George Beadle and Edward Tatum used mutant strains of Neurospora to formulate the one-gene-one-enzyme hypothesis. Researchers la

ter updated this hypothesis to propose that one gene encodes one polypeptide because proteins can have multiple subunits. Consider a heterodimeric protein. How many genes are required to form this protein?
(A) two
(B) four
(C) six
(D) three
(E) one

Answer:

(A) two

Explanation:

A heterodimeric protein consists of two polypeptides (a polypeptide is a  chain of amino acids) that differ in amino acid composition, number or order in the chain sequence. Each polypeptide makes a different subunit of the protein.

One gene encodes one polypeptide, so if the protein has two different polypeptides, two genes are required to form this protein.

ExtremeBDS [4]

Answer: C. Miller and Urey showed that inorganic compounds could combine  to form the building blocks of living cells.

Explanation:

The Miller and Urey were the two scientists who created the atmospheric conditions that were expected to be present on primitive earth. They demonstrated that several organic compounds have been formed spontaneously from the inorganic compounds like water, ammonia, methane and others.

The exposure of mixture of inorganic compounds by the lightening lead to the formation of organic molecules like amino acids which are the building blocks of life. This was similar to the penetration of earth atmosphere by UV radiation producing the organic compounds from inorganic molecules.

Yellowfin tuna, or Thunnus albacores, are large sport fish that are found in tropical and subtropical waters around the world. T
Ber [7]
<span>The correct answer is 'secondary consumer’. This is because the yellowfin tuna eats herbivorous fish (these are primary consumers - they only eat plants, which are producers) and take refuge from predators. This shows they are not tertiary consumers, as tertiary consumers are at the top of the food chain.</span>

Explain how the triplet code of dna is transcribed and translated in the synthesis of proteins
timama [110]
Ok this is going to be a long answer lol


Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). During translation, an mRNA sequence is read using the genetic code, which is a set of rules that defines how an mRNA sequence is to be translated into the 20-letter code of amino acids, which are the building blocks of proteins.



During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA

I hope this helps :)
