Example sentences for: cytosine
How can you use “cytosine” in a sentence? Here are some example sentences to help you improve your vocabulary:
MeCP2's functional structure consists of an 84 amino acid methyl-binding domain (MBD) [ 11 ] and a 104 amino acid transcriptional repression domain (TRD) [ 12 ] . The MBD is able to bind to 5-methyl cytosine residues of a single CpG dinucleotide [ 11 ] . Under the current model, MeCP2 binds to DNA, then complexes with Sin3A through the TRD and recruits histone deacetylases (HDAC).
It has previously been observed that a mutation in the Zn(II) binding motif can affect the cleavage site selectivity of topoisomerase I [ 32 ] even though Top67 by itself can recognize both the cytosine in the -4 position and the junction of single- and double-stranded DNA.
A number of studies have evaluated possible associations between a polymorphism in the cytochrome P450c17α ( CYP17 ) gene and breast cancer risk [ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ] . Cytochrome P450c17α functions at key branch points in human steroidogenesis, catalyzing the ovarian and adrenal biosynthesis pathways for androstenedione, the immediate precursor of testosterone [ 17 ] . Three polymorphisms have been described in this gene: a C → T transition at nucleotide 5471 in intron 6 [ 18 ] , a G → A transition at nucleotide 47 in the 5'-untranslated region promoter [ 19 ] , and a thymidine substitution for cytosine at nucleotide 27 in the 5'-untranslated region promoter that creates a Msp AI recognition site [ 20 ] .
Several gene family members, including Cpn 008, 010, 043, 1054, and 1055, contain homopolymeric cytosine repeats either upstream or at the predicted 5' end of the coding region.
To suppress glial growth, cultures were treated with cytosine β-D-arabinofuranoside (10 -5M) after 3 days in vitro . All cultures were maintained in an incubator (5% CO 2 ; 37°C) for at least 6 days and no more than 10 days prior to use.
