What is the structure and function of nucleic acids?
Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
What is the primary structure of a nucleic acid?
The primary structure of the nucleic acid refers to the sequence of its nucleotide bases, and the way these are covalently bonded to each other. The sequence of “letters” in a strand of DNA or RNA, then, is part of its primary structure, as is the helical or double-helical shape.
What is the structure of nucleic acids 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).
What is the structure of nucleotides?
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
What are the 2 main type of nucleic acids?
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 are two types of nucleic acids quizlet?
There are two types of nucleic acid: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
What are the structural units of nucleic acids?
The building block unit of a nucleic acid is called a nucleotide. A nucleotide consists of a single sugar, a phosphate, and a nitrogen-containing base. There are four different bases each in DNA and RNA . Both DNA and RNA contain the bases adenine , guanine , and cytosine.
What are the three components of nucleic acids?
Nucleic acids are chains of nucleotides, which are composed of three parts: a phosphate backbone, a pentose sugar, either ribose or deoxyribose, and one of four nucleobases. An analogue may have any of these altered.
What are some facts about nucleic acids?
Nucleic acids are characterized as very large molecules that have distinctively two main parts, usually noted as the double-helix formation. The helix formation that represents a nucleic acid pattern is unique, one that intends to separate one [family’s] biological identification from another.
What are the differences between the types of nucleic acids?
Nucleic acids are biopolymers composed of millions of monomers called nucleotides. There are two main types of nucleic acids: DNA and RNA. DNA and RNA differ in their compositions. The main difference between DNA and RNA is that DNA contains deoxyribose sugar while RNA contains ribose sugar as indicated by their names.
