a check up

Use this department to check up on the accuracy of your lecture notes. Make sure that you have written down the following definitions, explanations and important concepts in your notes.

Biological Information - Part One


Every living organism is the outward physical manifestation of internally coded, inheritable information.


The phenotype is the outward physical manifestation.


The genotype of an organism is the internally coded, inheritable information.


The genotype and phenotype of a living organism are linked to one another by a simple relationship.

A trait

The phenotype of even the simplest organism on earth is very, very complex. These complex phenotypes can be analyzed by breaking them down into smaller, discrete sections or components called traits.

Why is the flower red?

A plant's flower is part of its reproductive system. Flowers are the sex organs of certain plants and hold the male and female gamete producing systems. Flowers are also where fertilization takes place.

Where does the pigment come from?

Pigment is produced in the petal cells of the plant as the result of a chemical reaction.

The key role of proteins

Proteins play key roles within all cells.

Proteins are macromolecular polymers

Proteins are polymers, long chains of amino acids (the monomers) joined together by peptide bonds.

Genotype codes for protein

The genotype of a cell contains the biological information needed to join amino acids together in the correct sequence to produce an active protein.
