4. In gel electrophoresis, are the dna fragments attracted to, or repelled from the negative pole of the electric field?

Rzqust [24]

In the gel electrophoresis, the DNA fragments are repelled from the negative pole of the electric field.

<h3>What do you mean by Gel electrophoresis?</h3>

Gel electrophoresis may be defined as a technique that separates DNA, RNA, and proteins on the basis of their molecular weight.

As we all know, DNA fragments are negatively charged in nature, and hence they always move towards the positive pole of the electric field.

Therefore, in the gel electrophoresis, the DNA fragments are repelled from the negative pole of the electric field.

The invention of PCR make DNA fingerprinting possible because "PCR made it possible to produce enough copies for reliable tests".

Option: C

Explanation:

With the development of the PCR technique, DNA profiling has made enormous progress both in its distinguishing capacity and in its ability to survive information from very limited or damaged beginning samples. The PCR cycle mimics the biochemical mechanism of DNA replication yet restricts it to fragments of concern unique to DNA.

In the PCR method, the specimen of DNA is denatured by heating into separate polynucleotide strands. Two primers of DNA oligonucleotides are used for hybridization on opposite DNA strands to two matching nearby sites. Thus two new copies of the interest sequences are produced. Quantitative PCR methods allow accurate, high and automated calculations of the throughput.

Match each type of association with the best example commensalism mutualism parasitism amensalism A. A mold produces a chemical

Brums [2.3K]

A. A mold produces a chemical that kills bacteria without apparently benefiting. - amensalism

B. Aerobic bacteria in the human colon consume oxygen, making it possible for anaerobic species to survive. - commensalism

C. "Flagellates live in the gut of termites, feeding on the wood consumed by the termite and allowing the termite access to nutrition and energy in wood that they could not otherwise digest" - mutualism

D. "A helminth takes up residence in a human digestive tract, consuming nutrients" - parasitism

Explanation:

Amensalism is any relationship between organisms of different species in which one organism is inhibited or destroyed while the other organism remains unaffected.

Two examples of antibiosis amensalism are provided by the bread mold Penicillium and black walnut trees.

Amensalism is the association between organisms of two different species in which one is inhibited or destroyed and the other is unaffected.

Commensalism is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed.

Mutualism describes the ecological interaction between two or more species where each species has a net benefit. Mutualism is a common type of ecological interaction.

parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life
