Kathleen Collins (scientist)

Kathleen Collins (scientist) is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kathleen Collins (scientist) rather than just read about it. In short: Kathleen Collins is an American RNA biologist and professor at the University of California, Berkeley. Her research considers telomerase RNA structure and telomere function, and eukaryotic transposable elements.

Key takeaways

Kathleen Collins (scientist) belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kathleen Collins (scientist) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kathleen Collins (scientist) from memory before moving on to harder problems.

Reference excerpt

Kathleen Collins is an American RNA biologist and professor at the University of California, Berkeley. Her research considers telomerase RNA structure and telomere function, and eukaryotic transposable elements. In 2020 she was elected a Fellow of the American Academy of Arts and Sciences.

Early life and education Collins was a graduate student at the Whitehead Institute.

Research and career Collins joined the faculty at the University of California, Berkeley in 1995. Her research has considered the structure and function of the enzyme telomerase. Telomerase is a reverse transcriptase that protects chromosomes by replacing the telomere, a short section of DNA lost from the ends of chromosomes during DNA replication. It was first detected in the late 1970s by Elizabeth Blackburn. The telomere prevents the chromosomes from fusing. Most cells turn off telomerase, restricting their proliferation, whilst cancer cells activate telomerase and encourage cell division. In 2018 Collins reported the most detailed image of the three-dimensional molecular structure of telomerase, which offered hope for the design of drugs that can prevent cancer and ageing. Collins developed a scalpel-free approach to tumour biopsies. Cancer cells shed DNA into blood, DNA that can reveal mutations within the tumours that might make them resistant to treatment. The Collins approach samples small sections of DNA or RNA found in the blood, which can provide information about the presence of a tumour. This type of sampling can also tell whether or not a cancer has metastasised or whether it will respond to certain therapies. In 2017 she decided to spin this technology out into a company; KarnaTeq. In 2020 Collins was elected into the American Academy of Arts and Sciences.

Worked examples

Example 1 — a first encounter with Kathleen Collins (scientist)

Start with the simplest possible case. Write down what Kathleen Collins (scientist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kathleen Collins (scientist) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kathleen Collins (scientist) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kathleen Collins (scientist)

In research: Kathleen Collins (scientist) appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kathleen Collins (scientist) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kathleen Collins (scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American physicists, 21st-century American women physicists, American biophysicists, so understanding it makes those chapters shorter.
In everyday life: Look for Kathleen Collins (scientist) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
