread, and the right people to get motivated to connect the dots.

  23. This took so long to understand because back then the scientist didn't have the same modern technology to help them learn and

    ReplyDelete
  24. It would be hard for them to learn about DNA because they didn't have all the technology that we have today.

    ReplyDelete
  25. Don't have the money or the right kind of machinery and equipment.

    ReplyDelete
  26. They did NOT know how to properly handle the DNA and probably break it or how to extract it from the cell or even they did not have the right technology to examine it.

  27. They dident have the right technology back then.

  28. Knowing how to properly handle and/or extract a DNA.

  29. One of the problems might have been not enough money to get recources.

    ReplyDelete
  30. Some problems would be the cost of the research. A roadblock would be getting legal confirmation to do the research.

    ReplyDelete
  31. A roadblock to a scientific break through could be death.

    ReplyDelete
  32. A roadblock might be that there is millions of different "codes" of D.N.A.

    ReplyDelete
  33. Primitive Technology.

    ReplyDelete
  34. A road block could be the technology they have

    ReplyDelete
  35. One of the problems is that they might not have enough money to find the resources and to develop the technology.

    ReplyDelete
  36. It must have been very hard to learn about DNA because first they didn't have the high def microscopes so they couldn't look at it as easy.

    ReplyDelete
  37. A roadblock that can stop you from discovering a scientific breakthrough is lack of money and you can not fund your research

    ReplyDelete
  38. They might not of had the right technology.

    ReplyDelete
  39. One of the problems was probably no have the technology they needed.

    ReplyDelete
  40. They did not have the technology or recourses.

    Not enough money,technology and interest.

    ReplyDelete
  50. Since DNA is very small, it was almost impossible with say... the 1800's technology, if they even had any. You need very expensive equipment, and lots of knowledge to research DNA.

    ReplyDelete
  51. THe road block might of been getting the dna.

    ReplyDelete
  52. They might not have the correct technology to do so. They might have not been able to get DNA out of a cell.

    ReplyDelete
  53. The didn't have the best technology and not enough money.

    ReplyDelete
  54. DNA can sometimes be extremely small and hard to see through a microscope, meaning you would have to buy more expensive equipments, such as micro scopes, to discover certain types of cells and DNA.

    ReplyDelete
  55. They don't have money or equipment.
