Mollivirus sibericum

Mollivirus sibericum is a biology 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 Mollivirus sibericum rather than just read about it. In short: Mollivirus sibericum is a giant virus discovered in 2015 by French researchers Chantal Abergel and Jean-Michel Claverie in a 30,000-year-old sample of Siberian permafrost, where the team had previously found the unrelated giant virus Alphapithovirus sibericum. Mollivirus sibericum is a spherical DNA virus with a diameter of 500–600 nanometers (0.5–0.6 μm).

Key takeaways

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

Reference excerpt

Mollivirus sibericum is a giant virus discovered in 2015 by French researchers Chantal Abergel and Jean-Michel Claverie in a 30,000-year-old sample of Siberian permafrost, where the team had previously found the unrelated giant virus Alphapithovirus sibericum. Mollivirus sibericum is a spherical DNA virus with a diameter of 500–600 nanometers (0.5–0.6 μm). Mollivirus sibericum is the fourth ancient virus that scientists have found frozen in permafrost since 2003. It has a sister taxon, Mollivirus kamchatka.

Description Mollivirus sibericum is an approximately spherical virion 0.6 μm in diameter. It encloses a 651 kb GC-rich genome encoding 523 proteins, of which 64% are open reading frames. The host's ribosomal proteins are packaged in the virion.

Worked examples

Example 1 — a first encounter with Mollivirus sibericum

Start with the simplest possible case. Write down what Mollivirus sibericum claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Mollivirus sibericum 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 Mollivirus sibericum 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 Mollivirus sibericum

In research: Mollivirus sibericum appears in biology 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 Mollivirus sibericum 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: Mollivirus sibericum is common in secondary-school and first-year university syllabi. It links to neighbouring topics Nucleocytoplasmic large DNA viruses, Species described in 2015, Unaccepted virus taxa, so understanding it makes those chapters shorter.
In everyday life: Look for Mollivirus sibericum 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.
