What is DNA in simple sentence?
What is DNA in simple sentence?
Meaning: [ˌdiːenˈeɪ] n. (biochemistry) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix; associated with the transmission of genetic information. 1) DNA fingerprinting has proved the clincher in this investigation.
What is the meaning of deoxyribonucleic?
Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix.
What is a sentence for RNA?
Rna sentence example. Viruses represent a large group of infective agents that are composed of a core of nucleic acids, either RNA or DNA, surrounded by a layer of protein.
How do you use guanine in a sentence?
Guanine sentence example The enzyme is modulated by adenine and guanine nucleotides, although it is difficult to make much sense of the observed effects. Cytosine and guanine are two of the four molecules, called nucleic acids, that make up DNA.
How is DNA used in everyday life?
In all living things, DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal develops and reproduces, and eventually dies. Human cells normally contain 23 pairs of chromosomes, for a total of 46 chromosomes in each cell.
What is an example of deoxyribonucleic acid?
DNA outside the nucleus is referred to as extranuclear DNA. Examples of extranuclear DNAs are mitochondrial DNA (mtDNA) and chloroplast DNA (cpDNA).
What is deoxyribonucleic acid used for?
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
What is a sentence for amino acid?
Silk is a naturally moist and amino-acid based fabric that can be dried out by such measures. This essential amino acid is vital in the make up of critical body proteins.
What is RNA and DNA?
Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA.
How do you use thymine in A sentence?
The tanning activator coumarin is known to induce thymine dimers (cyclobutane pyrimidine dimers). This example is from Wikipedia and may be reused under a CC BY-SA license. It most commonly pairs with thymine as an adenine-analogue, but can also pair with cytosine as a guanine-analogue;.
Is cytosine part of DNA?
Cytosine (C) is one of the four nucleotide bases in DNA, with the other three being adenine (A), guanine (G) and thymine (T). Within a double-stranded DNA molecule, cytosine bases on one strand pair with guanine bases on the opposite strand.
What are examples of DNA?
DNA outside the nucleus is referred to as extranuclear DNA. Examples of extranuclear DNAs are mitochondrial DNA (mtDNA) and chloroplast DNA (cpDNA). The presence of nucleic acids in these organelles enables them to become semi-autonomous, self-reproducing organelles.
How DNA is used in medicine?
Advances in genetic engineering influence to an increasing extent a number of medical disciplines. DNA analysis can be used in the diagnosis of hereditary diseases, in investigations of malignant processes, in forensic medicine and for detection of infectious pathogens.
What is the use of deoxyribonucleic acid DNA in our body?
What does DNA do? DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Why is it called deoxyribonucleic acid?
The ‘deoxyribo’ part corresponds to the pentose sugar it is composed of which is bound to its base while the nucleic acid corresponds to the bases and phosphate. The deoxyribose is missing an OH-group at position 2 of the sugar ring. Hence, the name literally indicates ‘lack of oxygen’.
Where is deoxyribonucleic acid found?
As described above, DNA can be found in three organelles: the nucleus, mitochondrion, and chloroplast. Only eukaryotes have a nucleus, which is a large structure that’s surrounded by a membrane. Nuclear DNA comes in the form of long, linear pieces of DNA called chromosomes.
How do you use nucleic acid in a sentence?
Nucleic sentence example
- It appears to be a combination of a protein with nucleic acid.
- Cytosine and guanine are two of the four molecules, called nucleic acids, that make up DNA.
- The enediyne chromophores are interesting because of their ability to bind and cleave nucleic acids resulting in potent anti-cancer activity.
How do you use hormone in a sentence?
1 Hormone implants are used as growth boosters. 2 Testosterone is the male sex hormone. 3 Extra doses of the hormone caused the animals’ reproductive organs to develop sooner than usual. 4 This hormone interacts closely with other hormones in the body.
What is the DNA function?
The function of DNA is to store all of the genetic information that an organism needs to develop, function, and reproduce. Essentially, it is the biological instruction manual found in each of your cells.
