Lecture 10 - DNA Structure

Flashcards focusing on key concepts and facts from Lecture 10 on DNA Structure.

DNA is structured as a __ helical molecule.

double stranded

The main components of DNA include __, phosphate groups, and nitrogenous bases.

nucleotides

According to Chargaff's Rules, [A] = and [G] = .

[T]; [C]

DNA strands are joined together by __ bonds to form a polynucleotide.

phosphodiester

Nucleotide monomers are synthesised in the __ direction.

5´ to 3´

The two strands of DNA are __, meaning they run in opposite directions.

antiparallel

The bases of the DNA molecule are located on the __ of the helical structure.

inside

Semi-conservative replication allows genetic information to be passed to the __ generation.

next

The sugar phosphate backbone of DNA is located on the __ of the helix.

outside

The Watson-Crick model of DNA helped propose a possible __ mechanism for genetic material.
