Answer: organism and reproduce and produce offspring
DNA
Nucleic Acids are the basis for the storage and transmission of hereditary information in all cells. Determines a cell's function and manufactures proteins & enzymes. Encodes instructions for making proteins and RNA. DNA stores the “operating instructions” for a cell.
<u>Answer:</u>
<em>The intertidal zone is a region of extreme conditions and the organisms should have special mechanisms to cope up with the extreme conditions.
</em>
<u>Explanation:</u>
Low tides expose an intertidal zone to air while high tides cover the intertidal zone with ocean water. When exposed to air the intertidal region is <em>directly exposed to the sun and there will be high temperature. </em>
Thus the animals have to cope up with the extreme heat and also have to face colder environment when under the sea. <em>Since there is change in salinity the organisms have to handle this as well.</em>
Some animals with shells close their shell tightly to seal moisture. Animals like <em>snails and crabs have thick outer covering to prevent water loss by evaporation. </em>
Organisms like leaf barnacles cluster together to avoid individual exposure. <em>Animals like sea stars cling to the rocks to avoid being washed away by the waves.
</em>
One option is that the samples run through gel electrophoresis is too small to be recognized (shorter strands of DNA travel further through the gel and larger strands travel shorter). The other option in that the restriction enzyme did not cut the DNA in the proper spot or there was a mutation in the bases that allowed for a mistake in the cutting; that is why there are 800 base pairs in one sample (that's a lot) An example of a mutation is that lets say the restriction enzyme was supposed to cut at the second G in GGACC. But if that G was turned into an A, then the restriction enzyme wouldn't cut there.
For number 5, you might have 800 because of the restriction enzyme cutting it wrong, a mutation that allowed for the cutting to not take place, or a fault in the sample taking.
I am an AP Biology student right now in Wisconsin. I just finished that worksheet this morning :) anymore questions just hit me up
