If the DNA sequence TTCACG is transcribed to AAGGC, what type of mutation has occurred?
kenny6666 [7]
The answer is d. deletion.

If the DNA sequence is TTCACG, it is expected to be transcribed into AAGUGC.
But, it was transcribed into AAGGC. If we count nucleobases, a transcribed sequence has 5 nucleobases, while DNA sequence has 6 nucleobases. These means that deletion happened.
If insertion occurred, there will be 7 nucleobases in transcribed sequence. In substitution or translocation, the transcribed sequence will be the same size, but with different sequence than the DNA sequence.

What led to food shortages in the Philippines
Sloan [31]

The economy of the Philippines is heavily dependent on agriculture. Most of what constitutes food security in the country depends on the agricultural sector; therefore, challenges faced by Filipino farmers and fishermen often have a detrimental effect on food security in the country.

The challenge often does not come from the quality of terrain, as seen in Djibouti. The Philippines is full of fertile lands ready to be cultivated for agriculture. It is the inconsistency of supply due to external disruptions from both controllable and uncontrollable factors that pose a challenge to food availability in the country.

The Philippines’ location in the middle of the Pacific makes the country susceptible to typhoons and droughts, some with devastating effects. Last year, a dry spell caused by the El Nino phenomenon destroyed 349,630 metric tons of crops, worth about On the other hand, the string of typhoons that ravaged the country at the end of the year notably slowed down the national agricultural growth rate

You are treating a 13-year-old female who has a broken stick impaled in her forearm. there is some minor bleeding from the site.
yan [13]

Answer:

apply direct pressure to the injury site while manually stabilizing the stick in her arm

Explanation:

Spinal immobilization can generally be explained  as the use of adjuncts such as cervical collar, that are  being applied to minimize movement of the spinal column.

In this case, since the area where the girl is injured is the forearm, it has no direct connection with the spinal column, this means that, the cervical spinal immobilization is unnecessary.

Therefore, there should be direct application of pressure to the injury site while manually stabilizing the stick in her arm.
