The Lock-and-key mechanism was first proposed by Emil Fischer which described as the enzymatic reactions whereby an enzyme with a single substrate binds temporarily to form a substrate complex.
The lock-and-key mechanism is usually associated with the complementary shapes of an enzyme with a single substrate, wherein the lock that is being referred to is the enzyme and the substrate is the key. One right sized substrate (key) fits into the active site (key hole) of the enzyme (lock).
The active site which is mentioned above is structurally complementary to the substrate. This is the temporary binding site on the enzymes. Just like a lock and key, the enzyme as the lock and the substrate as the key is said to fit together.
<u>Answer</u>:
Option d. many small changes can create a whole new species
<u>Explanation</u>:
In the natural selection when the animals gets adapted in a better manner, they tends to thrive in and gets the ability to reproduce more which leads to the formation of the new bigger species. It leads to a change when the individual with few characteristic have the survival chance more also the reproductive rate as compared to others individuals in the group and also passes these inheritable genetic traits to the offspring.
Answer:
The molecule that contains the codon during translation is mRNA or messenger RNA (option C).
Explanation:
The mRNA is the product of the transcription of the information contained in the DNA, originating a nitrogenous base sequence complementary to the sequence present in the originating DNA.
The sequence of nitrogenous bases in the mRNA is translated into <u>fragments of three nitrogenous bases</u>, called triplets or codons, each of which encodes a specific aminoacid, which will be incorporated during protein synthesis, in the order previously determined.
