Readers ask: What Type Of Molecule Is Dna Quizlet?

What is DNA composed of? DNAis a nucleic acid made up of nucleotides joined into long strands or chains by covalent bonds.

What type of molecule is DNA?

DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T).

What kind of molecule is DNA quizlet?

DNA is a nucleic acid with deoxyribose sugar and phosphate as the backbone. It is the molecule that provides the blueprint for all living organisms to develop, live and reproduce. The building blocks of DNA, nucleotide monomers are organic compounds made up of a nitrogenous base, a sugar, and a phosphate group.

Is DNA A biology or A chemical?

Deoxyribonucleic acid (DNA) is an organic chemical that contains genetic information and instructions for protein synthesis. It is found in most cells of every organism. DNA is a key part of reproduction in which genetic heredity occurs through the passing down of DNA from parent or parents to offspring.

What is the chemistry 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.

What is the DNA quizlet?

Deoxyribonucleic Acid; A nucleic acid found in the nucleus of all living cells, which carries the organism’s hereditary information.

What is DNA and RNA quizlet?

A double-stranded nucleic acid that contains the genetic information for cell growth, division, and function. The set of DNA and RNA sequences that determine the amino acid sequences used in the synthesis of an organism’s proteins. It is the biochemical basis of heredity and nearly universal in all organisms.

What DNA contains quizlet?

They both contain the nucleotides Adenine, Cytosine, and Guanine. DNA contains the nucleotide Thymine, where as, RNA contains the nucleotide Uracil.

Is DNA A nucleic acid?

​Nucleic Acid Nucleic acid is an important class of macromolecules found in all cells and viruses. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.

What is the structure of A DNA molecule?

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 made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), and thymine (T).

Why is DNA an organic molecule?

A nucleic acid is an organic compound, such as DNA or RNA, that is built of small units called nucleotides. Many nucleotides bind together to form a chain called a polynucleotide. The nucleic acid DNA (deoxyribonucleic acid) consists of two polynucleotide chains.

What are the chemical components of a DNA molecule?

What are the chemical components of a DNA molecule? DNA is composed of a sequence of subunits, each containing a phosphate, a deoxyribose sugar, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G), or cytosine (C).

Is DNA A compound or mixture?

Nucleic Acids. A nucleic acid is an organic compound, such as DNA or RNA, that is built of small units called nucleotides. Many nucleotides bind together to form a chain called a polynucleotide. The nucleic acid DNA (deoxyribonucleic acid) consists of two polynucleotide chains.

What is the molecular structure of DNA and RNA?

Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell’s activities, while RNA converts that code into proteins to carry out cellular functions.
