Words similar to cytosine
Example sentences for: cytosine
How can you use “cytosine” in a sentence? Here are some example sentences to help you improve your vocabulary:
The genomes of primates contain a family of nine APOBEC genes that encode enzymes involved in the editing of RNA and/or DNA through the deamination of cytosine (C), so that this nucleotide mutates to uracil (U).
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.
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 ] .
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.
Intermolecular interactions can be precisely predicted by Watson–Crick basepairing (adenine to thymidine and guanine to cytosine).
