Answer:
The electron microscope
Explanation:
<u>The microscope that would be best suited to study the inner structure of the chloroplast would be the electron microscope.</u>
<em>The electron microscope has a high magnifying property due to the fact that it uses a beam of accelerated electrons as a source of illumination, unlike the light microscope that uses visible light. While the light microscope might be enough to see the inner portion and the organelles of the cell, the tiny nature of the inner structure of the chloroplast means that the light microscope will not be able to view the details. A more powerful microscope like the electron microscope would be required.</em>
Answer:
False
Explanation:
The histones that are more positively charged, tight hardly to negatively charged DNA. So, enzymes, such as acetyltransferases, that reduce the positive charge of histones promote transcription.
Chromatin structure and its modifications can change the package of the DNA and consequently, alter the gene expression. The most common modifications of the chromatin are covalent modifications such as acetylation/deacetylation (by acetyltransferases and eacetylases), methylation (by methyltransferases), and phosphorylation (by kinases). This is the way of gene expression regulation.
The effects of modifications are different, for example methylation promotes condensation of the chromatin and as a consequence, prevents binding of transcription factors to the DNA (transcription is repressed).
Acetylation loosens the association between nucleosomes and DNA (because it neutralizes the positive charge of histones) and consequently promotes transcription. Deacetylation is a process opposite to acetylation.
Answer:
Where the cell divides
Explanation:
I think the equator, or equatorial plate, is the midline of the cell where duplicated chromosomes position during mitosis.
