Answer:
vaccines were designed by using new technologies (i.e., RNA-based vaccines and adenovirus-based vaccines)
Explanation:
RNA-based vaccines are vaccines based on the delivery of specific messenger RNA (mRNA) sequences that are capable of encoding only one viral protein, thereby preventing the complete viral cycle/replication. Subsequently, this protein is recognized by the immune system that generates memory immunity by synthesizing specific antibodies against this protein (in this case, the spike S protein). On the other hand, adenovirus-based vaccines are vaccines designed by inserting a transgene cassette into an adenovirus which is used as vector to produce one specific viral protein inside the host. Like mRNA vaccines, this antigenic viral protein is then recognized by the immune system in order to produce antibodies against a defined protein epitope, thereby producing memory immunity.
The answer is "<span>Half of the strand is already correct and does not need correction".
Semiconservative replication would create two duplicates that each contained one of the first strands and one new strand. Moderate replication would leave the two unique format DNA strands together in a twofold helix and would create a duplicate made out of two new strands containing the greater part of the new DNA base sets.

Wave Frequency:
<u><em>Wave frequency is the number of waves that pass a fixed point in a given amount of time.</em></u>
How do you find the frequency of a wave?
<u><em>To calculate the frequency of a wave, divide the velocity of the wave by the wavelength. Write your answer in Hertz, or Hz, which is the unit for frequency. If you need to calculate the frequency from the time it takes to complete a wave cycle, or T, the frequency will be the inverse of the time, or 1 divided by T.</em></u>
