Answer:
I'm pretty sure it's A. yes they do
Answer: Option B) determine the sequence of amino acids in a protein
Explanation:
The messenger RNA (mRNA) molecule carries a seqence of bases that is complimentary to the template strand of DNA.
Hence, instead of thymine, uracil nucleotides exists in the mRNA molecule; while the mRNA is transcribed to the corresponding amino acids.
For instance: a template strand of ACC CGG is transcibed as UGG GCC on mRNA, and translated to an amino acid sequence of Tryptophan and Alanine.
The correct answer is - Since 2000, more people are living with HIV, but fewer people are dying from AIDS.
Since the year 2000, the number of people that are living with HIV has been steadily increasing, though it has to be noted that the rise has been gradually slowing down. On the other hand, despite having more living with HIV, the deaths by AIDS have reduced gradually.
The main reason for the increase of people living with HIV is simply that there's more and more people in the world that can contact physically much more easily, so the disease can be transferred much more easily over larger distances. On the other hand, less and less people are dying from AIDS, and the reason for that is the discovering of the disease in its early stage, as well as the development of the medicine and keeping a certain routine in the lifestyle that is healthy.
Option (A) identifies them correctly.
During Meosis 2 daughter cells are formed from a single cell and the chromosomes are equally divided in both the cells.
So, Cell P had 60 chromosome, after miosis 2 daughter cells of each having 30 chromosomes formed, and again after Miosis of from each of those 2 those daughter cells, 2 more daughter cells are formed with equal naumber of chtomosome which equals 15.
