### Subject: Biology

Transcribe the following DNA strand into mRNA, then translate the mRNA into an amino acid sequence: TACTTTTCG

To transcribe the DNA strand into mRNA, remember that adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). However, in RNA, thymine is replaced by uracil (U) as the base complementary to adenine. Therefore, the mRNA sequence will be: AUGAAAAGC. To translate the mRNA sequence into an amino acid sequence, refer to the codon chart and match each codon (three consecutive nucleotides) with its appropriate amino acid. The amino acid sequence turns out to be: Met-Lys-Ser.

### Subject: Algebra

John bought 5 pints of ice cream and a birthday cake the grocery store for a total of $45. If the price of the birthday cake was $25, what is the price of one pint of ice cream?

First, we will translate the scenario into an algebraic equation, then solve the equation for the price of a pint of ice cream. John bought 5 pints of ice cream. We can use x to represent price of one pint of ice cream. The price of 5 pints of ice cream can then be represented by 5x. John spent a total of $45, which is the sum of $25 from the birthday cake and $5x from the ice cream. Thus, we can write and solve the algebraic equation: 25+5x=45 5x=20 x=4 This means that each pint of ice cream costs $4.
