What is complementary base pairing? Explain why complementary base pairing is necessary to maintain the double helix shape of the DNA molecule.

Answers

Answer 1

Answer:

A complimentary base pairing is how adenine can only bond with thymine and how guanine and cytosine through hydrogen bonding. It is necessary to maintain the double helix shape. Because it is opposite, that is why the DNA is that shape. It is anti parallel due to the Complementary base pairing.

Answer 2

Adenine can only bond with thymine and guanine with cytosine via hydrogen bonding. It's important to keep the double helix shape. Complementary base pairing causes antiparallelism.

Why complementary base pairing is necessary?

Base pairs linked to a sugar-phosphate backbone form the double helix structure of DNA.

DNA is composed of four nitrogenous bases: thymine, adenine, guanine, and cytosine. Guanine and cytosine are linked by three hydrogen bonds, while adenine and thymine are linked by just two. The term for this is complimentary base pairing.

Complementary base pairing is critical for the formation of the helical helix of DNA because it permits the base pairs to be organized in the most energetically favorable manner. It is also essential for replication since it permits semiconservative replication.

In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.

Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.

What is soil erosion?

The removal of the top of the soil by water, wind and human activities has been called soil erosion. The reason due to which soil erosion takes [place is that trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.

Soil erosion has happens when the dirt has been exposed to the high winds, heavy rains, and rushing water. In few circumstances, human activities, like farming and land clearance, expose soil to erosion. Soil erosion has been considered as the removal and transfer of the top layer of soil from its original location to another due to high winds and fast-running precipitation.

Therefore, Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.

In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.

A researcher attempts to use a segment of ribosomal RNA as a molecular clock to calculate the date of the last common ancestor of two species. He finds that the two species diverged from a common ancestor 150 million years ago. These particular species have abundant fossil records that strongly suggest that these species diverged 100 million years ago. Which of the following answer choices best describes a reason for the discrepancy in the date of the last common ancestor of these species?

A. Ribosomal RNA is not a reliable molecular clock and should not be used for dating.
B. The neutral mutation rate used in calculating the last common ancestor date may not have been accurate.
C. It is highly likely that the two organisms did not share a common ancestor, so the results are invalid.
D. A large portion of the ribosomal RNA is not vital to survival, so it is not likely to be well preserved.

State reason(s) why ash should or should not be used in making compost

Answers

Answer:

Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature.  But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.

Predict how a loss of function mutation in the p53 gene is most likely to affect the cell cycle in response to DNA damage. Justify your predictions.

Answers

Answer:

The cell cycle of cell multiplication is regulated by three types of genes, the regulatory genes that control mutations, the generic promoters of cell replication, and genes that inhibit cell replication.

The balance between these three types of gene group are what result in a good multiplication of cells without mutations or neoplastic developments.

The p53 gene is one of the genes that is considered as the guardians of the genome, since it is in charge of corroborating and regulating mutated cells, in this way it inhibits their progression in the cell cycle by putting a stop to not replicate defective genes or genes with alterations.

Explanation:

The p53 gene is one of the most altered genes seen in malignant neoplasms, since by altering our guardian of the genome many mutations overlook and more carcinogenic potential will have neoplastic tissue.

In the three groups of genes that we write, all three have a fundamental roll in the cell cycle, but in order to trigger malignant neoplasms, it is necessary that there be a continuous series of gene mutations in these three groups, it is not enough with the mutation of a single gen.
