When was DNA discovered?

As with the discovery of inheritance and evolution, the story of the discovery of the structure DNA is well known; starting with the Rosalind Franklin’s first image of the double helix in 1952 and then subsequently James Watson’s and Francis Crick’s model of the double helix structure in 1953. However, Oswald Avery had already identified DNA in 1944 as the primary point for hereditary information. But the structure of DNA cannot be overlooked for its relevance in our understanding of so much of what is now considered common knowledge in biological sciences.

What did Alexander Fleming discover?

Alexander Fleming wasn’t setting out in 1928 to revolutionize biological science when he discovered that something in Penicillium mold spores was able to kill staphylococcal bacteria in a petri dish. As is often the case in science, discoveries make remarkable impacts on research that are totally unrelated to the field they were created to help. Fleming was just trying to find a way to prevent anaerobic infections from being so deadly, not looking to find the world’s first antibiotic. But along the way, the discovery of antibiotics have been utilized in innumerable research, as selection tools in transformation and cell culture, as well as a host of other fields and studies.

What did Arthur Kornberg discover?

In 1956, Arthur Kornberg and his lab forever changed the world of molecular biology with the discovery of DNA polymerase from E. coli cells. In one instant, scientists were now finally capable of synthesizing new DNA sequences onto an existing DNA strand. The use of the original DNA Polymerase and subsequent polymerases discovered by Arthur’s son, Thomas Kornberg, and others have created the bedrock of molecular biology in regards to PCR, cloning, transformation and sequencing. Without these workhorses of the lab, much of what we currently understand about our DNA and life would be nonexistent.

When did gel electrophoresis start?

But it wasn’t until the 1940s that scientists started using gel matrices to separate compounds into discrete bands. And it wasn’t until the 1960s that gel electrophoresis would really be used to start identifying DNA and other biological molecules that would give birth to the field of molecular biology.

What did Darwin's finches and peas do?

But their long reaching conclusions helped to spur the explosion of growth in the area of biology for the last 170 years. And while it would take the discovery of DNA in the 1950s to sow the seeds of genetic evolutionary studies, we all owe a debt to these naturalist founders who laid the groundwork for many of the things we now take for granted while conducting our research.

When were restriction enzymes first used?

The first restriction enzymes were discovered in the early 1950s by Salvadore Luria, Jean Weigle and Giuseppe Bertani. But the enzymes they found were all type I enzymes that cleaved DNA randomly from a recognition site. In 1970, Hamilton Smith and associates discovered the more popular type II restriction enzymes that cleave at their site of recognition, and Daniel Nathans showed that by cleaving in those places, they could separate the fragments via gel electrophoresis in order to map the DNA. The use of restriction enzymes to produce a predictable cleaving pattern to work from has become a benchmark in cloning and mapping.

What were Henrietta Lacks' cells?

The cervical cancer cells that were taken from Henrietta Lacks before she died in 1951 have become a benchmark in the history of cancer research and knowledge. The immortal HeLa cells made medical research easier, more robust and repeatable. The cell line is what allowed for the creation of Salk’s first polio vaccine in 1952. Since its discovery, there have been over 11,000 patents created involving the HeLa cells. It is safe to say that without Henrietta’s cells, a great body of research would have been slower and biomedical advancements a great deal more ponderous.

What was Aristotle's first scientific discovery?

Ancient Greek philosopher Aristotle isn't often considered when it comes to great biological discoveries, but his work on the classification of living things was revolutionary. Referred to as the 'Ladder of Life', Aristotle's classification system was used up until the 19th century. He was the first person to recognise the relationships between species, and organise accordingly.

What did Charles Darwin do?

Charles Darwin (1809–1882): theory of evolution. Probably the most famous naturalist of all time, Charles Darwin's contribution to biology and society is immense. He established that all species of life descended over time from common ancestors, with species continuing to exist through the process of natural selection.

Why did Darwin use peas?

He used peas to discover and demonstrate the laws of genetic inheritance, coining the terms ‘dominant’ and ‘recessive’ genes in the process . The laws were rediscovered at the turn of the 20th century and provided the mechanism for Darwin's theory of natural selection to occur.

Who is the most famous scientist for his contribution to microscopy?

Antonie van Leeuwenhoek (1632–1723): microbiology. Antonie van Leeuwenhoek is well known for his contributions to microscopy and how he applied this to the field of biology. He revolutionised a technique for creating powerful lenses, which some speculate were able to magnify up to 500 times.

Who came up with the system of naming, ranking and classifying organisms we still use today?

Carl Linnaeus (1707–1775): modern taxonomy. A botanist, physician and zoologist, Carl Linnaeus came up with the system of naming, ranking and classifying organisms we still use today. It was his vast collection of specimens of plants, animals and shells that led him to think up a way of grouping and naming species.
