This problem has been solved! see the answeryou have a dna sequence of 1600 bp. to characterize it, you decide to make a restriction map. cutting with the first enzyme, you show by electrophoresis that the fragments produced are 400 and 1200 bp respectively. after using the second enzyme, you recover 700-bp and 900-bp fragments. after treatment with both enzymes, fragments were 300, 400, and 900 bp. which is the correct map? you have a dna sequence of 1600 bp. to characterize it, you decide to make a restriction map. cutting with the first enzyme, you show by electrophoresis that the fragments produced are 400 and 1200 bp respectively. after using the second enzyme, you recover 700-bp and 900-bp fragments. after treatment with both enzymes, fragments were 300, 400, and 900 bp. which is the correct map? a.) -400/--/300 .) -300-/--400--/--.) -400-/300-/.) -400-/-100/--300--/900e.) -900 /400--/

C.) -400-/300-/---900

Explanation:

The full DNA fragment has 1600 bp.

1600

After cutting with the first enzyme two smaller fragments are generated: 400 and 1400 bp.

400/1200

After cutting with the second enzyme two smaller fragments of 700 and 900 bp are generated.

700/900

And after treatment with both enzymes, fragments were 300, 400, and 900 bp:

400/-300-/900

Developed a way to protect their foliage. Instead of flat leaves, pine trees have needles. These needles are the key to the Winter survival of the pine tree. Needles cut evaporation sotrees can save water!
Cacti have sines instead of leaves because they help protect them from getting eaten and they don't need leaves because they store water inside themselves. 
They both have adapteations to help them servive in very harsh conditions. Cacti use their adaptations to survive in scourching heat and pine trees can servive in freezing cold.
