How does the double-helical structure of DNA explain how the molecules can be copied or replicated?

Damm [24]

Answer:

A. Because of base pairing, each strand has all the information to serve as a template for the other strand.

Explanation:

Deoxyribonucleic acid (DNA) is a molecule composed of two antiparallel polynucleotide chains. This double helix serves as a template for its own duplication. DNA templating refers to the process by which a portion of the DNA molecule in a single strand is used as a template to be copied by complementarity base pairing. According to base-pairing rules, Adenine (A) always pairs with Thymine, while Guanine (G) always pairs with Cytosine (C). These nucleotide bases are each linked with their complementary base by hydrogen bonding. When base pairs separate, the hydrogen bond acceptor and donor groups of each strand allow the addition of nucleotides and synthesis of new DNA strands, a process catalyzed by specialized enzymes (DNA polymerases).

artcher [175]

<h2>Himalayas </h2>

Explanation:

Once, all the world’s landmass was connected, forming one super-continent known as Pangea
About 200 million years ago, tectonic forces broke apart this giant continent into pieces, eventually forming the continents that are known today
As convection currents worked independently on the plates associated with these new continental pieces, the plates and their respective continents began to drift across the globe to their present-day geographical locations
Eighty million years ago, India was approximately 6400 km south of the Eurasian plate, separating the two was the Tethys Sea
The Indo-Australian tectonic plate – containing the continent of Australia, the Indian subcontinent, and surrounding ocean – was pushed northward by the convection currents generated in the inner mantle
For millions of years, India made its way across the sea toward the Eurasian plate
As India approached Asia, around 40 million years ago, the Tethys Sea began to shrink and its seabed slowly pushed upwards
The Tethys Sea disappeared completely around 20 million years ago and sediments rising from its seabed formed a mountain range
When India and Tibet collided, instead of descending with the plate, the relatively light sedimentary and metamorphic rock that makes up the subcontinent of India pushed against Tibet, forcing it upwards, and created a massive mountain fold, The Himalayas
This process hasn’t stopped, the Indo-Australian plate is still moving toward Eurasia, still pushing Tibet upwards
The Himalayas continue to rise by an average of 2 cm each year and the highest mountains are only getting higher

Q: A: Which of these best describes what occurs during cytokinesis?

Nitella [24]

The correct answer is the cytoplasm is divides between the two new daughter cells Cytokinesis is the final stage of the cell cycle in which cytoplasm, the material within the living cell, divides into two daughter cells.

1.

Allushta [10]

1. The answer is "<span>the energy required to start the reaction".

</span>This energy is called as activation energy of the reaction. If the activation energy is high, reaction is slow. Enzymes help to carry out the reaction by a new path by reducing the activation energy. But the energy of reactants and the products remain as same as without enzyme.

2. The answer is "reaction in cells would be too slow to sustain life<span>".

</span>If the activation energy is very high for the reaction, then that reaction will be very slow and will require more time<span> to complete the reaction. Then survival is very low. Hence, the roll of enzymes is very important to sustain life.</span>
