What is a nucleic acid?
Typically, a nucleic acid is a large molecule made up of a string, or “polymer,” of units called “ nucleotides .”. All life on Earth uses nucleic acids as their medium for recording hereditary information – that is nucleic acids are the hard drives containing the essential blueprint or “source code” for making cells.
Why are scientists using nucleic acids?
In fact, scientists are using these molecules to build the basis of an “artificial life form”, which could maintain the artificial nucleic acid and extract information from it to build new proteins and survive. Generally speaking, nucleic acids themselves differ in every organism based on the sequence of nucleotides within the nucleic acid.
How do nucleic acids differ?
Generally speaking, nucleic acids themselves differ in every organism based on the sequence of nucleotides within the nucleic acid. This sequence is “read” by cellular machinery to connect amino acids in the correct sequence, building complex protein molecules with specific functions.

It’s these RNA copies of genetic information which are sent out ...
What type of nucleic acid is used to carry instructions from generation to generation?
Later experiments revealed that another type of nucleic acid – RNA, or ribonucleic acid – acted as a “ messenger ” that could carry copies of the instructions found in DNA. Ribonucleic acid was also used to pass down instructions from generation to generation by some viruses.
What is the function of nucleic acids?
What Is the Main Function of Nucleic Acids? Nucleic acids are biochemical macromolecules that store and transfer genetic information in the cell. They use their stored genetic information to direct the synthesis of new proteins in the cell. New proteins can be synthesized by the ribosomes from the DNA and genes held in the nucleic acids.
Why are nucleic acids important?
The nucleic acids are an important part of the chromosomes because they hold all the genes that comprise the DNA of the organism. The DNA constantly directs and maintains the organism's health and internal environment by directing the production of proteins, which directs the production of hormones, other proteins and enzymes.

What are the nucleic acids?
The nucleic acids, DNA and RNA, may be thought of as the information storage molecules of the cell. In this section, we will examine the structures of DNA and RNA, and how these structures are related to the functions these molecules perform.
What is the role of RNA in cellular reactions?
Catalytic RNAs, called ribozymes, catalyze important cellular reactions, including the formation of peptide bonds in ribosomes (Figure 2.114). DNA, which is usually present in cells in strictly duplex forms (no tertiary structure, per se), is not known to be involved in catalysis.
Why is uracil different from DNA?
Base pairing in RNA is slightly different than DNA. This is due to the presence of the base uracil in RNA in place of thymine in DNA. Like thymine, uracil forms base pairs with adenine, but unlike thymine, uracil can, to a limited extent, also base pair with guanine, giving rise to many more possibilities for pairing within a single strand of RNA.
What is the structure of RNA?
The structure of RNA (Figure 2.137) is very similar to that of a single strand of DNA. Built of ribonucleotides, joined together by the same sort of phosphodiester bonds as in DNA, RNA uses uracil in place of thymine. The building of messenger RNAs by copying a DNA template is a crucial step in the transfer of the information in DNA to a form that directs the synthesis of protein. Additionally, ribosomal and transfer RNAs serve important roles in “reading” the information in the mRNA codons and in polypeptide synthesis. RNAs are also known to play important roles in the regulation of gene expression.
What is the role of RNA in catalysis?
The discovery, in 1990, that RNAs could play a role in catalysis, a function once thought to be solely the domain of proteins, was followed by the discovery of many more so-called ribozymes- RNAs that functioned as enzymes. This suggested the answer to a long-standing chicken or egg puzzle – if DNA encodes proteins, but the replication of DNA requires proteins, how did a replicating system come into being? This problem could be solved if the first replicator was RNA, a molecule that can both encode information and carry out catalysis. This idea, called the “RNA world” hypothesis, suggests that DNA as genetic material and proteins as catalysts arose later, and eventually prevailed because of the advantages they offer. The lack of a 2’OH on deoxyribose makes DNA more stable than RNA. The double-stranded structure of DNA also provides an elegant way to easily replicate it. RNA catalysts, however, remain, as remnants of that early world. In fact, the formation of peptide bonds, essential for the synthesis of proteins, is catalyzed by RNA.
Why does adding phosphates to a nucleoside monophosphate require energy?
Addition of second and third phosphates to a nucleoside monophosphate requires an input of energy, due to the repulsion of negatively charged phosphates. This chemical energy can be released in the reverse reaction. This conversion of triphosphate nucleotides (such as ATP) to diphosphates is a reaction that is employed for energy storage and utilization by cells.
How many hydrogen bonds are there in DNA?
Hydrogen bonds between the base pairs hold a nucleic acid duplex together, with two hydrogen bonds per A-T pair (or per A-U pair in RNA) and three hydrogen bonds per G-C pair. The B-form of DNA has a prominent major groove and a minor groove tracing the path of the helix (Figure 2.132). Proteins, such as transcription factors bind in these grooves and access the hydrogen bonds of the base pairs to “read” the sequence therein.
