The DNA polymerase reaction occurs in the ________ as incoming nucleotides are added to ________ end(s) of the growing DNA chain
nasty-shy [4]

Answer:

5' → 3' direction or 3'- hydroxyl

Explanation:

DNA replication takes place in the direction from 5' to 3' prime because the template strand is read along 3' to 5' direction and complementary strand is made in opposite direction of template strand during replication.

The new nucleotide that is added on the free 3' hydroxyl end of ribose sugar by phosphodiester bond in the new complementary strand. 3' to 5' phosphodiester linkage makes the backbone of polynucleotide.

In DNA synthesis adenine pairs with thymine with two hydrogen bonds and guanine pairs with cytosine with three hydrogen bonds. So the correct answer is 5' → 3' direction or 3'- hydroxyl.

What is the thin layer of endothelial tissue that lines the inner surface of the heart and the valves called
serious [3.7K]

Answer:

Endocardium

Explanation:

The endocardium makes the innermost lining of the wall of the heart. It is present over the thin layer of connective tissue. The function of the endocardium is to provide a smooth lining for the chambers of the heart. The valves present in the heart also have endocardium. The dense connective tissue of the heart valves is covered by endocardium.

The presence of the smooth endocardium made up of endothelium reduces the surface friction as blood passes through the heart. The endocardium of heart chambers is continuous with the endothelial lining of the large blood vessels that are attached to the heart.

What are Genes that produce alternative expressions of a trait called
Brrunno [24]
The answer should be allele(s).

Alleles are alternative forms of genes. For example in eye color, there is brown eye allele that produces brown eyes or blue eye alleles that produces blue eyes. 

However, note that there may be dominant or recessive alleles. Dominant alleles are always expressed, meanwhile, recessive allele is only expressed when there is no dominant allele existing. 

An example is let say brown eye allele is dominant and blue eye allele is recessive. The eye gene is controlled by 2 alleles. If I had one brown eye allele and 1 blue, my eyes will be brown, because brown eye allele is dominant.
