qwelly [4]

In eukaryotic cells, the DNA that codes for the cell's proteins is stored in a membrane-bounded organelle called the nucleus.

<h3>What is the nucleus?</h3>

The cell nucleus is an organelle delimited by a membrane where the cellular genetic material organized in DNA molecules together with proteins such as histones is stored. Its function is to keep this genetic material protected and control the expression of DNA, as in the transcription of proteins.

Therefore, we can confirm that In eukaryotic cells, the DNA that codes for the cell's proteins is stored in a membrane-bounded organelle called the nucleus.

What advantage do invasive species of plants have over native species?.
alexandr402 [8]
They are better competitors because they emerge earlier in the spring, grow rapidly, and are impacted by few, if any, natural predators. When invasive plants are allowed to grow unchecked, many native plants and the wildlife species that rely upon them suffer.

Homologous chromosomes are similar in all of these characteristics except:
Gnesinka [82]

Answer:

Except alleles

Explanation:

Alleles are different versions of the same gene and that's because they have different DNA, even though it is slightly different it can make a lot of changes so that's why they have different alleles.

Allele is actually the variant form of some genes.

The best<u> example </u>for alleles we can find in the gene for blossom color in some species of flowers or plants. Only one single gene is controlling the color and we can see sometimes different versions of it. Those different versions are called Alleles.

<h2>Nuclear Envelope</h2>

Explanation:

  • <em>The endomembrane system</em> includes the nuclear envelope, the <em>endoplasmic reticulum, Golgi mechanical assembly, lysosomes, vesicles, just as the plasma layer</em>
  • These cell parts cooperate to <em>alter, bundle, tag, and transport layer lipids and proteins </em>
  • The nuclear envelope is a double membrane, implying that there are <em>two lipid bilayers</em>
  • The nuclear lamina, a netlike cluster of <em>protein filaments, associates the layers of the nuclear envelope</em>
