What is the nucleic acid that forms?

What is the nucleic acid that forms?

deoxyribonucleic acid (DNA)
Nucleic acids come in two natural forms called deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleic acids are made of biopolymers, which are naturally-occurring, repeated sets of monomers (making polymers) that then create nucleotides, which form nucleic acids.

Can nucleic acids be simple or complex?

Although nucleic acids seem complex, they follow much of the same simple functional group chemistry. Figure 8.22 shows the only two sugars which occur in nucleic acids: β-d-ribose in RNA and β-d-2-deoxyribose in DNA These sugars differ from each other only in the presence or absence of the hydroxyl group at C2.

What are the most common nucleic acids?

The most common types of nucleic acids are:

• deoxyribonucleic acid (DNA)
• ribonucleic acid (RNA)
• messenger RNA (mRNA)
• transfer RNA (tRNA)
• ribosomal RNA (rRNA)

What is the basic structure of nucleic acid?

Basic structure Nucleic acids are polynucleotides—that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.

What are the basic chemical unit of a nucleic acid?

The basic repeating unit of nucleic acids are known as nucleotides. A nucleotide consists of three distinct chemical groups, a 5-carbon sugar (ribose or deoxyribose), a nitrogen-rich base – (cytosine (C), guanine (G), adenine (A), thymine (T) in DNA or uracil (U) instead of T (in RNA), and phosphate.

What is nucleic acid simple?

Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells. They play an especially important role in directing protein synthesis. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

What is the basic structure of a nucleic acid?

Is DNA acidic or basic?

You’re right: DNA is built of both acidic and basic components. The acidic component of DNA is its phosphate group, and the basic component of DNA is its nitrogenous base.

What structure do nucleic acids have quizlet?

What is the structure of nucleic acids? Large monomers (polynucleotides) formed from many nucleotides (the monomers) linked in a chain. Pentose monosaccharide, phosphate group (inorganic molecule that is acidic and negatively charged), nitrogenous base (one or two carbon rings).

Which is the correct description of a nucleic acid?

Nucleic acids RNA (left) and DNA (right). Nucleic acids are the biopolymers, or large biomolecules, essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA. They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.

Who was the first person to discover nucleic acids?

The Swiss scientist Friedrich Miescher discovered nucleic acids (DNA) in 1869. Later, he raised the idea that they could be involved in heredity. Nucleic acids are the biopolymers, or small biomolecules, essential to all known forms of life.

How are sugars and phosphates connected in a nucleic acid?

The sugars and phosphates in nucleic acids are connected to each other in an alternating chain (sugar-phosphate backbone) through phosphodiester linkages. In conventional nomenclature, the carbons to which the phosphate groups attach are the 3′-end and the 5′-end carbons of the sugar.

What makes a double stranded nucleic acid double stranded?

Double-stranded nucleic acids are made up of complementary sequences, in which extensive Watson-Crick base pairing results in a highly repeated and quite uniform Nucleic acid double-helical three-dimensional structure.
