Complete the sentences to describe the structure of DNA. The shape of the DNA molecule is called a double . The backbone of DNA is made of molecules and phosphate molecules. The "rungs" of DNA are made of .
Answer:
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). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.
DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.
An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.
DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.
The National Human Genome Research Institute (NHGRI), a part of the National Institutes of Health (NIH), provides a fact sheet Deoxyribonucleic Acid (DNA) that gives an introduction to this molecule.
StatedClearly offers a video introduction to DNA and how it works.
The New Genetics, a publication of the National Institute of General Medical Sciences, part of the NIH, discusses the structure of DNA and how it was discovered.
A basic explanation and illustration of DNA can be found on Arizona State University's "Ask a Biologist" website.
The Virtual Genetics Education Centre, created by the University of Leicester, offers additional information on DNA, genes, and chromosomes.
An overview of mitochondrial DNA is available from the Neuromuscular Disease Center at Washington University in St. Louis.
The shape of the DNA molecule is called a double helix. The backbone of DNA is made of sugar molecules and phosphate molecules. The "rungs" of DNA are made of four nitrogen bases that are adenine, thymine, guanine, cytosine.
What is DNA ?The molecule found inside cells that contain the genetic information necessary for an organism's development and function. DNA molecules enable this information to be passed down from generation to generation.
DNA is made up of a series of molecules known as nucleotides. A nitrogen base, a sugar group, and a phosphate group are all present in each nucleotide. Adenine (A), Thymine (T), Guanine (G), and Cytosine (C) are the four nitrogen bases that can be found in DNA (C). There are billions of DNA bases in human DNA.
It stores instructions for the production of larger molecules known as proteins. These instructions are stored within each of your cells and are distributed across 46 long structures known as chromosomes.
Thus, chromosomes are composed of thousands of shorter DNA segments known as genes.

How does water move between the hydrosphere and atmosphere?
Answer:
Water moves between the hydrosphere and atmosphere through evaporation condensation and precipitation.
Explanation:
Brainliest plz
Water is a renewable resource that is present in the spheres of the earth. The water moves between the hydrosphere and atmosphere through evaporation, condensation, and precipitation.
What are changing states of matter?The different matters can be changed into one another through various methods that include evaporation, condensation, and precipitation. In the water cycle, the water from the hydrosphere gets evaporated from the liquid to the vapor phase.
The evaporated water vapor then condenses and cools down to form and store in the clouds. Then the condensed vapor in the atmosphere collectively comes back to earth in the form of precipitate that can be rain, snow, sleet, hail, etc.
Therefore, the water cycle involves evaporation, condensation, and precipitation to move water between the hydrosphere and the atmosphere.
