3. mRNA: UAU-CCG-CAU, amino acids: tyrosine(tyr)-proline(pro)-histidine(his)

Explanation:

For DNA, the complementary bases are T=A and C=G. This means every time you see one of these letters, the corresponding letter goes with it. For mRNA, the bases are T=A, A=U, C=G. It is the same except now, there should be no "T" in the mRNA sequence. With amino acids, you would first code for the mRNA sequence, every three letters being the amino acid sequence. To find the amino acid, you would look at a codon chart unless your teacher wants you to memorize them.  The first three letters of the amino acid are the abbreviation.

Explanation:

Now that we have studied the various types of vaccines, consider the current resurgence of diseases like the measles. How can we convince the general public and possibly even ourselves, that immunization is a necessary preventative measure for diseases that have serious complications? Is there a different schedule that we should consider? Are some forms of vaccines safer than others? Should we spread out the inoculation schedule to prevent confusion of a young person?

Answers

Answer:

Immunization is one of the most effective processes of preventing or treating dangerous disease. It should be told and advertise to the general public about the facts and importance of vaccination. Doctors and government should explain the reports and ratio that the people who are taking the vaccination in the proper dose and the right amount of vaccination are about 9 timeless likely to have to the other people. It is essential to get a proper dose and proper amount to avoid the development of resistance.

There are several forms of vaccine and they have a different schedule from each other. Every vaccine is safe but one needs to know the cycles, dose and amount of the vaccine. Yes, we should spread out the inoculation schedule to prevent confusion of a young person.

Challenge question! Imagine the following situation. You receive a viral vector coronavirus vaccine that uses a specific adenovirus and your immune system mounts a strong immune response. At the same time, your friend receives an RNA coronavirus vaccine and also has a strong immune response. One year later a new coronavirus variant emerges and neither of the original vaccines protect people from this new variant.

A new viral vector vaccine is developed to the variant using the same adenovirus as before. In clinical trials, it is found that the new vaccine protects people that originally received the RNA coronavirus vaccine that your friend had but does not protect people that originally received the viral vector coronavirus vaccine that you had.

Question: Can you think of an explanation for why the new vaccine didn’t protect you, but did protect your friend?

Answers

Answer:

she took more care of her self and her immune system its more advance rather than the other person!

Explanation:

Due to being more careful meaningly taking care of not catching it, but also just cause you had it doesnt mean you're going to be carless "free" because you got the vaccine.

your friend could've been protected even though she had the vaccine she was not carless unlike the other person she thought about her actions.

Answer:

Explanation:

Introducing a new species to a new ecosystem often leads to a disaster because of the absence of bioagent for that species. Bioagent are those organisms which has the ability to control other organisms by feeding on them. A new species does not make problem in its old or original ecosystem due to the presence of controlling agents but in the new ecosystem there is no bioagent that can stop its growth so that's why sometimes the introduction of new species leads to a disaster.
