Helical repeat of DNA in solution.

The helical repeat of DNA in solution has been measured directly by analyzing the gel electrophoretic patterns of pairs of covalently closed DNAs with length differences between 1 and 58 base pairs, out of a total length of about 4350 base pairs per DNA molecule. The method is based on the observation that for a covalently closed DNA of a fixed size of n base pairs (n of the order of several th...

Proposed conformation of oxytocin in solution.

A conformation of the neurohypophyseal hormone oxytocin in solution is proposed. The structure possesses, in addition to the beta-turn comprised of the sequence -L-tyrosyl-L-isoleucyl-L-glutaminyl-L-asparaginyl- in the ring component of the hormonal molecule, a second beta-turn involving the C-terminal oxytocin sequence, -L-cysteinyl-L-prolyl-L-leucylglycinamide. The resulting oxytocin structur...
