Answer:
Some forms of chromatin modification can be passed on to future generation of cells
Acetylation of histone tails in chromatin allows access to DNA for transcription
DNA is not transcribed when packaged tightly in a condensed form
methylation of histone tails can promote condensation of the chromatin
Explanation:
chromatin modifications that can be passed on includes epigenetic modifications that are heritable changes made to the chromatin structure that does not involve the DNA sequences. Some epigenetic modifications include DNA methylation and Histone modifications. examples of histone modification include acetylation, methylation, phosphorylation, ubiquintylation etc. All these function either in allowing the DNA become more accessible to transcritional factors or vice versa. for exmple, histone tail acetylation encourages unwounding of nucleosomes allowing transcriptional factors to have access to the DNa while histone tails methylation further tightens the nucleosomes promoting condensation of the chromatin.
<span>Meiosis helps prevent mutations from occuring over and over again.
In Meiosis process, the number of chromosomes during reproduction was caused in half.
During this process, the chromosomes that could potentiall caused mutation could be tossed out and therefore reduce its chance from happening</span>
Answer:
Humans exposed to high doses of chlorine can develop acute lung injury characterized by pulmonary edema, bilateral infiltrates on chest X-ray, hypoxemia, and respiratory failure.
Rem sleep ends when there is an increase in the level of serotonin and norepinephrine secreted.<span />
Monosaccharide molecules include, for example, glucose, galactose, and fructose.
- Carbohydrates are biomolecules whose building blocks are monosaccharides linked by glycosidic bonds.
- For example, lactose is a disaccharide consisting of one molecule of glucose and one molecule of galactose.
- Complex carbohydrates (e.g., starch) are in turn composed of linear/branched chains of monosaccharides.
In conclusion, monosaccharide molecules include, for example, glucose, galactose, and fructose.
