Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA along with the instructions it contains is passed from adult organisms to their offspring during reproduction.
DNA or deoxyribonucleic acid is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA) but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
DNA is the chemical name for the molecule that carries genetic instructions in all living things. The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone ma…

[Answer] Double Helix

Answer: A shape like a twisted ladder
Double Helix
Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups.
More Double Helix images
The double helix has not only reshaped biology it has become a cultural icon represented in sculpture visual art jewelry and toys. Researchers working on DNA in the early 1950s used the term “gene” to mean the smallest unit of genetic information but they did not know what a gene actually looked like structurally and chemically or how it was copied with very few errors generation after generation.
Double helix definition is – a helix or spiral consisting of two strands in the surface of a cylinder that coil around its axis; especially : the structural arrangement of DNA in space that consists of paired polynucleotide strands stabilized by cross-links between purine and pyrimidine bases.

Double helix is the biological term that describes the overall structure of DNA. Its double helix consists of two spiral chains of DNA. This double helix shape is often visualized as a spiral staircase.

Histone. A histone is a protein that provides structural support to a chromosome. In order for very long DNA molecules to fit into the cell nucleus they wrap around complexes of histone proteins giving the chromosome a more compact shape. Some variants of histones are associated with the regulation of gene expression.
Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition histones play important roles in gene regulation and DNA replication. Without histones unwound DNA in chromosomes would be very long. For example each human cell has about 1.8 meters of DNA if completely stretched out however when wound about histones …

Histones are highly conserved and are subgrouped into core histones and linker histones . The core histones include histones H2A H2B H3 and H4 and two of each core histones are assembled into an octamer to form the core particle of a nucleosome with 147 bp of DNA wrapped around it (Figure 9.1). 15 The linker histones known as the H1 family sit on the entry and exit sites of the DNA to …
The past year has seen major advances in our understanding of histone and nucleosome structure and function. Direct DNA mapping and thermodynamic experiments have finally provided conclusive evidence that the histones impose an altered helical pitch on the DNA as it is wrapped on the surface of the …

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However many genes do not code for proteins. In humans genes vary in size from a few hundred DNA bases to more than 2 million bases.
The gene is the basic physical unit of inheritance. Genes are passed from parents to offspring and contain the information needed to specify traits. Genes are arranged one after another on structures called chromosomes. A chromosome contains a single long DNA molecule only a portion of which corresponds to a single gene.

Gene integrates information from a wide range of species. A record may include nomenclature Reference Sequences (RefSeqs) maps pathways variations phenotypes and links to genome- phenotype- and locus-specific resources worldwide.
Gene duplications and losses within a family are common and represent a major source of evolutionary biodiversity. Sometimes gene duplication may result in a nonfunctional copy of a gene or a functional copy may be subject to mutations that result in loss of function; such nonfunctional genes are called pseudogenes.: 7.6

[Answer] Uracil

Answer: The base that pairs with Adenine in RNA
Uracil
Uracil is a common and naturally occurring pyrimidine nucleobase in which the pyrimidine ring is substituted with two oxo groups at positions 2 and 4. Found in RNA it base pairs with adenine and replaces thymine during DNA transcription.
Uracil ( / ˈjʊərəsɪl /) ( symbol U or Ura) is one of the four nucleobases in the nucleic acid RNA that are represented by the letters A G C and U. The others are adenine (A) cytosine (C) and guanine (G). In RNA uracil binds to adenine via two hydrogen bonds. In DNA the uracil nucleobase is replaced by thymine.
See more videos for Uracil
Uracil is a nucleotide much like adenine guanine thymine and cytosine which are the building blocks of DNA except uracil replaces thymine in RNA. So uracil is the nucleotide that is found almost exclusively in RNA. Lawrence C. Brody Ph.D.
Uracil can base pair with any of the bases depending on how the molecule arranges itself on the helix but readily pairs with adenine because the methyl group is repelled into a fixed position. Uracil is the hydrogen bond acceptor and can form up to three hydrogen bonds. Uracil can also bind with a ribose sugar to form a ribonucleoside uridine …
Uracil definition is – a pyrimidine base C4H4N2O2 that is one of the four bases coding genetic information in the polynucleotide chain of RNA.

[Answer] Cytosine

Answer: The base that pairs with Guanine in DNA
Cytosine
Cytosine is an aminopyrimidine that is pyrimidin-2-one having the amino group located at position 4. It has a role as a human metabolite an Escherichia coli metabolite a Saccharomyces cerevisiae metabolite and a mouse metabolite. It is a pyrimidine nucleobase a pyrimidone and an aminopyrimidine.
More Cytosine images
Cytosine (/ ˈ s aɪ t ə ˌ s iː n -ˌ z iː n -ˌ s ɪ n /) (symbol C or Cyt) is one of the four nucleobases found in DNA and RNA along with adenine guanine and thymine (uracil in RNA). It is a pyrimidine derivative with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2).
See more videos for Cytosine
Cytosine . Cytosine (C) is one of four chemical bases in DNA the other three being adenine (A) guanine (G) and thymine (T). Within the DNA molecule cytosine bases located on one strand form chemical bonds with guanine bases on the opposite strand. The sequence of four DNA bases encodes the cell’s genetic instructions.
Cytosine definition is – a pyrimidine base C4H5N3O that codes genetic information in the polynucleotide chain of DNA or RNA.
Cytosine and uracil nucleotides are readily mercurated by heating at 37 to 50° C with mercuric acetate in buffered aqueous solutions (p…
