Answer:
DNA has a double- helix structure which means it has two strands. The DNA strands are made from sugar (Deoxyribonucleic), phosphates and nitrogenous bases. There are 4 nitrogenous bases, 2 purine and 2 pyrimidine. The 2 purine bases are Adenine and Guanine. The pyrimidine bases are Thymine and Cytosine. DNA gives our genes.
RNA is a single strand unlike DNA. The strands are made from sugar (ribonucleic), phosphate and the nitrogenous bases. There are 4 nitrogenous bases 2 purine and 2 pyrimidine. The 2 purine bases are Adenine and Guanine. However, the 2 pyrimidine bases are Uracil and Cytosine. The function of RNA is to contribute to releasing proteins based on our rRNA and tRNA and mRNA. This process is known as RNA and transcription.

Administer varicella vaccine to the health 6-year old child (who does not have evidence of immunity to varicella) was exposed to a confirmed case of varicella 2 days ago.
Explanation:
It is seen that if a child receives varicella vaccine between 3 to 5 days of exposure, he is safe as disease will not appear in him and would be saved for future infections.
Varicella vaccine is given for prevention against small pox. It is expected once immunised with varicella body will produce antibodies for a span of twenty years or more.
