Why are the large finches now living on the galápagos islands different from the original source population from a nearby islan
Softa [21]

Answer:

The reasons are explained below -

Explanation:

The large finches living on the Galapagos islands are different from the original source population from a nearby islands because of the following reasons -

  • A natural selection favored only the large finches because they are more fit to the current environmental conditions.
  • A genetic drift has been occurred in the two populations living on the nearby islands.
  • Due to the separation of habitat on both the islands, the gene flow between the two islands is reduced.

All the above listed reasons are responsible for the difference in the finches found on the two islands.

You add the following components (in the correct volumes and concentrations) to a tube to perform a PCR reaction Buffer Magnesiu
uranmaximum [27]

Answer:

b. False

Explanation:

These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.

The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.

For a PCR reaction to be performed a solution with some components must be prepared. These components are:

  • Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
  • Forward and reverse primers (to customize the start of the enzyme reaction)
  • DNA polymerase (Enzyme required for replication of desired DNA region.)
  • DNA Template (the DNA to be copied)
  • PCR-grade water
  • Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).

In the 1950s, when Watson and Crick were working on their model of DNA, which concepts were well accepted by the scientific comm
bogdanovich [222]

Answer:

The correct answer will be-

1. Chromosomes are made up of protein and nucleic acid.

2. Genes are located on chromosomes.

3. Chromosomes are found in the nucleus.

Explanation:

Watson and Crick are known for their findings on the structure of DNA in 1953. Their findings were motivated by the book called "What is Life?".

The book stated the concepts which were well accepted by the scientific communities that is the gene determines the trait which is located on the chromosomes proved by the experiments of Morgan.  

The chromosomes are the condensed structure present in the nucleus was suggested by the Nageli in 1884. The chromosomes are composed of nucleic acid and protein was also proved and was well-accepted fact.

But the genes are made up of DNA was not well accepted which was suggested by the experiments of Avery in 1940s.

Thus, the selected options are the correct answer.
