Number sequences are sets of numbers that follow a pattern or a rule. If the rule is to multiply or divide by a specific number each time, it is called a geometric sequence. Each term in a ...

For this challenge you'll be presented with a sequence of different shapes. To solve the puzzle you will need to identify which missing shape completes the sequence. It may help to have a pencil ...

The folded shape, or conformation, depends directly on the linear amino acid sequence of the protein. The building blocks of proteins are amino acids, which are small organic molecules that ...

Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...
