Definitions
Below is a directory of terms used in the field of genetically modified crops. Most of the terms have been reproduced from the University of California Biotech [UCB] or John Innes Centre [JIC].
Producing enough food for a rapidly growing population, and taking care of our planet are two of the world's biggest challenges.
C
Chromosome
A thread-like structure, consisting mostly of DNA and supporting proteins, that contains the genetic information (in the form of genes) that instruct the cell on its function. Genes are arranged in a particular order on chromosomes. Chromosomes are found in the nucleus of the cell and organisms contain differing but characteristic numbers of chromosomes, which are arranged in pairs in 'higher' plants and animals.
Cloning
Means of isolating particular parts of the genome as small fragments of DNA, and making copies of and studying the sequence in another organism. Can also mean the process of producing, by non-sexual means, an identical copy of an organism. [UCB]
