Under each DNA sequence write the complimentary mRNA base sequence that each of these gene fragments would produce. Remember tha
s344n2d4d5 [400]

Answer:

The correct answer would be -

Thymine to adenine

Cytosine to guanine

guanine to cytosine

<u>Adenine</u>, and <u>"U" uracil</u> respectively.

Explanation:

mRNA is a sequence of complementary base sequences encoded from a gene or DNA segment which is used to produce the protein by the process called translation.

From converting a sequence from DNA to its complementary mRNA sequence, the rules of complementary base pairing will be applied: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A) and Thymine is replaced by adenine.

Calculate the molarity of a solution containing 9.25 mol H2SO4 in 2.75 L of solution.
Akimi4 [234]

Answer:

THE MOLARITY OF THE SOLUTION IS 3.36 MOLE/L

Explanation:

First we must understand what molarity is.

Molarity is the number of mole per unit volume of solution. In this question, 9.25 mole of H2SO4 was given in 2.75 L of solution.

Molarity is written in mole per dm3 or L.

So we can calculate the molarity:

9.25  ole of H2SO4 = 2.75 L of solution

The number of mole in 1 L of solution will be:

= 9.25 mole / 2.75 L

= 3.3636 mole/ L

In conclusion, the molarity of the solution is approximately 3.36 mole/L
