    Study Notes

    Nucleic Acids Structure in Molecular Biology

    • Molecular biology deals with biological phenomena at the molecular level, including DNA and RNA, proteins, and other macromolecules involved in genetic information and cell function.
    • Nucleic acids are polymers of nucleotides, with two main types: deoxyribonucleic acids (DNA) and ribonucleic acids (RNA).
    • DNA stores the genetic information that controls all cellular processes and is responsible mainly for storage and transfer of information needed for production of proteins.
    • DNA consists of two strands of polynucleotides, with a primary structure that describes the sequence of nucleotides in each strand.
    • The nucleotides that form DNA primary structure are mainly four: dAMP, dGMP, dCMP, and dTMP.
    • The two strands of DNA are paired to each other and coil around a common axis to form a right-handed helix, known as the B-form of DNA.
    • The two strands are held together by complementary base pairing through specific hydrogen bonds, with adenine pairing with thymine and guanine pairing with cytosine.
    • The base pairs inside the helix are stacked above each other by Van der Waals forces and hydrophobic interactions, providing the stability of the double helix.
    • The B-form of DNA is 2 nm wide, with two grooves, a major and a minor groove, through which many drugs and proteins can contact the nitrogenous bases without opening the helix.
    • There are three major structural forms of DNA: the B-form, the A-form, and the Z-form.
    • DNA is mainly linear or sometimes circular, and the packing of large DNA molecules into cells requires a process called “DNA supercoiling.”
    • Mitochondrial DNA forms 0.3 to 1% of the total cellular DNA and is responsible for controlling the synthesis of 2 rRNA, 22 tRNA, and 13 proteins, mostly involved in oxidative phosphorylation.

    Nucleic Acids Structure in Molecular Biology

    • Molecular biology deals with biological phenomena at the molecular level, including DNA and RNA, proteins, and other macromolecules involved in genetic information and cell function.
    • Nucleic acids are polymers of nucleotides, with two main types: deoxyribonucleic acids (DNA) and ribonucleic acids (RNA).
    • DNA stores the genetic information that controls all cellular processes and is responsible mainly for storage and transfer of information needed for production of proteins.
    • DNA consists of two strands of polynucleotides, with a primary structure that describes the sequence of nucleotides in each strand.
    • The nucleotides that form DNA primary structure are mainly four: dAMP, dGMP, dCMP, and dTMP.
    • The two strands of DNA are paired to each other and coil around a common axis to form a right-handed helix, known as the B-form of DNA.
    • The two strands are held together by complementary base pairing through specific hydrogen bonds, with adenine pairing with thymine and guanine pairing with cytosine.
    • The base pairs inside the helix are stacked above each other by Van der Waals forces and hydrophobic interactions, providing the stability of the double helix.
    • The B-form of DNA is 2 nm wide, with two grooves, a major and a minor groove, through which many drugs and proteins can contact the nitrogenous bases without opening the helix.
    • There are three major structural forms of DNA: the B-form, the A-form, and the Z-form.
    • DNA is mainly linear or sometimes circular, and the packing of large DNA molecules into cells requires a process called “DNA supercoiling.”
    • Mitochondrial DNA forms 0.3 to 1% of the total cellular DNA and is responsible for controlling the synthesis of 2 rRNA, 22 tRNA, and 13 proteins, mostly involved in oxidative phosphorylation.
