It is customary in genetics to use strand for chromatid. It has therefore been used in that sense in some books, where it has also been used for one double-chain (that is, duplex) DNA molecule.
one strand of DNA in a chromosome is "immortal'; that is, it will serve as an unchanged template as it is passed on from generation to generation [Link].
