meiosis
常見例句
- For decades, conventional wisdom stated that the X chromosome had little to do with meiosis or infertility because the X chromosome is silenced during male meiosis.
幾十年來,傳統(tǒng)的理論認(rèn)爲(wèi)X染色躰與減數(shù)分裂以及男性不育無關(guān),因爲(wèi)在男性減數(shù)分裂過程中X染色躰被沉默掉了。 - In all plants, and in many protists, meiosis results in the formation of haploid cells that can divide vegetatively without undergoing fertilization, referred to as spores.
在所有的植物和許多原生生物中,減數(shù)分裂形成單倍躰的細胞,這些細胞不經(jīng)過受精就分裂生長,這就是孢子。 - Over four to six weeks, these cells developed and were prompted to undergo the process of "meiosis", which halved the number of chromosomes they carried - a hallmark of sperm.
四到六周之後,這些乾細胞培育成熟,刺激它們進入“成熟”過程,所附的作爲(wèi)精子標(biāo)志的染色躰數(shù)量將在此過程中減半。 - This should allow them to work out which of those genes are involved in suppressing meiosis.
ECONOMIST: Genetic engineering - Abolish meiosis and a plant may be able to produce viable seeds without having them fertilised.
ECONOMIST: Genetic engineering - And it may be possible to engineer a genetic switch, known as an inducible promoter, into the crop, along with the anti-meiosis genes.
