Answer:

Primers should be:

3 'ACGTATGTCGCTTAGT 5'

5 'ACGTTCCAGTCAATGA 3'

Explanation:

DNA replication occurs with the need for the presence of primers that are a small sequence of nitrogenous bases that will allow the initiation of replication.

Primers are extremely important in PCR and are represented as small pieces of single-stranded DNA that specify the region of DNA that should be replicated during PCR. These primers attach to the single strand of DNA by pairing the nitrogenous bases allowing the DNA polymerase to recognize where replication begins.

Regarding the question above, the primers should be:

3 'ACGTATGTCGCTTAGT 5'

5 'ACGTTCCAGTCAATGA 3'

Adult tickets for the school musical sold for $3.50 and student tickets sold for $2.50. On a given night, 321 tickets were sold
nalin [4]

Answer:

total amount spent on student ticket = 186($2.5)=$465.00,

Total amount spent on adult tickets = 135($3.5)=$472.50

Explanation:

cost total = student ticket price (x) + adult ticket price (321 - x)

$937.50 = (2.5)(x) + (3.5)(321 - x)

$937.50 = 2.5x + 1123.5 - 3.5x

x = 186, therefore 186 student tickets sold,  

(321-x) = 321-186 = 135, therefore 135 adult tickets were sold.

total amount spent on student ticket = 186($2.5)=$465.00,

Total amount spent on adult tickets = 135($3.5)=$472.50

So the total amount spent on tickets was  

$472.50 + $465.00 = $937.50
