A new nucleotide can only be added to the 3' end of a growing dna strand. dna therefore always grows in the 5' to 3' direction.
Define nucleotide.
Nucleotides are organic molecules made up of a phosphate and a nucleoside. They serve as monomeric units of the essential biomolecules found in all life forms on Earth, deoxyribonucleic acid(DNA) and ribonucleic acid polymers.
Define DNA.
Deoxyribonucleic acid(DNA) is a polymer made of two polynucleotide chains that coil around one another to form a double helix and which contains the genetic material necessary for all known creatures, including many viruses, to develop, function, grow, and reproduce. Nucleic acids include DNA and ribonucleic acid.

Answer:
Woman's genotype is AO
Man's genotype is BO
Explanation:
For a woman with blood group A and a man with blood group B to give birth to a child with blood group O. Their genotypes will be:
Woman's genotype is AO
Man's genotype is BO
The can have a child with blood group A, B, AB and O
1/4 will have type AB blood group;
1/4 will have AO, which is type A blood group;
1/4 will have BO, which is type B blood group;
1/4 will have OO, which is type O blood group

Answer:
Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity.
Explanation:
It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace amounts of other gases, and water vapor. This mixture of gases is commonly known as air.
Answer:
The answer is E.) Lithosphere, Asthenosphere.
Explanation:
Tectonic plates belong to the layer called Lithosphere. The tectonic plates float on the Asthenosphere which is below the Lithosphere and more fluid than the crust.
From the Earth's surface to the its center we can say that the inside of the Earth is divided into four layers which, starting from the top , are:
i) the crust
ii) the mantle, (Lithosphere, Asthenosphere , Mesosphere)
iii) the outer core
iv) the inner core.
The tectonic plates are part of the Lithosphere and are constantly moving even though the crust is fairly solid. This is because the inner layers
( Asthenosphere , Mesosphere) are much are fluid and are constantly moving which tends to move the tectonic plates. When the tectonic plates collide they do so with tremendous force which leads to earthquakes and sometimes tsunamis as well resulting in a loss of life and property.
