The majority of RNA is spermatozoa from the epididymis and ductus deferens of mice was found to be 28 s and 18 s RNA. This RNA was also seen in human ejaculated spermatozoa. Our evidence indicates that little or none of the 28 s and 18 s RNA is transcribed in the maturing mouse spermatozoa and that the majority is synthesized in the primary spermatocyte. This RNA may be necessary to maintain post-meiotic translation during spermatogenesis.
在小鼠附睾和输精管的大多数精子中发现的RNA主要是28 s和18 s RNA。在人类射出的精子中也观察到了这种RNA。我们的证据表明，28 s和18 s RNA在成熟的小鼠精子中很少转录或不转录，并且大部分是在初级精母细胞中合成的。这种RNA可能是精子发生过程中维持减数分裂后翻译所必需的。
