Sedaia [141]

After cloning the Glo gene in the puc18 plasmid of E.Cori, the next step would be to culture the clone.  While amplifying DNA requires Polymerase Chain Reaction cycles, amplifying proteins requires the metabolic activity of <span>organisms to utilize central dogma process and ribosome activity to produce proteins.  Culturing produces many clones that synthesize the proteins in significant amounts. </span>

What might be some challenges of working in a forensic biology lab?
OleMash [197]

Answer/Explanation:

  • You would have to be very careful of cross-contamination. That means you would have to work very carefully and precisely with protective clothing, ensuring that none of your DNA (from skin or hair or even trace) gets into the sample you are working with
  • You would have to be very careful to check and record samples properly to ensure nothing got mixed up or mislabeled and this could be disastrous for criminal cases
  • All the material is very precious and sometimes only one sample exists, so you have to avoid making any mistakes. Experiments can't always be repeated.

Restriction endonucleases are especially useful if they generate sticky ends. What makes an end sticky?
Mazyrski [523]

The question is incomplete as it does not have the options which are:

A) single-stranded complementary tails

B) blunt ends

C) poly-A sequences

D) 5' cap

E) interference

Answer:

A) single stranded complementary tails

Explanation:

Restriction endonuclease is the enzyme which cuts the DNA sequence in the internal sequence.

The endonuclease enzyme can cut the DNA sequence in a way that it can form the cuts with the single-stranded overhangs called sticky ends and without overhangs called blunt ends.

The sticky ends are produced when the enzyme makes cut at the single strand and then makes the cut at between the same base at the nitrogenous base. This type of asymmetrical cut forms the single-stranded overhangs which can form the complementary base pairs easily.

Thus, Option-A is correct.

25+ POINTS!<br><br> Quick question, how do scientists use genetic information? Why is it useful?
LenaWriter [7]

Answer:

The new genetic information is useful to public health scientists because it allows them to test for relationships between diseases and genetics.  The most common way scientists collect genetic information on a DNA sample is to interrogate a specific point in the genome using a technique we call “genotyping.”
