(a) Describe the process by which cells produce the FGF5 pre-mRNA , and include the location
Svetlanka [38]

Answer:

Explanation:

mRNA (messanger ribonucleic acid) is produced through the process called transcription in the nucleus. Transcription make ribonucleic acid from deoxyribonucleic acid. The enzyme RNA polymerase creates an RNA molecule that is complementary to the template DNA coping all the information on the DNA into the mRNA formed and 3' to 5' cap are added to stabilize the RNA after which this mRNA then moves from the nucleus where it was produced to the ribosome in the cytoplasm for translation of the information that is coded in the bases.

FGF5 is a gene that is encoded in the DNA.

You start a PCR with 1,000 molecules of DNA, an excess of primers and an excess of nucleotides. The PCR works perfectly and each
arsen [322]

Answer:

2.048 x 10^6 No. Of Copies

Explanation:

The DNA replication in a PCR works exponentially by using the 2^n where n represents the number of cycles.

For one molecule of DNA = 2^11 = 2048 No. Of Copies

For 1000 Molecules of DNA = 1000 x 2048 = 2.048 x 10^6 No. Of Copies

An owl has good night vision because its eyes can detect a light intensity as small as 5.0 × 10-13 W/m2. What is the minimum num
Lady bird [3.3K]

Answer:

Thus, the minimum number of photons per second is 77.34

Explanation:

Light intensity, I_{min} =  5\times 10^{-13} W/m^{2}

Pupil has a diameter, d = 8.5 mm

                                      = 8.5 x 10^{-3} m

Radius of the eye, r = 4.25 x 10^{-3} m

∴ Area of the eye, A = \pi .r^{2}

                                 = 3.14\times \left ( 4.25\times 10^{-3} \right )^{2}

                                = 5.6\times 10^{-5} m^{2}

Let P_{min} be the minimum number of photons.

Therefore, P_{min} = I_{min} x A

                                              = 5\times 10^{-13} x 5.6\times 10^{-5}

                                             = 2.8\times 10^{-17} W

Thus the minimum number of photons is given by

N_{min}=P_{min}/E

where E = hc/\lambda

             = \left (6.63\times 10^{-34}\times 3\times 10^{8}  \right )/548\times 10^{-9}

            = 3.62\times 10^{-19} J

Therefore, N_{min} = \frac{2.8\times 10^{-17}}{3.62\times 10^{-19}}

                                              = 77.34 photons per second

Thus, the minimum number of photons per second is 77.34
