During the DNA synthesis via PCR, polymerization occurs in 5’-3’ direction. This means that enzyme DNA polymerase which synthesizes a new DNA strand is complementary to the DNA template strand (3’-<span>5’ direction). 5’ phosphate group of the free nucleotides which are added is attached to the 3'-hydroxyl group at the end of the elongating DNA strand.</span></span>
Answer:
Option C
Explanation:
For chagarff's rule, it clearly states that DNA from any cell of any organisms be it prokaryotes or eukaryotes should have the basic 1 (purine): 1 (pyrimidine) ratio. Particularly, amount of adenine should be equal to thymine, and guanine equal to cytosine. This is in particular reference to organisms that have double stranded DNA.
Answer:
Compound: These are made of the various type of same or different elements. These elements show a specific ratio in a particular compound.
The physical properties are traits of a particular compound or element that can be observed physically like the state of matter, color, odor, and other. The chemical properties and physical properties of compounds and elements they formed are different.
It is not comparable as the elements have no or very little individual value in a compound. For instance, water made of hydrogen and oxygen, where water is liquid and constituents are gas.
The adaptations of the sperm and egg that allow fertilization to take place, and copulation occurs for the sperm to be deposited. These sperm penetrate the cervix and travel to the fallopian tube. There, they must find an oocyte, which is released in the process of ovulation.
<h3>What is fertilization and embryo development?</h3>
In the first weeks after fertilization, the zygote makes many changes and develops rapidly. The first eight weeks of development is known as the organogenic period and is the embryonic stage of development. This period is a crucial phase of development for the embryo's organs.
With this information, we can conclude that The first three days of embryonic development occur in the fallopian tube as the embryo moves from the ovary to the uterus. Cell division continues and forms a hollow ball of cells (the blastocyst). Six days after fertilization, the embryo begins implantation into the lining of the uterus.

Answer: Nucleotides
Explanation: DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
