Меси Птерис Олонце олат, как будто заклинание произнёс.

А между прочим, это невзрачно растение из Новой Зеландии стало рекордсменом по размеру генома среди всех известных живых существ. Геном этого папоротника состоит из 160 млрд пар оснований.

Между прочим, ваш геном, да и мой тоже, состоят всего лишь из 3 млрд пар. Но не стоит чувствовать себя неполноценными. Давно известно, что сложность организма не зависит от размера его ДНК.

Этот рекорд по размеру генома принадлежал Пие японскому со 149 млрд пар оснований, а среди животных — рыбе мраморного протоптера со 130 млрд пар. Теперь же папоротник взял вверх.

Здесь важно, что учёные не секвенирования по размеру и по составу содержимого ядра клетки. Поэтому мы до конца не знаем, что привело к такому рекорду.
