How are complementary strands of DNA held together?A) with hydrogen bonds connecting complementary bases

B) with phosphodiester bonds connecting sugars and phosphate groups

C) with hydrogen bonds connecting complementary sugars

D) with ionic bonds between sugars and phosphate groups

Answers

Answer 1
Answer:

The complementary strands of DNA are held together through hydrogen bonds that connect the complementary bases. Adenine pairs with thymine, and cytosine pairs with guanine. Phosphodiester bonds connect the sugars and phosphate groups along each strand, but they do not bind the complementary strands together.

The complementary strands of DNA are held together predominantly through hydrogen bonds that connect complementary bases. Among the four types of bases in DNA, adenine (A) always pairs with thymine (T) through two hydrogen bonds, and cytosine (C) always pairs with guanine (G) via three hydrogen bonds. Therefore, the correct answer is Option A) with hydrogen bonds connecting complementary bases. Option B is incorrect because phosphodiester bonds connect the sugars and phosphate groups along each backbone of a DNA molecule, but they don’t bind the complementary strands together. Option C and Option D are also incorrect as neither sugars nor ionic bonds play a substantial role in holding the complementary strands of DNA together.

What is the role of DNA in transmitting genetic information? Describe DNA’s important genetic role in a few sentences below.

Answers

Answer:

DNA is responsible for traits.

A section of DNA that codes for a specific trait is called a gene.

Half of your DNA comes from each parent.

Your traits are a combination of your parents’ traits.

DNA is the blueprint for proteins, which play many roles in the body.

Explanation:

Information to include in your answer on edge 2020
DNA is the molecule which holds the Genetic Information , it's like the blueprint for how the body will be built, you can call it the book of life. 

DNA is like a book written in a 4-letters-language, each three letter (Codon) can form a word , and these words can form sentences (Genes). And like any other type of sentences they contain some words which are not necessary (Introns) and crucial words (Exons). Moreover like any book, some chapters are not that necessary (Noncoding DNA). 

As a galaxy gets farther away from Earth, what happens?

Answers

As a galaxy gets farther away from Earth it gets faster.

Explanation:

First, moving away “from the Earth”. They certainly aren’t going away from the Earth. Everything is moving apart from everything else. No matter where you are in this expanding world, everything else will seem to be dropping from you. The space in within the galaxies is expanding! And the farther away a universe is the more space there is to increase so the faster the galaxy appears to move away from us.
After the Big Bang happened, the universe is constantly expanding. The Universe has expanded for around 13.7 billion years. The further a galaxy is, the faster it would move away from Earth. This principle is called the conservation of momentum.

Elaborate the relationship between light intensity and the daily rhythm of flowers opening.

Answers

Light energy is used by the flower to bloom that could allow the flower to remove its pollen for the pollination process. Also the light allows the flower or the plants to make food and that is why they bloom if its is portrayed be the light.

Explanation:

The greater the intensity of light, the more photons or photoelectrons there are and consequently the increase in photocurrent. Thus, the larger the energy, the greater the wattage of the light source.

Which of the following is NOT a source of point-source pollution? a. trash dumping c. pesticide runoff b. sludge dumping d. oil spill

Answers

Answer: c. pesticide runoff

Explanation: A point source pollution is the pollution which is caused by the pollutants whose source of origin can be traced back and further pollution can be prevented. A non-point source pollution is the one which cannot be traced back to it's origin and hence, cannot be prevented from further pollution. Trash dumping, sludge dumping and oil spill are the examples of point source pollution. But pesticide runoff is the example of non-point source pollution. A surface runoff will wiped off the pesticides from their surface and discharge them to the water body the source of origin of these pesticides will remain undetermined.
