What is nucleic acid synthesis?
Nucleic acids are the polymers of nucleotides. Nucleotide synthesis is an anabolic mechanism generally involving the chemical reaction of phosphate, pentose sugar, and a nitrogenous base. Destruction of nucleic acid is a catabolic reaction.
What are nucleic acids PPT?
NNuucclleeiicc AAcciiddss Nucleic acids are molecules that store information for cellular growth and reproduction There are two types of nucleic acids: – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) These are polymers consisting of long chains of monomers called nucleotides A nucleotide consists of a …
Which of the following result from mismatched or unmatched bases in the a form helix of RNA?
Breaks in the regular A-form RNA double helix caused by mismatched or unmatched bases in one or both strands are common and result in bulges or internal loops (Fig. 8-23a). Hairpin loops form between nearly self-complementary (palindromic) sequences.
What is nucleic acid slide share?
NUCLEIC ACID • Nucleic acid are polymers that consist of nucleotide residues. • Located in nuclei of cell • Hereditary determinants of living organisms • Elemental composition – carbon, hydrogen, oxygen, nitrogen and phosphorus. TYPES OF NUCLEIC ACID • Deoxyribonucleic acid (DNA) • Ribonucleic acid (RNA)
What is inhibition of nucleic acid synthesis?
Quinolones are a key group of antibiotics that interfere with DNA synthesis by inhibiting topoisomerase, most frequently topoisomerase II (DNA gyrase), an enzyme involved in DNA replication. This allows the DNA strand to be replicated by DNA or RNA polymerases. …
Where are nucleotides Synthesised?
the liver
Nucleotides are obtained in the diet and are also synthesized from common nutrients by the liver. Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates.
What is DNA Slideshare?
DNA DNA or deoxyribonucleic acid is a genetic material that transfer the genetic information from one organism to their off spring. Located in nucleus and mitochondria The information in DNA is stored as code (made up of A,G,C,T). 99% of base are same . The order of bases determines the individuality.
What is nucleic acid in biochemistry?
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 nucleic acids good for?
Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
What is the biological importance of nucleic acids?
Nucleic acid is an important class of macromolecules found in all cells and viruses. The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.
What is nucleic acid BYJU’s?
Nucleic acids are long-chain polymeric molecules, the monomer (the repeating unit) is known as the nucleotides and hence sometimes nucleic acids are referred to as polynucleotides. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are two major types of nucleic acids.

What is nucleic acid?
NUCLEIC ACID • Nucleic acid are polymers that consist of nucleotide residues. • Located in nuclei of cell • Hereditary determinants of living organisms • Elemental composition – carbon, hydrogen, oxygen, nitrogen and phosphorus
Where does protein synthesis occur in the cell?
Translation: Protein Synthesis • The synthesis of proteins occur at ribosomes, which are outside the nucleus and within the cytoplasm of cells • The mRNA connects with the ribosome, and the amino acids attached to transfer RNA are delivered one by one • Protein synthesis, or translation, takes place in three steps: • 1.
When was nucleic acid first discovered?
HISTORIC RESUME Friedrich Miescher in 1869 • Isolated what he called nuclein from the nuclei of pus cells • Nuclein was shown to have acidic properties, hence it became called nucleic acid 3. NUCLEIC ACID • Nucleic acid are polymers that consist of nucleotide residues.
Where are nucleic acids found in the eukaryotic cell?
The distribution of nucleic acids in the eukaryotic cell • DNA is found in the nucleus with small amounts in mitochondria and chloroplasts • RNA is found throughout the cell 6. NUCLEIC ACID STRUCTURE • Nucleic acids are polynucleotides • Their building blocks are nucleotides 7.
