C. elegans genome: All of the genetic information contained in the roundworm Caenorhabditis elegans (C. elegans).
The genomes of particular nonhuman organisms such as C. elegans have been studied for a number of reasons including the need to improve sequencing and analysis techniques. These nonhuman genomes also provide powerful sets of data against which to compare the human genome.
For example, human genes that contribute to Alzheimer’s disease and colon cancer have counterpart genes in C. elegans. And at least 100 genes that regulate human fat metabolism have counterpart genes in C. elegans.
The C. elegans genome contains 97 million base pairs and is estimated to have 19,099 genes. The sequencing of this genome was completed in 1998.
- C1 (cervical vertebra)
C1 (cervical vertebra): C1 is the first cervical (neck) vertebra which is called the atlas. It supports the head. The atlas bone is named for the Greek god Atlas who was condemned to support the earth and its heavens on his shoulders. (Because the god Atlas often adorned maps, a compilation of maps came to […]
- C1-C7 (cervical vertebrae)
C1-C7 (cervical vertebrae): C1 through C7 are the symbols for the cervical (neck) vertebrae, the upper 7 vertebrae in the spinal column (the vertebral column). C1 is called the atlas. It supports the head and is named for the Greek god Atlas who was condemned to support the earth and its heavens on his shoulders. […]
- C2 (cervical vertebra)
C2 (cervical vertebra): C2 is the symbol for the second cervical vertebra, which is also called the axis. It is so-named because the uppermost cervical vertebra (called the atlas) rotates about the odontoid process of the second cervical vertebra. The joint between the axis and atlas is a pivot type of joint. It allows the […]
- C3 (cervical vertebra)
C3 (cervical vertebra): The third cervical (neck) vertebra from the top.
- C4 (cervical vertebra)
C4 (cervical vertebra): The fourth cervical (neck) vertebra from the top.
