This means that one strand's sugar-phosphate chain runs in the 5' to 3' direction ... pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new ...

In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these ... and a variable component called a side chain (see below). Within a protein, multiple ...

forming a long chain. In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G with C) to form the iconic double helix structure. RNA is ...

This diagram depicts the chemical structure of pyrimidine ... thereby suppressing the immune response. Polymerase Chain Reaction is a widely used technique in molecular biology for amplifying specific ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed into ... between the adjacent amino acids to finalise the structure.
