DNA replication
`The process of DNA and RNA transcription involves various steps, including the replication of DNA, transcription of DNA to RNA and the translation of RNA to proteins. These processes take place in the body and are responsible not only during the development of an individual but also when they are mature. The process is complex and takes place every minute hence making any error in the process to have a significant impact on the result. Errors in this process can occur during the DNA replication step as well as the translation of RNA to proteins. During DNA replication, one of the errors that can happen is the insertion or deletion of letters that make up the genetic code.
Such an error may cause the resulting protein to be short or long. This error can have a dramatic effect on the structure of protein formed, and the deletion or insertion of a single letter can lead to frameshift mutation hence affecting the resulting trait. Transcription is the stage where the DNA is transcribed to mRNA that contains the information necessary for protein synthesis. Transcription occurs in two steps, including the formation of a pre-messenger and RNA splicing. Alternative splicing occurs in the last step, and errors could occur during the stage. While splicing is crucial since it helps to code for different types of proteins, the abnormal process of splicing can lead to diseases such as cancer.
Flu is one of the illnesses that are more common and dangerous for young children. Many children have been hospitalized and even died due to influenza hence making it essential for them to be vaccinated. The provision of flu vaccines is effective in controlling influenza, and these should be given on a seasonal basis. Since flu is transmitted from one person to the other through a cough or sneezing, it would be necessary for school going children to obtain a vaccine. Children who come in contact with others while playing will infect them hence affecting their education due to missed school days. The vaccine should also be administered to hospital workers whose nature of work will involve coming into contact with their patients.
