- n. Plural form of tetranucleotide.
Sorry, no etymologies found.
Microsatellite polymorphisms (Section 7.4.3) are based on short tandem repeats, usually di -, tri - or tetranucleotides.
The prevailing theory was that there were two purines and two pyrimidines in each tetranucleotide and that these tetranucleotides were strung together in some fashion.
Because the two tetranucleotides are similar, with the exception that the most 3′-end of the upstream sequence is A (− 42) the corresponding position of the downstream sequence is G (− 31), we examined the effect of base substitution of the G at position − 31.
The G residue in the second position is the most critical among the tetranucleotides AGCA and AGCG.
