A base found in DNA and RNA and derived from pyrimidine; pairs with guanine.
1 Water stress is known to alter cytosine methylation, which generally represses transcription.
2 Thus, cytosine - to- uracil editing may contribute to the sequence diversification of many viruses.
3 The majority of cytosine methylation in mammals resides in repetitive DNA sequences.
4 Compared to thymine-thymine carriers, cytosine allele carriers have a higher subjective happiness level.
5 The enzyme is not affected by cytosine methylation in hemimethylated DNA.
6 These clusters represent potential alternate nucleobase pairs, geometrically equivalent to guanine - cytosine .
7 Regression analysis indicated that the cytosine allele is significantly associated with subjective happiness level.
8 Cloning and sequencing revealed HCA-7 to have eight cytosine residues in this repeat sequence.
9 This analysis confirmed that older people have a lower amount of cytosine methylation than newborns.
10 There are two ways for uracil to appear in DNA: thymine replacement and cytosine deamination.
11 It was concluded that the regulation of cytosine ethylation mechanisms was disturbed in the mutants.
12 DNA methylation is an epigenetic modification of DNA that adds a methyl group to cytosine .
13 Similarly, cytosine is the preferred binding partner for the Watson-Crick face of the para adduct.
14 In addition, these results suggest that cytosine methylation may play a role in human DNA repair.
15 This schematic represents a portion of the nucleotides-inthis case cytosine , adenine, and guanine-fromthe Grayson genome.
16 Fludarabine has the effect of increasing the triphosphate form of cytosine arabinoside in acute and chronic leukemic cells.
