Answer:
D) The encoded protein contains four repeats of a specific sequence.
Explanation:
The polymerase chain reaction is a technique used to replicate or amplify the amount of DNA sample.
The technique employs running the DNA samples on the gel through which the DNA samples run based on their sizes.
The large-sized DNA fragment runs to a less distance whereas the small-sized DNA run to a large distance.
In the given question, four sizes of DNA bands are formed in the ratio of 1:2:3:4 which shows that the proteins encoded by this DNA have four repeats of a specific sequence of the template strand. This was confirmed when the largest band sample was again used as a sample of PCR and the PCR resulted in the four bands in similar 1:2:3:4.
Thus, Option-D is the correct answer.
Answer:
Sympathetic nervous system
Explanation:
The sympathetic nervous system of the autonomic division prepares the body for stress or emergency conditions by generating the “fight-or-flight” responses. The sympathetic nervous system triggers the release of stress hormones from the adrenal medulla to generate the set of physiological responses.
There is dilation of the pupil, and an increased rate of heartbeat and increased blood pressure. Other responses include dilation of airways and dilation of blood vessels that supply blood to skeletal muscles, heart muscles, liver, etc. Under the given emergency condition, the sympathetic nervous system of Meghan was activated to generate the fight or flight response.
The answer to that would be archaebacteria since they are prokaryotes (no nucleus) but so is Eubacteria, however archaebacteria can live in very harsh conditions.
Answer:
Between ph7 and ph 11
Explanation:
The optimum pH level for this is at pH7 because the number achieved was 350 product molecules per Minute
Answer:
Blood vessels in the heart dilate to increase blood pressure.
