Answer:
The correct answer is- Nirenberg and Heinrich, 1961.
Explanation:
Experiments by Marshall Nirenberg and Heinrich Matthaei in 1961, began to decipher genetic codes and state about the 64 triplet codons in the genetic code by using mRNA from DNA to translate into specific amino acids in our biological system.
Their experiment helps to decode or crack the code of DNA by establishing the first codon out of 64 triplet codes which are UUU codes for phenylalanine. In the future, the same approach is used to find other amino acids.

As verbs the difference between mounting and staining is that mounting is while staining is . As an adjective mounting is that continues to mount; steadily accumulating. As a noun mounting is something mounted; an attachment.
Answer:
Mutation
Explanation:
I believe it is a mutation. A mutation is when the DNA is copied with a small mistake. Ex: AGCC => AGGC
Then, after a mutation, the DNA isn’t exactly identical because of this mistake in the DNA after copied.

Answer:
The best example of environmental influence that would most likely result in natural selection is that a food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.
Explanation:
Among the environmental factors that can influence natural selection at a given time is the availability of food. Natural selection, from the point of view of evolution, is influenced by adverse environmental conditions, being food shortage one of them.
In conditions of food shortage in a pond, as in the example of the frog population, only the most apt will be able to take advantage of nutritional resources, while the less apt will not be able to survive. The ability to survive with little food available becomes an inherited trait that will be passed on to future generations.
In any case, tolerance to adverse conditions becomes adaptation, which translates into survival and reproductive success.
- <em>The other options are not correct because </em><u><em>none of them show environmental pressure that can lead to natural selection</em></u><em>.</em>
