Answer:
the relationships are probably mutual or parasitic
Explanation:
The argument of most scientists when it comes to commensalism is that the likelihood of a relationship between two different organisms, where one of the organisms to be completely unaffected is low. They propose that their relationship, although not obvious, is more likely to be mutualistic or parasitic at best.
Answer:
In the first step of meiosis I, the chromosomes/genetic material of the cell condenses into a visible form, into a form called heterochromatin. The nucleolus also disappears.
In the second step, a process called synapsis occurs. This is when homologous chromosomes align themselves, gene by gene.
In the third step, crossing over occurs. Segments of corresponding DNA are cut and exchanged between non-sister chromatids of the formed tetrads.
In the fourth step, the nucleus fragments, the nuclear envelope fragments, the two centrosomes (if we're talking about an animal cell) separate from each other as their asters and mitotic spindles (mostly microtubules (kinetochore and non-kinetochore) lengthen. The microtubules extending from the centrosomes can now connect to chromosomes.
Explanation:
1. they are convenient to use 2. it helps the international tade 3. it eases the exchange of material
Answer:
A general decrease in transcriptional activation
Explanation:
When acetyl groups are added to histone proteins by acetyltransferase enzymes, the 30-nm chromatin fiber will not be formed because the proteins are prevented from doing so. This further destabilizes the chromatin structure and allows the occurrence of transcription. However, raising the cells to 40°C does not allow the acetyltransferase enzyme to function and hence the acetyl group will be hindered from being added to the histone protein which is the main target of the enzymes. Thus, transcription activation will be blocked because the chromatin and nucleosomes would remain stabilized.
Dab most likely inhibits phosphorolysis of glycogen reaction.
<h3>What is
phosphorolysis?</h3>
- Inorganic phosphate acts as the attacking group during phosphorolysis, which is the cleavage of a molecule.
- It's comparable to hydrolysis.
- A reversible process akin to hydrolysis where phosphoric acid behaves like water and produces phosphate as a byproduct.
- It's comparable to hydrolysis.
- Glycogen phosphorylase, which catalyzes the assault of inorganic phosphate on the terminal glycosyl residue at the nonreducing end of a glycogen molecule, is an example of this.
- The difference is that while reactions involving hydrolysis use water to split larger molecules into smaller ones, reactions involving phosphorolysis use phosphate to achieve the same result.
- The primary enzyme in utilizing the glycogen reserves in the muscle and liver is known as glycogen phosphorylase.
- It catalyzes the sequential phosphorolysis of glycogen to liberate glucose-1-phosphate.
