Why was the discovery of DNA in 1953 so important?
It began the search for gene therapy to cure inherited diseases
. … Cures for AIDS, cancer, and heart diseases; our technology is still developing, we could save many lives.
Why was the discovery of the structure of DNA so important?
Understanding the structure and function of DNA has helped
revolutionise the investigation of disease pathways
, assess an individual’s genetic susceptibility to specific diseases, diagnose genetic disorders, and formulate new drugs. It is also critical to the identification of pathogens.
What helped medicine progress faster in the 20th century than in all previous year?
The rapid progress of medicine in this era was reinforced by
enormous improvements in communication between scientists throughout the world
. Through publications, conferences, and—later—computers and electronic media, they freely exchanged ideas and reported on their endeavours.
How the discovery of DNA changed the world?
The discovery of DNA has radically changed the way
we breed and utilise crops
and the means by which we recognise and protect our plant biodiversity. It has accelerated our ability to breed crops with desirable traits such as disease resistance, cold and drought tolerance.
Why is the double helix important?
The double-helix shape
allows for DNA replication and protein synthesis to occur
. In these processes, the twisted DNA unwinds and opens to allow a copy of the DNA to be made. In DNA replication, the double helix unwinds and each separated strand is used to synthesize a new strand.
Is DNA a useful discovery?
The human hereditary material known as deoxyribonucleic acid, or DNA, is a long molecule containing the information organisms need to both develop and reproduce. … Although the discovery of DNA occurred in
1869
by Swiss-born biochemist Fredrich Miescher, it took more than 80 years for its importance to be fully realized.
What does DNA stand for *?
Answer:
Deoxyribonucleic acid
– a large molecule of nucleic acid found in the nuclei, usually in the chromosomes, of living cells. DNA controls such functions as the production of protein molecules in the cell, and carries the template for reproduction of all the inherited characteristics of its particular species.

What did Louis Pasteur discover what procedure did he develop that we use today?
What did Louis Pasteur discover? What procedure did he develop that we still use today? He discovered that microorganisms were to blame for wines going sour. He developed a procedure that involved the process of heating and sealing to destroy the dangerous microorganisms, which became known as
pasteurization
.
What 20th century discovery in medicine do you think was the most important?
The determination of DNA
is widely regarded as the most important discovery of the 20th century in medicine and science. For this work, Crick and Watson were awarded the 1962 Nobel Prize in physiology or medicine, sharing it with Maurice Wilkins (1916-).
How does DNA affect us?
An organism’s DNA
affects how it looks, how it behaves, and its physiology
. So a change in an organism’s DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.
Is genetic mutation good or bad?
A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations with small effects.
Mutational effects can be beneficial, harmful, or neutral
, depending on their context or location. Most non-neutral mutations are deleterious.
What is importance of DNA?
DNA is
pivotal to our growth, reproduction, and health
. It contains the instructions necessary for your cells to produce proteins that affect many different processes and functions in your body. Because DNA is so important, damage or mutations can sometimes contribute to the development of disease.
What causes DNA to form a double helix?
Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held
together by hydrogen bonds between G-C and A-T base pairs
. Duplication of the genetic information occurs by the use of one DNA strand as a template for formation of a complementary strand.
Why is it called a double helix?
The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes
from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder
.
What stabilizes the DNA double helix?
The structure of the DNA helix is stabilized by
van der Waals forces
, hydrogen bonds between complementary organic bases (a base pair), and hydrophobic interactions between the nitrogenous bases and the surrounding sheath of water.
