Contaminated soil can be rehabilitated by physical remediation methods, like aeration. What is another way soil can be treated t
Ivanshal [37]

Answer:

C) Flush out the contaminants with an excessive amount of water.

Explanation:

Water is universal solvent. It dissolve many solutes inside it. Soil is contaminated with number of chemicals which is used by farmers for the controlling of pathogens. These chemicals remains on the soil for very long time. These chemicals are removed from the soil by applying high amount of water which flush out the chemicals from the soil.

In fruit flies, gray bodies (G) are dominant over black bodies (g), and red eyes (R) are dominant over orange eyes (r). Each ind
Sindrei [870]

Answer:

The predicted genotype of the offspring is GgRr.

Explanation:

The gray body is dominant over black body. The genotype of gray body is GG and the genotype of black body is gg. Red eyes are dominant over orange eyes. The genotype for red eye is RR whereas the genotype of orange eye is rr.

GGRR is crossed with ggrr, the offspring produced by this cross is GgRr with gray body and red eyes.

GGRR  ×   ggrr

 GgRr.

Indicate whether each of the following statements is true of depurination (DP), deamination (DA), or pyrimidine dimer formation
solniwko [45]

Answer:

- This process is caused by spontaneous hydrolysis of a glycosidic bond: depurination and deamination

- This process is induced by ultraviolet light:  pyrimidine dimer formation

- This can happen to guanine but not to cytosine: depurination

- This can happen to thymine but not to adenine:  pyrimidine dimer formation

- This can happen to thymine but not to cytosine: none

- Repair involves a DNA glycosylase: deamination

- Repair involves an endonuclease: depurination, deamination and  pyrimidine dimer formation

- Repair involves DNA ligase: depurination, deamination and  pyrimidine dimer formation

-  Repair depends on the existence of separate copies of the genetic information in the two strands of the double helix: depurination, deamination and  pyrimidine dimer formation

- Repair depends on cleavage of both strands of the double helix: none

Explanation:

Depurination is the loss of purine bases (either adenine or guanine), while deamination refers to the removal of an amino group. During depurination, a β-N-glycosidic bond is cleaved by hydrolysis and a nucleic base is released (either adenine or guanine). All DNA bases may undergo deamination, except thymine (since thymine does not have an amino group). The ultraviolet (UV) radiation can cause thymine or cytosine to form dimers (e.g., pyrimidine dimers), being thymine dimers the most common lesion when DNA is exposed to UV light. Pyrimidine dimers may be repaired by different excision mechanisms, e.g., nucleotide excision repair, where the recognition of the DNA damage leads to the removal of the DNA fragment containing the lesion. DNA glycosylases are enzymes involved in the mechanism of base excision, these enzymes recognize and remove damaged bases by hydrolysis of the glycosidic bond, producing an abasic (apurinic and apyrimidinic) site. A DNA ligase enzyme covalently joins two DNA molecules by forming a phosphodiester bond, which is required during these processes.
