If you are administering a drug with a dosing rate of 50 mg/kg to a patient with a mass of 50 kg, how many mg of drug do you need to deliver to the patient?O 25 mg
O 2,500 mg
O 250 mg
O 2.5 mg
O 50 mg

Answers

0.330 and the 3 is what you rounded up

Final answer:

To calculate the dosage of a drug given in mg/kg for a person, multiply the dosing rate by the person's mass. In this case, the dosing rate is 50 mg/kg and the mass of the person is 50 kg, yielding a total dosage of 2,500 mg.

Explanation:

When administering a drug with a dosing rate that is given in mg/kg, you need to multiply the dosing rate by the patient's mass to determine the proper dosage. In this case, we use the formula:

Dose = Dosing rate × mass

Substituting the given values into the formula:

Dose = 50 mg/kg × 50 kg, which equals to 2,500 mg.

Therefore, you need to administer 2,500 mg of the drug to the patient.

A DNA strand has the codon AAT. According to the chart, the corresponding messenger RNA codes for which amino acid?

Answers

Answer:

Asparagine (symbol Asn)

Explanation:

In a gene, groups of three nucleotides (such as AAT) form codons that are read during translation, for the synthesis of proteins. The way codons are read can be found in a genetic code (attached here).

Before that, the DNA seuqences are transcripted to RNA sequences in order to be read and translated in the ribosome.

AAT (DNA sequence) will be transformed to AAU during the transcription of DNA. This is because during the transciption process all thymines (T) are replaced by Uracils (U).

In the genetic code you can see that AAU is read as Asparagine.

Because Thymine is "replaced" with Uracil, the corresponding RNA Code for AAT would be UUA.
