Answer:
Principle of superimposition states that in undisturbed rock layers, the oldest rocks are on the bottom and the youngest rocks are on the top. Phenomena of withering is behind this process. The rocks are withered due to the effect of water and air. The sediments or soil particles gets accumulated at another location. The layers of sediments gets compact with time and leads to the formation of rocks. The rocks being older are covered by layers of sediments with course of time. These sediments gets compact again forms new rocks. By this way the new young rocks are formed over the older rocks.
Did you try the fact that the DNA sequences are copied
Answer:
1. A-C-G-G-T is <u>duplication</u>.
2. C-G-T is <u>deletion</u>.
3. A-G-C-T is <u>reordering</u>.
Explanation:
Your original sequence is ACGT. You compare the original sequence to the 3 mutations.
1. There 2 G's now, which means that the G has been duplicated.
2. The A is now gone in the front of the sequence.
3. The C and G were switched.
Explanation:
cAMP binds to protein kinase A and activates it, allowing PKA to phosphorylate downstream factors to produce a cellular response. cAMP signaling is turned off by enzymes called phosphodiesterases, which break the ring of cAMP and turn it into adenosine monophosphate (AMP).
