Answer:
lytic, because of the quick onset of symptoms after infection
Explanation:
As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.
The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.

leave the nucleus, goe to the cytoplasm,bind to a ribosome to be read
Different versions of a gene are called alleles. Alleles are described as either dominant or recessive depending on their associated traits.
Answer:
Lactase
Explanation:
Lactaid is a medication that contains the milk protein digesting enzyme Lactase. It is an enzyme supplement for those people who have trouble in digesting milk and other dairy products. Such condition occurs in Crohn's disease and termed as lactose intolerance. Lactase specifically acts on the lactose containing substrates and digests them by enzymatic activity. So people with lactose intolerance can be able to take dairy products with the help of Lactaid.
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from errors during DNA replication or other types of damage to DNA, which then may undergo error-prone repair, or cause an error during other forms of repair, or else may cause an error during replication. Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics of an organism.
