Oligo- (prefix): Means just a few or scanty. From the Greek “oligos’, few, scanty. Examples of terms starting with oligo- include oligodactyly (few fingers), oligohydramnios (too little amniotic fluid) and oligospermia (too few sperm).
Similarly, What is oligonucleotide with example?
Oligonucleotides are short DNA or RNA molecules, oligomers, that have a wide range of applications in genetic testing, research, and forensics. … For example, an oligonucleotide of six nucleotides (nt) is a hexamer, while one of 25 nt would usually be called a “25-mer”.
Additionally, What do the prefixes oligo and poly mean? , olig- 1. Combining forms meaning a few, a little; too little, too few. 2. chemistry Used in contrast to “poly-” in describing polymers (e.g., oligosaccharide).
What does Hypo mean as a prefix?
Definition of hypo- (Entry 5 of 5) 1 : under : beneath : down hypoblast hypodermic. 2 : less than normal or normally hypesthesia hypotension. 3 : in a lower state of oxidation : in a low and usually the lowest position in a series of compounds hypochlorous acid hypoxanthine.
What is hypo in medical term?
Hypo = below, less than normal.
What’s the meaning of oligonucleotide?
Medical Definition of oligonucleotide
: a relatively short single-stranded nucleic-acid chain (as an oligodeoxynucleotide or oligoribonucleotide) usually consisting of up to approximately 20 nucleotides.
How are oligonucleotides made?
Oligonucleotide synthesis is the chemical synthesis of relatively short fragments of nucleic acids with defined chemical structure (sequence). … Products are often isolated by high-performance liquid chromatography (HPLC) to obtain the desired oligonucleotides in high purity.
Is mRNA an oligonucleotide?
In contrast, oligonucleotides are macromolecules that target pre-mRNA and mRNA, the carriers of genetic information before it is translated into proteins.
What is the meaning of the prefix poly -?
Poly-: 1: Prefix meaning much or many. For example, polycystic means characterized by many cysts. 2: Short form for polymorphonuclear leukocyte, a type of white blood cell.
What does the prefix mean in medical terms?
Prefixes are located at the beginning of a medical term. The prefix alters the meaning of the medical term. It is important to spell and pronounce prefixes correctly. Many prefixes that you find in medical terms are common to English language prefixes.
What is Uresis?
: excretion of urine : urination.
What means of Hypo?
Hypo-: Prefix meaning low, under, beneath, down, or below normal, as in hypoglycemia (low blood sugar) and hyposensitivity (undersensitivity). The opposite of hypo- is hyper-.

What does the Prefix hypo mean in chemistry?
Scientific definitions for hypo
A prefix that means “beneath“ or “below,” as in hypodermic, below the skin. It also means “less than normal,” especially in medical terms like hypoglycemia. In the names of chemical compounds, it means “at the lowest state of oxidation,” as in sodium hypochlorite.
What is an example of a hypo?
Hypo is defined as under or less than. An example of hypo used as a prefix is a hypodermic syringe, a needle that injects medicine or fluids under the skin.
What does hypo and hyper mean?
The easiest way to remember the difference is to think of what the prefixes “hyper” and “hypo” mean. Hyper means over/in excess, whereas hypo means under/below. So if you have hyperthyroidism, your thyroid is making too much of the thyroid hormone and your metabolism is running like a cheetah.
How do you know you have a hypo?
Symptoms of a low blood sugar level
- sweating.
- feeling tired.
- dizziness.
- feeling hungry.
- tingling lips.
- feeling shaky or trembling.
- a fast or pounding heartbeat (palpitations)
- becoming easily irritated, tearful, anxious or moody.
What are aptamers used for?
In addition to facilitating biomarker identification, such aptamers can be directly used for cell isolation, cell visualization, and tracking cells in vivo. They can also be used to modulate activities of cell receptors and deliver different agents (e.g., siRNA and drugs) into the cells.
What are polynucleotides in biology?
A polynucleotide is a compound comprised of several nucleotides (as opposed to oligosaccharides comprised of only a few, I.e. about three to twenty). Each monomeric component is comprised, in turn, of a nucleobase, a pentose moiety, and phosphate group.
How big is an oligonucleotide?
Oligonucleotides are small molecules 8–50 nucleotides in length that bind via Watson-Crick base pairing to enhance or repress the expression of target RNA.
How are DNA primers manufactured?
One needs to design primers that are complementary to the template region of DNA. They are synthesized chemically by joining nucleotides together. … Usually a guanine or cytosine is used at the 3′ end, and the 5′ end of the primer usually has stretches of several nucleotides.
How are synthetic DNA primers made?
Synthetic primers are chemically synthesized oligonucleotides, usually of DNA, which can be customized to anneal to a specific site on the template DNA. In solution, the primer spontaneously hybridizes with the template through Watson-Crick base pairing before being extended by DNA polymerase.
How do you synthesize primers?
A primer must be synthesized by an enzyme called primase, which is a type of RNA polymerase, before DNA replication can occur. The synthesis of a primer is necessary because the enzymes that synthesize DNA, which are called DNA polymerases, can only attach new DNA nucleotides to an existing strand of nucleotides.
