How are embryonic stem cells different from other types of stem cells?

Biology
1 answer:
Oksi-84 [34.3K]3 years ago
5 0
These include each of the more than 220 cell types in the adult body. Pluripotency distinguishes embryonic stem cells from adult stem cells found in adults; while embryonic stem cells can generate all cell types in the body, adult stem cells are multipotent and can produce only a limited number of cell types.

The interaction between DNA and histone proteins (forming nucleosomes) plays a key role in the regulation of gene expression in
ladessa [460]

Answer:

A. The chromatin near cis-regulatory sequences will be more closed and there will be less transcription.

Explanation:

In the presence of histones, the cis-regulatory sequences of DNA like promoter, enhancers etc. are not exposed. The function of the histone acetyltransferases (HATS) is to cause chromosome decondensation i.e. removal of histones from the DNA so that transcription of the DNA could occur. Histone acetyltransferases (HATS) cause acetylation of lysine amino acid of the histone proteins. Acetyl group is negatively charged so the acetylation of histone proteins leads to the removal of their positive charge which ultimately leads to the decrease in the interaction between N terminal of histones and negatively charged phosphate group of the DNA molecule. As soon as histones are removed from the DNA where cis-regulatory sequences are located, the DNA becomes accessible for transcription.

But here a drug has been added which blocks the activity of histone acetyltransferases (HATS) in cancer cells. So it is quite evident that in these cells, histones will not get removed from the cis-regulatory sequences of DNA so the DNA will be more closer or tightly packed as a result of which  less transcription will occur.

Question 13 of 34
Gemiola [76]

Answer: A) Hydrogen Bond

Explanation:

A hydrogen bond occurs when a hydrogen (H) is covalently bound to a more electronegative atom or group forms an electrostatic attraction to another electronegative atom bearing a lone pair of electrons. This is possible due to the polarity of the H-electronegative atom bonds.
