Answer:
Hypermethylation of___ promoters will lead to reduced expression of the correspondent genes. Some genes such as Cell Cycle stop genes _and__DNA repair genes_need to be expressed. When they__are not expressed_, this can lead to cancer.
Explanation:
Oncogenes are genes that may trigger cancer, where they are generally overexpressed (i.e., expressed at high levels). Although there are well-documented exceptions to this rule, DNA methylation generally represses gene expression by preventing the binding of transcription factors to promoters. It is known that the hypermethylation of tumor suppressor genes including, for example, cell cycle stop genes and DNA repair genes, may lead to cancer. Similarly, hypomethylation of oncogenes such as, for example, Cyclin D1 (a cyclin-dependent kinase involved in cell cycle progression), may also contribute to carcinogenesis.
The triplet of basis on the DNA and mRNA is known as a codon. It's a code for a specific amino acid.
Answer:
Explanation:
Let the frequency ,
Now the unit of frequency is hertz = s⁻¹ = T⁻¹ where T is time, tension T = kgm/s² = MLT⁻¹ and linear density m = kg/m = ML⁻¹.
So,
![T^{-1} = L^{x}[MLT^{-2} ]^{y}[ML^{-1} ]^{z}\\](https://tex.z-dn.net/?f=T%5E%7B-1%7D%20%20%3D%20L%5E%7Bx%7D%5BMLT%5E%7B-2%7D%20%5D%5E%7By%7D%5BML%5E%7B-1%7D%20%5D%5E%7Bz%7D%5C%5C)
collecting the like bases, we have
![T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ] \\L^{0} M^{0} T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ]](https://tex.z-dn.net/?f=T%5E%7B-1%7D%20%3D%20%5BL%5E%7Bx%20%2B%20y%20-z%7D%5D%5BM%5E%7By%20%2B%20z%7D%20%5D%5BT%5E%7B-2y%7D%20%5D%20%5C%5CL%5E%7B0%7D%20M%5E%7B0%7D%20T%5E%7B-1%7D%20%3D%20%5BL%5E%7Bx%20%2B%20y%20-z%7D%5D%5BM%5E%7By%20%2B%20z%7D%20%5D%5BT%5E%7B-2y%7D%20%5D)
Equating powers on both sides, we have
x + y - z = 0 (1)
y + z = 0 (2)
-2y = -1 (3)
From (3), y = 1/2
From (2), z = -y = -1/2
Substituting y and z into (1), we have
x + y - z = 0
x + 1/2 - (-1/2) = 0
x + 1/2 + 1/2 = 0
x + 1 = 0
x = -1
So,
Answer:
adaptation is what's happening, and the moths changed color to adapt to the new environment.
because of the smoke, the light colored moths were easily spotted and eaten. but they changed color over time to account for that, turning black to make them harder to spot and eat.
