Answer:
If a DNA strand has the base sequence TTCCGGAA the complementary strand has the sequence AAGGCCTT.
Explanation:
A DNA molecule is constructed from sequences of its four nitrogenous bases: adenine, thymine, guanine and cytosine. Since DNA is made up of two strands, the sequence of nitrogenous bases of one strand is complementary to the other
.
The complementarity of the bases is a characteristic of the nitrogenous bases in the nucleic acids to combine with their complementary base, which is the same as saying that purines complement with pyramidines.
- <em>Adenine is combined with Thymine A=T
</em>
- <em>Cytosine is complemented with Guanina C≡G
</em>
In this way, given a sequence on a DNA strand
:
<em> T-T-C-C-G-G-A-A</em>
The complementary strand will have this sequence:
<em> A-A-G-G-C-C-T-T</em>
Blood passes from the right ventricle to the <u>Pulmonary valve </u>and then the <u>Pulmonary artery</u> before reaching the lungs to pick up oxygen
<h3>Blood circulation procedure </h3>
When the blood enters the right ventricle it contracts and sends the blood through the Pulmonary valve before it reaches the Pulmonary artery which is passes the blood to the Lungs where it becomes oxygenated.
Hence we can conclude that Blood passes from the right ventricle to the <u>Pulmonary valve </u>and then the <u>Pulmonary artery</u> before reaching the lungs to pick up oxygen.

The smallest animal on Earth is one of the smallest hills, parasitic insects living in the body of bugs and beetles. The Latin name of this creation is Dicopomorpha echmepterygis.
Through suppression of the aconitase enzyme in the tricarboxylic acid cycle, aconitase, fluoroacetate is extremely hazardous to humans and other mammals.
'Lethal synthesis' of an isomer of fluor citrate is the cause. fluoroacetate is present in many different plant species, and ruminant animals can die from ingesting them consists of aconitase.
With the chemical formula FCH 2 CO 2 Na, sodium fluoroacetate is an organofluoride. The taste of this colorless salt, which is utilized as a metabolic toxin, is comparable to that of sodium chloride. Potassium and sodium salts are both derived from fluor acetic acid. In 1942, a report on the efficiency of sodium fluoroacetate as a rodenticide was published.

A viroid is an infectious piece of RNA without a capsid. A viroid is an infectious RNA molecule, which is similar to a virus, however, not quite the same thing. It's smaller than a virus and has no capsid. It is a coiled "naked" RNA molecule that can affect a cell. An example of human disease that is known to be caused by Viroid is hepatitis D.
