Proto-oncogenes signal cells to grow and differentiate. However, they can become oncogenes due to mutations which result in the uncontrollable division of the cells, i.e. cancer. One way is a point mutation in a proto-oncogene. The consequence is changed protein product. Another way is gene amplification of DNA segment containing a proto-oncogene. As the result, the encoded protein is overexpressed. The third way is translocation. As the result of translocation, proto-oncogene can be controlled by the different promoter and expressed inappropriately.
The answer is false.
Distress is a state in which a person shows maladaptive behaviour. This happens because an individual can’t adapt to stressors and the stress they produce. Thus, people under constant distress are often likely to become sick.

Eustress is the opposite of distress. It is a positive stress that motivates people.</span>
Answer;
-5-carbon sugar
Explanation;
-The basic repeating unit of nucleic acids are known as nucleotides. There are two types of nucleic acids, namely RNA and DNA.
-A nucleotide consists of three distinct chemical groups, a 5-carbon sugar (ribose or deoxyribose), a nitrogen-rich base - (cytosine (C), guanine (G), adenine (A), thymine (T) in DNA or uracil (U) instead of T (in RNA), and phosphate.
A hypothesis is a vital part of not only the scientific method but in experimenting, whether or not you are familiar with the method. A hypothesis is important, because by stating your perspective and percieving on the topic you are able to build on that, despite how much it may be wrong or how much it may be right. It's the first step to forming a final conclusion. With a hypothesis you can fully build and construct the final results and conclusion to any experiment or topic you are focusing on.
