Investigators have been studying an aggregate
containing enzymes of deoxyribonucleoside triphosphate
biosynthesis in T4-phage infected bacteria. They suggest
that it behaves as an organized complex, efficiently
channeling DNA precursors to the replication apparatus.
Previous work has suggested that about 10 enzyme
activities remain associated through several fractionation
steps. This multi-enzyme...
Rates of germination and emergence of corn were measured as
influenced by soil physical parameters using blotter paper and a sandy
loam soil as growth media. The corn seeds used were a hybrid of
Funk's (DJ7xLH93).
Experimental conditions were soil temperature of 20°C, 25°C,
30°C, and 35°C, soil water potential...
The nature of inheritance and possible associations for traits
influencing earliness and grain yield were investigated using a four
parent diallel of winter and spring wheat cultivars.
More genetic variability was observed for the traits measured in
segregating populations resulting from crosses between winter and spring
type wheats in contrast...
Bacteriophage T4 gene 42 encodes dCMP hydroxymethylase, an
enzyme unique to the deoxyribonucleotide metabolism of T-even
bacteriophages. To study biochemical and biophysical properties of
the enzyme, as well as the interaction of dCMP hydroxymethylase with
other DNA precursor biosynthetic enzymes in vitro, availability of large
amounts of the enzyme is...
