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:
1. Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups.
2. The DNA double helix. The two sides are the sugar-phosphate backbones, composed of alternating phosphate groups and deoxyribose sugars. The nitrogenous bases face the center of the double helix.
3. A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
4. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
5. In genetics, the term junk DNA refers to regions of DNA that are non-coding. Some of this noncoding DNA is used to produce noncoding RNA components such as transfer RNA, regulatory RNA and ribosomal RNA

Answer:
A scientist who studies water and its properties is a hydrologist.
Explanation:
A hydrologist is a scientist linked to the study of water, both surface and underground, detecting cleanliness or contamination and proposing alternatives for its cleaning and conservation.
A hydrologist's research on the properties of water, its location, distribution and circulation contributes to the maintenance of the environment.
The other options are not correct because:
<em> A) </em><u><em>Entomologist
</em></u><em>: a scientist who studies insects.</em>
<em> B) </em><u><em>Chemist
</em></u><em>: a professional who studies the elements and chemical compounds and their properties.</em>
<em> D) </em><u><em>Oceanographer</em></u><em>
: study both oceans and seas, and their relationship with the environment, the atmosphere and the land.</em>
<em> E) </em><u><em>Toxicologist</em></u><em>: study the effects of toxic or harmful substances on living beings and the environment.</em>
