Assume that an error has occurred during dna replication, and the new non-template dna strand has a mutation in the base sequence, such that the nucleotide that is in bold and underlined (*) has been added to the normal sequence. decipher the new "message." non-template dna strand +1 * 5’

3’

a. what is the sequence of the new "message? " use the single letter codes for each amino acid to decipher the "message." again, show all your work.

b. what type of mutation point or frameshift has occurred? you perform an enzymatic rate of reaction analysis on 2 mutants of an enzyme and obtain the following data (note: these are not the mutants above)

The enzyme that is responsible for adding nucleotides to the growing DNA molecule is called DNA POLYMERASE.

The principal role of DNA polymerase is to carefully and accurately add the right nucleotides to the growing DNA molecule in order to make sure that the genome is accurately replicated and the genetic information are maintained.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

explanation:
