Description
|
| Meiosis
|
A process within the cell nucleus that results in the reduction of the chromosome number from diploid (two copies of each chromosome) to haploid (a single copy) through two reductive divisions in germ cells. |
| Mitosis
|
The nuclear division that results in the replication of the genetic material and its redistribution into each of the daughter cells during cell division. |
| Multiple alignment
|
An alignment of three or more sequences, with gaps inserted in the sequences such that residues with common structural position and/or ancestral residues are aligned in the same column of a multiple alignment. |
| Messenger RNA (mRNA):
|
The complementary RNA copy of DNA formed from a single-stranded DNA template during transcription that migrates from the nucleus to the cytoplasm where it is processed into a sequence carrying the information to code for a polypeptide domain. |
| Motif
|
A conserved element of a protein sequence alignment that usually correlates with a particular function. Motifs are generated from a local multiple protein sequence alignment corresponding to a region whose function or structure is known. It is sufficient that it is conserved, and is hence likely to be predictive of any subsequent occurrence of such a structural/functional region in any other novel protein sequence. |
| Match
|
In sequence alignment, the existence of the same base in a homologous position in both sequences. |
| Mismatch
|
A position in a double-stranded DNA molecule where base-pairing does not occur because the nucleotides are not complementary. |
