Nucleic Acids

Nucleic Acids are

• DNA and RNA

• Polynucleotides

• Polymers

• All of these

Building blocks of nucleic acid are

• Nitrogen bases

• Nucleoside

• Nucleotide

• Amino acid

Nucleotide of adenine bis called

• Adenine

• Adenosine

• Adenylic acid

• Adenine sugar

Deoxyribose sugar is present in

• DNA only

• RNA only

• DNA and RNA

• t-RNA

DNA consist of

• Phosphate

• Deoxyribose sugar

• A, T, G ,C

• A, U, G, C

In nucleic acids, nucleotides are connected with each other by

• Phosphate bond

• Phoshpo diester bond

• Peptide bond

• Ester bond

..... are examples of purine bases

• Adenine and Guanine

• Thymine and Cytosine

• Adenine only

• Guanine only

Most accepted model of DNA was proposed by

• Watson and Crick

• Jacob and Monad

• Korenberg

• Frederick Mischer

Protein synthesis is main function of

• t-RNA

• r-RNA

• m-RNA

• All types of RNA

In eukaryotes, DNA is mainly present in

• Nucleus

• Cytoplasm

• Ribosome

• Golgi Complex
