Question 2
D) Carbohydrates
Answer:
1. RNA polymerase binds to the promoter.
2. DNA strands are unwound and separated
3. The complementary RNA nucleotides are added.
Take a look at the attached picture. First, the RNA polymerase must bind to the promoter region to initiate the whole process. DNA must be unwound by DNA helicase, then it will make the RNA transcript, which consists of adding the complementary RNA nucleotides to the DNA strand. Then the transcript leaves the nucleus and begins translation.
The second pair of ribs or the true ribs
Answer:
It is recommended to get a flu shot every year as the flu shot only provides protection against the flu for about 6 months. An individual's immune protection from the vaccination declines over time, so they need a new vaccine for optimal protection. In addition, flu viruses evolve and mutate very quickly. New flu vaccines are administered every year to address the rapidly adapting flu virus.
