Absorbe la mayor parte de la radiación ultravioleta del sol (UV-B), reduciendo la cantidad que llega a la superficie de la Tierra. Dado que esta radiación provoca cáncer de piel y cataratas, la capa de ozono es esencial para la protección de la salud humana.
Si me he equivocado, pido disculpas. Además, lo he sacado de un traductor, por lo que puede sonar extraño.
You should use the same amount of beads for both chromosomes because they need to match in size.
I am assuming you are making a pair of homologous chromosomes out of pop beads, and they should have the same size because they code the same information, the only difference between them is that one comes from the mother and ther other from the father. (Homologous chromossomes have the same genes in the same loci).
The first law. Planets orbit is an ellipse with the Sun at one focus.
If you were able to look very closely at a portion of dna and find methylated histones, you would be looking at a region of inactive chromatin.
- Histone methylation is the process by which methyl groups are added to the histone protein amino acids, which create the nucleosomes around which the DNA double helix coils to form chromosomes.
- Histone methylation is the addition of one, two, or three methyl groups to certain amino acids within a histone protein. Histones are coiled around DNA in the cell nucleus.
- These findings collectively imply that DNA methylation can be either active—as a probable contributor to levels of gene expression variation—or passive—as a result of or a separate indicator of gene expression levels.
