Question

Как отсутствие ядра влияет на свойства клетки?

Answer 1

Вот:
у прокариот ДНК замкнута в кольцо; 
нет линейных хромосом; 
митоз и мейоз отсутствует; 
отсутствуют также гаметы (репродуктивные клетки, имеющие гаплоидный (одинарный) набор хромосом), соответственно нет полового размножения; 
способ питания - адсорбция через клеточную мембрану; 
нет пищеварительных вакуолей; 
органеллы с меньшем количестве, неограниченны мембраной; 
сама клетка гораздо меньшего размера 

прокариоты размножаются в основном простым делением пополам, в то время как эукариоты делятся при помощи митоза, мейоза или сочетанием этих двух способов. как следствие, размножение доядерных происходит гораздо быстрее

How the Absence of a Nucleus Affects Cell Properties

The absence of a nucleus in a cell can significantly impact its properties and functions. Here's a detailed look at how this absence influences the cell:

Loss of Genetic Material: - The absence of a nucleus means that the cell lacks a defined nucleus-bound genetic material, such as DNA and RNA. This loss of genetic material can have several implications for the cell's functioning and capabilities.

Limited Protein Synthesis: - Without a nucleus, the cell's ability to synthesize proteins may be limited. This is because the nucleus is the site for transcription and contains the necessary machinery for this process. As a result, the absence of a nucleus can impact the cell's protein synthesis capabilities.

Impact on Cell Division: - The absence of a nucleus can affect the cell's ability to undergo typical eukaryotic cell division processes, such as mitosis and meiosis. These processes are crucial for growth, repair, and reproduction in multicellular organisms.

Altered Cellular Functions: - The absence of a nucleus can lead to altered cellular functions, as many essential cellular processes are regulated by the genetic material housed within the nucleus. This can impact the cell's ability to carry out various functions effectively.

Conclusion: In summary, the absence of a nucleus in a cell can have far-reaching effects on its properties and functions, including the loss of genetic material, limited protein synthesis, impact on cell division, and altered cellular functions.
