Beadle and Tatum's concept of the gene has been further refined to state which of the following most correct and current idea?

Biology
1 answer:
Rufina [12.5K]3 years ago
3 0

Answer:

a. one gene - one enzyme

Explanation:

Genes are connected to enzymes was first suggested by Sir Archibald Garrod. Later on, Beadle and Tatum carried out genetic studies on <em>Neurospora </em>and confirmed Garrod's hypothesis.

The link between genes and enzymes was called “one gene-one enzyme hypothesis”.

But this hypothesis is not accurate and changed because some proteins are encoded by genes are not enzymes. Some genes do not encode a whole protein but a subunit of a protein. In general, one polypeptide (a chain of amino acids) encoded by one gene.

The older crust in this case would be at point D, the newest at point A.
umka2103 [35]

Explanation:

New ocean crust is formed at the mid ocean ridges. The new crust is then pushed away from the ridge as newer crust comes to the surface. The ocean crust then spreads out enlarging the ocean. The farer away from the ridge the ocean crust is the older the crust

The lac operon can be regulated by two distinct methods. Which of the following statements are correct?The lac operon can be act
Ad libitum [116K]

Answer:

  • The lac operon can be activated by the binding of allolactose to the repressor protein, releasing it from DNA and thereby allowing for transcription to occur.
  • In response to low glucose levels, cAMP is upregulated; the binding of cAMP to the cAMP receptor protein triggers the activation of the operon.

Explanation:

Lactose operon or lac operon  (includes lacZ, lacY and lacA genes) is found in some bacteria and the products of its genes are involved in lactose metabolism. So, this operon is active (genes are transcribed) when lactose is present and glucose is absent (or at low level). The operon is regulated by the lac repressor which acts as a lactose sensor and catabolite activator protein (CAP) which acts as a glucose sensor.

When there is lactose (in the form of allolactose) lac repressor detects it and stops being repressor. This enables transcription.

CAP detects glucose (via cAMP) and activates transcription when glucose levels are low.
