chromatid

1.At anaphase the dicentric chromatid will form a bridge and the acentric a fragment, both of which can be scored.

在后期双着绿点染体将形，着绿点染体单体形片，此两者均可记录下来。

2.At this point esch chromosome consist of a pair of chromatids and the two associated chromosomes are termed a tetrad.

此时每条染体由对染单体构，这两条联合的染体称为四分体。

3.Diplotene In MEIOSIS, the stage in late PROPHASE I when the pairs of chromatids begin to separate from the tetrad formed by the association of homologous chromosomes.

双线期：在减数第次分裂的前期中的靠后的阶段。

4.Human Peripheral blood exposed with tritiated water at variousdoses for 54 hr was examined to observe the chromosome and chromatid abe-rrations at metaphases in the first mitosis of lymphocytes.

将人体外周血在不同剂量的氚水中培养54小时,观察到淋巴细胞第次有丝分裂中期的染体型及单体型畸变。
