<span>the race to determine how these pieces fit together in a three-dimensional structure was won by James Watson and Francis Crick at the Cavendish Laboratory in Cambridge, England. They showed that alternating deoxyribose and phosphate molecules form the twisted uprights of the DNA ladder. The rungs of the ladder are formed by complementary pairs of nitrogen bases — A always paired with T and G always paired with C so they form a ladder like shape</span>

A DNA molecule is like a ladder because there are two sides (the sugar-phosphate backbones of the two strands) and rungs (each rung being a pair of complementary bases). Twisted, because the molecule is twined in a coil called a helix - or rather, a double helix because there are two strands.

What is the main difference between bacteria and humans that gives Sulfa drugs their antibacterial properties? Group of answer c
sertanlavr [38]

Answer:

Human cells can readily absorb folic acid; bacteria cells cannot.

Explanation:

Bacterial cells cannot absorb folic acid and synthesize it. On the other hand, humans do not synthesize folic acid in their cells. They rather obtain it from the diet. Sulfa drugs, for example, sulfanilamide resemble p-aminobenzoate (PABA). PABA is a molecule that is used as a substrate in the synthesis of the coenzyme folic acid. The sulfa drugs serve as competitive inhibitors and compete with PABA for the catalytic site of an enzyme involved in the folic acid synthesis. This prevents the synthesis of folic acid in bacterial cells and thereby, inhibits bacterial growth.

Describe a virus and how it's different from a cell?
lana [24]

Answer:  how a virus differs from a cell...

It doesn’t contain any kind of cytoplasm, cell wall, cell membrane, ribosome or mitochondrion.

It doesn’t have any sort of metabolic enzyme of its own. So, no nutrition system is seen.

It can’t reproduce itself, without any help of the host living cell.

It can be crystallized, centrifuged or diffused.

It doesn’t have any sort of somatic development.

Chemically, its just a fusion of protein and nucleic acid. So, this characters differ a Virus from a living cell.
