Answer:

Suppression of Abl reduces the severity of abnormal axonal guidance in PTP mutants

Explanation:

Axon guidance is a neural development subfield relating to the mechanism by which neurons send out axons to meet their right targets.

ABL gene is a protooncogene that encodes a protein tyrosine kinase involved in a variety of cellular processes. PTPs are known to signal a number of cellular processes, including cell development, differentiation, mitotic cycle, and oncogenic transformation.

Suppression of Abl reduces the severity of abnormal axonal guidance in PTP mutants.

Can anyone tell me what the # of DNA fragments are?

Svetach [21]

Answer:

1. 3

2. 2

3. 3

4. 3

5. 3

6. 3

The total number of fragments is 17

Explanation:

What the image shows is 6 columns of DNA sequences. It looks like the annotations represents cut sites for restriction enzymes. Restriction enzymes cut at defined sequences. The cut site is represented by the horizontal line (see attached pic, red arrows).

That means any time there is a horizontal line, a new fragment is made. Remember that the DNA is double stranded, so the cuts made will produce what we call "overhangs" or "sticky ends" where they are uneven in length.
