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.

2. Copy/paste and align the first 5 bases of all introns. Which bases are conserved near intron start ("donor site")?
Delicious77 [7]

Answer:

This question is incomplete

Explanation:

Introns are non-coding regions of a DNA that removed by RNA splicing prior to translation. Alignment is usually done between sequences to see and understand the identity and similarity between two or more sequences.

A region/base is said to be conserved if there is  NO change in any base in that particular region. A multiple sequence alignment (MSA) can be used to align the donor sites of all the introns to see the bases that have not "changed" (and still remained in there exact position) hence conserved across all the donor sites.

NOTE: The donor site of an intron is the 5' end, thus the first five bases in the 5' end are to be used here

Temperatures are rising world-wide due to greenhouse gases trapping more heat in the atmosphere.

• Droughts are becoming longer and more extreme around the world.

• Tropical storms becoming more severe due to warmer ocean water temperatures.

• As temperatures rise there is less snowpack in mountain ranges and polar areas and the snow melts faster.

• Overall, glaciers are melting at a faster rate.

• Sea ice in the Arctic Ocean around the North Pole is melting faster with the warmer temperatures.

• Permafrost is melting, releasing methane, a powerful greenhouse gas, into the atmosphere.

• Sea levels are rising, threatening coastal communities and estuarine ecosystems.

Which of the following is not a good polling technique? A. asking clear questions B. using a push poll C. using a large sample D
svetlana [45]
Question is which is NOT a good technique.
Answer is "B" and here's why:

A) Clear questions -- good. People understanding the question will answer accurately.
C) Large sample size -- good. Answers will be more accurate with more people asked (like if you flip a coin 1,000 times its going to be closer to 50% heads than if you only flipped it twice)
D) Random sample -- good. Avoids your own bias in choosing who to ask.

B) Push poll -- bad. Pretends to be unbiased, the pollster's real objective is to get a person thinking in a way that is to their advantage. Some political candidates do this just before elections.

If a solution process is exothermic, how does the energy required for dissolving the solute compare with the energy released?
Misha Larkins [42]
If a solution process is exothermic, the energy required for dissolving the solute compare with the energy released is that, the energy requiredis less than the energy released. When we sayexothermic, heat is evolved. On the other hand,when heat is absorbed, this is called endothermic.
