Answer:
It is difficult to obtain a final conclusion with this information, but it is possible that the sample doesn't contain living organisms whose genetic material is composed of DNA. Another possible reason for this result is that the DNA extraction protocol used in the experiment is not suitable for this sample.
Answer:
a discovery by a human being
Explanation:
The correct answer would be a discovery by human being.
Penicillin existed in nature and was only discovered, albeit accidentally, by Alexander Fleming.
It is different from<u> technological innovation because the latter requires the synthesis of products that are not in existence already or improvement on a product that has been created before</u>.
Discovery is also different from advancement in technology. <u>The latter refers to the process of inventing, innovating, and spreading technological processes in society.</u>
Discoveries are usually natural and are not in any way an invention. However, advancement in technology can aid discoveries.
The role of the ddNTPs is to stop replication because the next nucleotide in the growing strand cannot bind to them. It is for that reason that ddNTPs are fundamental in Sanger sequencing.
<h3>Sanger sequencing</h3>
Sanger sequencing is a technique used to sequence and thus determine the nucleotide order of a DNA chain.
This methodology (Sanger sequencing) was designed by Frederick Sanger in 1977.
In Sanger sequencing, the ddNTPs are used to stop the synthesis of a DNA strand due to the lack of a free hydroxyl group (OH) which is required for the replication of DNA.
