Answer:
The correct answer will be option-Crossover region
Explanation:
Recombination is a complex process which leads to the exchange of the genetic material between sister chromatids.
The recombination process is mediated by the recombinase enzyme which recognize the specific sites and allows the formation of the protein-DNA complex called synaptic complex.
The synaptic complex contains the short asymmetric sequence called the crossover region, which represents the rejoining and the DNA cleavage site.
Since crossover region represents the recognition sequence which is flanked is known as the crossover region.
Thus, the crossover region is the correct answer.
Answer:
D) epithelial tissue
Explanation:
The exchange surfaces of the organisms are the site for an exchange of substances or gases. These surfaces mostly lie within the body and protect the exchange tissues. The exchange surfaces of multicellular organisms are lined with epithelial tissues. These tissues have tightly packed cells with little or no intercellular spaces. The epithelial tissues serve to protect the exchange surfaces. Sometimes, these epithelial linings are modified to perform an additional function. The exchange surfaces are finely branched or folded to have a very large area. The digestive, respiratory, and excretory systems all have such exchange surfaces.
Answer:
If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children
Explanation:
Even tho the cause of lung cancer is not very clear, a genetic predisposition is of a great influence, his smoking and therefore causing a lung cancer is not appliable to his children because of no connection, but in the sense of having a mutation which makes you predisposable to the cancer with or without the smoking, can lead to a high risk of gene inheritance and therefore inheriting the mutation with a high risk of getting lung cancer excluding the smoking.
Answer:
For example, addition of an orange chromic acid reagent to some compounds causes the chromium reagent to change to a blue-green color (Figure 6.37a). This is considered a "positive" test result, and in this case indicates the presence of a functional group that can be oxidized (alcohol or aldehyde).
