A forensic scientist wants to compare the DNA of several suspects for a crime. Which technique could be used to produce bands of DNA fragments for this comparison

The correct answer is - Gel electrophoresis.

Explanation:

Gel electrophoresis is a technique that is used in forensic science to compare the DNA of the crime suspects by creating or separating DNA fragments or bands on the basis of size.

In this method, DNA samples placed in the indentations at one terminal side of a gel, and an electric current is passed through the gel. DNA fragments are a move toward the positive charge as it is a negative charge.

The correct answer is - Gel electrophoresis.

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
