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.
Spermatozoa. Hope this helps! (:
Answer:Eukaryotes only (A) and (D), bacteria only (E) both (B) and (C).
Explanation:
(A) Only eukaryotes have a nucleus.
(B) Both replicate the DNA before performing cell division, so each cell keeps a copy.
(C) This structural feature is called centromere in eukaryotes and in bacteria this role is played by the origin of replication.
(D) Centromeres are eukaryotes exclusive.
(E) Only bacteria have a replication origin.
Based on the information above, the correct answer to the question would be a. Percy will likely make an external attribution. Since he does not remember anything that would cause him to think that he can be a reason why one of his windows is broken, then he most probably will attribute it towards an external event.
