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?

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

One problem might of been that it was to hard to see because it was small.
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.
I think it would the lower grade of technology that would be a roadblock.
maybe not having the tools needed to figure it out.
not having enough money

Havibg the correct technolegy to see it.

They did not have a lot of stuff to learn more about DNA
Didn't have the laser to cut the cell
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.
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.
The scientist did not have the technology to look for the DNA and stuffs.
They did not have a lot of good equipment and some other theories were popular.

They would probably have to kill stuff to find DNA.

This took so long to understand because back then the scientist didn't have the same modern technology to help them learn and
It would be hard for them to learn about DNA because they didn't have all the technology that we have today.
Don't have the money or the right kind of machinery and equipment.

They dident have the right technology back then.
Knowing how to properly handle and/or extract a DNA.
One of the problems might have been not enough money to get recources.
Some problems would be the cost of the research. A roadblock would be getting legal confirmation to do the research.
A roadblock to a scientific break through could be death.
A roadblock might be that there is millions of different "codes" of D.N.A.
Primitive Technology.
DEATH
A road block could be the technology they have
One of the problems is that they might not have enough money to find the resources and to develop the technology.
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.
A roadblock that can stop you from discovering a scientific breakthrough is lack of money and you can not fund your research
They might not of had the right technology.
One of the problems was probably no have the technology they needed.
They did not have the technology or recourses.

Not enough money,technology and interest.
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.
THe road block might of been getting the dna.
They might not have the correct technology to do so. They might have not been able to get DNA out of a cell.
The didn't have the best technology and not enough money.
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.
