Which is the simplest form of matter?
elementAn element is the simplest form of matter that has a unique set of properties..
What is the simplest form of water?
Water is a simple molecule — two hydrogens attached to one oxygen. The three atoms normally form a V-shape.
Is virus the simplest living organism?
Because they were clearly biological themselves and could be spread from one victim to another with obvious biological effects, viruses were then thought to be the simplest of all living, gene-bearing life-forms. … By that description, a virus seems more like a chemistry set than an organism.
What is the smallest genome?
Researchers now say that a symbiotic bacterium called Carsonella ruddii, which lives off sap-feeding insects, has taken the record for smallest genome with just 159,662 ‘letters’ (or base pairs) of DNA and 182 protein-coding genes.
What is the simplest living multicellular organism?
It is widely accepted that multicellular organisms such as humans evolved from single-celled life forms. … This alga is the simplest multicellular organism in the eukaryotes and represents a living fossil of the earliest multicellular species in the 200 million years’ evolution of the colonial Volvocales.
What is the simplest form of DNA?
Some scientists hypothesize that nanobes are the smallest form of life, 1/10 the size of the smallest known bacteria….ClaimsIt is a living organism (contains DNA or some analogue, and reproduces).Has a morphology similar to Actinomycetes and fungi.More items…
What is the pure form of matter?
An element is the simplest form of matter which cannot be split into two or more simpler substances by ordinary chemical methods because an element is formed of only one type of atom.
Is a virus a creature?
16, 2019 — Viruses are non-living creatures, consisting of genetic material encased in a protein coat. Once the virus infects a living organism, it can replicate itself and continue on.
Do viruses have DNA?
Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins.
What is the smallest living organism that exists?
Mycoplasma genitaliumMycoplasma genitalium, a parasitic bacterium which lives in the primate bladder, waste disposal organs, genital, and respiratory tracts, is thought to be the smallest known organism capable of independent growth and reproduction. With a size of approximately 200 to 300 nm, M.
What is the simplest living thing?
But if we look for the simplest creatures on the planet, we will find a wee bacterium that lives happily in the digestive tracts of cows and goats: Mycoplasma mycoides. It builds itself from a very modest blueprint—only 525 genes. It’s one of the simplest life-forms we’ve ever seen.
What are the simplest cells?
All living things can be divided into three basic domains: Bacteria, Archaea and Eukarya. The primarily single-celled organisms found in the Bacteria and Archaea domains are known as prokaryotes. These organisms are made of prokaryotic cells — the smallest, simplest and most ancient cells.
What is the largest human gene?
human dystrophin geneThe largest known gene is the human dystrophin gene, which has 79 exons spanning at least 2,300 kilobases (kb).
What is the shortest human gene?

How do most elements exist?
But many of the elements in the periodic table are instead made in the intense environment of an exploding star or “supernova”. The enormous energies released can produce new kinds of fusion as atoms crash into one another, producing elements as heavy as uranium, with its 92 protons.
What is Prokarya?
also pro·car·y·ote (prō-kăr′ē-ōt′) Any of various microorganisms of the domains Archaea and Bacteria, characterized by the absence of a distinct membrane-bound nucleus and membrane-bound organelles and by the simultaneous occurrence of DNA transcription and protein synthesis at the same site, in contrast to eukaryotes.
How do viruses die?
Strictly speaking, viruses can’t die, for the simple reason that they aren’t alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can’t thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.
