Methane gas must be removed from landfills because _____.

Biology
1 answer:
ZanzabumX [31]3 years ago
5 0

Answer:

it is highly explosive is the correct answer.

Explanation:

Methane gas must be removed from landfills because it is highly explosive.

Methane gas is highly explosive because it carries chemicals that are present at an explosive level.

Methane gas concentration in landfills is about 50 percent higher than its Upper Explosive Limit and it is expected to cause an explosion hazard.

landfill gas(methane gas) is produced due to decomposing the waste in landfills and landfills gas is dangerous as it results in the greenhouse effect.

An operon is controlled by a repressor. When the repressor binds to a small molecule, it binds to DNA near the operon. The opero
larisa [96]

Answer:

Negatively repressible.

Explanation:

A control which occurs through repressor is known as negative control which may be inducible or repressible.

When a small molecule named as allolactose binds this repressor it leads to allosteric repulsion which removes repressor from the operator as a result of which RNA polymerase can start transcription. Allolactose is therefore known as inducer because it induces lac operon expression.

But here, the operator is active (induced) already so there is no need to induce the operon which means that it can only be repressed so that transcription could stop. So the answer is negatively repressible operon.

E. coli DNA polymerase III is both highly accurate and highly processive. a) Describe how Pol III avoids the incorporation of im
kogti [31]

Answer/Explanation:

DNA polymerase is the enzyme responsible for replicating DNA. It is hugely important that is performs its functions accurately, as if incorrect bases are incorporated this can lead to mutations that disrupt the structure and function of genes. It adds nucleotides in a 5' - 3' direction only.

DNA polymerase III also has high processivity, which means that for every time it binds DNA, it is able to add many bases before it becomes dissociated.

A. DNA polymerase avoids the incorporation of improperly paired nucleotides in two ways:

  • The first way depends on the structure of the enzyme. If the nucleotide that the enzyme is in the process of adding is not complementary to the template, then the nucleotide will not align with the template, and thus it is more inefficient to add. This inefficiency means the nucleotide is more likely to leave the active site before it is added, and DNA polymerase can replace it with the correct nucleotide.
  • It also has proofreading capabilities. This means, when an incorrect base is added, it recognises the error and can fix this. It can do this because it possesses 3'-5' exonuclease activity. That means, it can chop out incorrectly added bases.

B. Ribonucleotides are the nucleotides that are incorporated into a growing RNA molecule. They are different from deoxyribonucleotides because of the differences in the sugar backbone (ribose vs deoxyribose). Their incorporation would disrupt the structure and function of the DNA, leading to problems with transcription and replication.

DNA polymerase avoids incorporating these nucleotides primarily because of the structure of the enzyme. Ribonucleotides cannot fit into the active site of DNA polymerase due to what is called a "steric filter" or "steric gate". This gate/filter function is performed by specific amino acid residues which usually have a bulky side chain and thus block the incorporation of the 2'OH of the ribose sugar (which is lacking in the deoxyribose sugar)
