What makes the sides of dna




















Makes up the sides of the DNA 'ladder', alternating sugar-phosphate-sugar-phosphate. The backbone of a DNA molecule consists of the phosphate groups and the deoxyribose sugars, whereas the base region of the DNA molecule consists of the nitrogenous bases; therefore, the backbone of DNA is made up of phosphate groups and pentose sugars. A nucleotide consists of three things: A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine in the case of RNA, thymine is replaced by uracil.

A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons. One or more phosphate groups.

DNA stands for. You just studied 11 terms! Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups both within each component and between components. Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing. DNA is such an important process because if DNA replication did not occur, then when the cells divide, there would not be an exact replica of the DNA in each cell.

This would cause many problems within the human body. Extend your thinking : Sometimes errors called mutations occur during DNA replication. The separation of the two single strands of DNA creates a 'Y' shape called a replication 'fork'.

The two separated strands will act as templates for making the new strands of DNA. DNA has three types of chemical component : phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine.

Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine. DNA is made up of molecules called nucleotides. Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix.

If you think of the double helix structure as a ladder, the phosphate and sugar molecules would be the sides, while the bases would be the rungs. The double helix is a description of the molecular shape of a double-stranded DNA molecule. The phosphate and deoxyribose molecules form the sides of the DNA ladder while nitrogenous bases form the rungs. The size of a gene may vary greatly, ranging from about 1, bases to 1 million bases in humans.

Genes only make up about 1 percent of the DNA sequence. DNA sequences outside this 1 percent are involved in regulating when, how and how much of a protein is made. DNA's instructions are used to make proteins in a two-step process. First, enzymes read the information in a DNA molecule and transcribe it into an intermediary molecule called messenger ribonucleic acid, or mRNA. Next, the information contained in the mRNA molecule is translated into the "language" of amino acids, which are the building blocks of proteins.

This language tells the cell's protein-making machinery the precise order in which to link the amino acids to produce a specific protein. This is a major task because there are 20 types of amino acids, which can be placed in many different orders to form a wide variety of proteins. But nearly a century passed from that discovery until researchers unraveled the structure of the DNA molecule and realized its central importance to biology. For many years, scientists debated which molecule carried life's biological instructions.

Most thought that DNA was too simple a molecule to play such a critical role. Instead, they argued that proteins were more likely to carry out this vital function because of their greater complexity and wider variety of forms. By studying X-ray diffraction patterns and building models, the scientists figured out the double helix structure of DNA - a structure that enables it to carry biological information from one generation to the next.

Despite his scientific achievements, Dr. Scientist use the term "double helix" to describe DNA's winding, two-stranded chemical structure. This shape - which looks much like a twisted ladder - gives DNA the power to pass along biological instructions with great precision. To understand DNA's double helix from a chemical standpoint, picture the sides of the ladder as strands of alternating sugar and phosphate groups - strands that run in opposite directions.

Each "rung" of the ladder is made up of two nitrogen bases, paired together by hydrogen bonds. Write your answer Related questions. Part of the nucleotide that makes up the side of the DNA ladder?
