DNA Structure

DNA Structure. DNA Structure. DNA consists of two molecules that are arranged into a ladder-like structure called a Double Helix . A molecule of DNA is made up of millions of tiny subunits called Nucleotides . Each nucleotide consists of: Phosphate group Pentose sugar Nitrogenous base.

Comparison of RNA and DNA

Comparison of RNA and DNA. What makes tRNA?. a) Amino acid which is specific to each tRNA. (b) CCA base sequence to which the amino acid is attached by the 'Activating Enzyme'. (c) Complementary base pairing sequence. Helical in shape. (d) 8 free bases non-pairing giving one loop of RNA.

Protein Synthesis

Protein Synthesis. With thanks to Jenny P. DNA is a very long molecule that looks like a twisted ladder. It is made up of 4 different subunits called nucleotides which can be arranged in any order. The bases are complementary. DNA has two strands.
