Another step in PCR requires small single-stranded DNA primers to anneal to a target sequence on denatured DNA. Two primers are

used. Ideally these primers will have similar melting temperatures. The melting temperature is defined as the temperature at which 50% of the DNA is in the single-stranded form. Which of the following primers will have the highest melting temperature?
A. GGGGAAATTTCCCC.
B. AAAAGGGCCCTTTT.
C. AAAAGGCCTTTT.
D. GGGAAATTTCCC.

Answer:

A. GGGGAAATTTCCCC.

Explanation:

When calculating the melting temperature in the DNA primers, we use the formula:

( 2 × ( A + T ) ) + ( 4 × ( G + C ) )

From the above formula; it is obvious that G and C have a greater tendency of participation when determining which DNA primers that have the highest melting temperature.

A.  GGGGAAATTTCCCC = 8

B. AAAAGGGCCCTTTT   = 6

C. AAAAGGCCTTTT        = 4

D. GGGAAATTTCCC        = 6

From the given options, we can see that option A have the highest component of G and C.

Question 2 of 10<br> Which of the following should be included in a good conclusion?
rjkz [21]

Answer:

How to write a conclusion

An effective conclusion is created by following these steps:

Restate the thesis: An effective conclusion brings the reader back to the main point, reminding the reader of the purpose of the essay. However, avoid repeating the thesis verbatim. Paraphrase your argument slightly while still preserving the primary point.

Reiterate your supporting points: Aside from restating your thesis, you should also reiterate the points that you made to support it throughout the paper. But instead of simply repeating the paper's arguments, summarize the ideas.

Make a connection between your opening and closing statements: It's often effective to return to the introduction's themes, giving the reader a strong sense of conclusion. You can accomplish this by using similar concepts, returning to an original scenario or by including the same imagery.

Provide some insight: Your conclusion should leave the reader with a solution, an insight, questions for further study or a call to action. What are the implications of your argument? Why should anyone care? You'll want to answer these types of questions here and leave your audience with something to think about.

Why biotic and abiotic factors are important to an ecosystem ​
Nikitich [7]
Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem. Abiotic factors are especially important because they directly affect how organisms survive.

How does carbon dating tell us how old a bone is
Neko [114]

Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old. It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.

Do you think monogamy and polygamy are reproductive strategies? In terms of species survival, what are the advantages and disadv
sdas [7]

Answer:

Indeed, both monogamy and polygamy are reproductive strategies adopted by the different species of the animal world.

Explanation:

Polygamy implies the adoption of a unique and stable partner by an individual, with which in principle it will reproduce. Different species, including humans or penguins, in addition to maintaining the same pair for reproductive purposes, generate bonds of coexistence.

Other species (in fact, most animal species) are not guided by this type of relationship, but fulfill their reproductive functions in a random way, that is, with several individuals of the same species in a random way, which is called polygamy. In this case, there is a constant change in the reproductive couple, which responds to multiple factors such as for example a gender disproportion within the species (for example, many females and few males would make those few males have to comply reproductive functions with several females during the mating period), or due to the non-sedentary nature of life of these species.
