"<span>Appearance of a trait in a population does not solely depend on its dominant or recessive nature" is the correct choice among the choices that are given in the question. The correct option among all the options that are given in the question is the second option or option "B". I hope that the answer has helped you.</span>
Answer:
Ribonucleotides (RNA) and deoxyribonucleotides (DNA). See more details below, please.
Explanation:
Ribonucleotides are the nucleotides of the RNA (they have pentose, ribose and nitrogenous base, except for Thymine; they contain uracil). Deoxyribonucleotides are the nucleotides of DNA (they have pentose, deoxyribose and nitrogenous base, they have Thymine).
Gene transfer via transduction could be beneficial if the donor has a new gene that could produce a useful protein. This protein could be an enzyme with various effect like
1 digesting food(fermentation),
2 digesting drug(drug resistance) or
3 toxin that could kill the nearby cells(to decrease food competition).
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.
