<span>The sugar arabinose in the agarose plate is needed to turn on the expression of the GFP (green flourescent protein) gene. The UV light is required to cause the GFP (green flourescent protein) protein within the bacteria to glow.</span>
Answer:
Guanine always pairs with Cytosine. :)
Explanation:
Water is generally regarded as universal solvent due to its ability to dissolve a wide range of compounds.
A water molecule has partial positive and negative charges on it thus, it is a polar compound.
- The binding rule for substances to dissolve one another is that they must be like one another.
- Polar solutes or substance only dissolves in polar solvents. Non-polar substances will dissolve in non-polar solvents.
- Water is polar and ionic substances are polar too.
- In water, the positive end of a salt is completely surrounded by water molecules and they hydrate it. The same analogy goes for the negative end.
- This is called hydration.
- The hydration complex keeps the salt dispersed in the water.
- This why water is able to dissolve a broad range of substances.

Answer:
The correct option is circular DNA molecules and small ribosomes
Explanation:
Prokaryotes can be described as organisms which are unicellular and lack membrane-bound organelles. They lack nucleus but usually have circular, double-stranded DNA present in them. Bacteria, which are prokaryotes, might even have extrachromosomal rings which are known as plasmids.
The ribosomes of the prokaryotes are smaller as compared to eukaryotes. Their smaller unit is 30S and larger unit is 50S. The smaller unit of eukaryotes are 40S and the larger units are 60S.
Answer:
The correct answer will be option- <em>Streptococcus pyogenes.</em>
Explanation:
M protein is an important virulence factor which is produced and expressed on the surface of <em>Streptococcus pyogenes.
</em>
This protein plays important role in the bacterial infection like adherence to epidermal keratinocytes, resistance to phagocytosis, invasion of epithelial cells and microcolony formation.
The M-protein is a α-helical coiled structure protein which consists of the four distinct regions (A–D) in which A-region in the N-terminal is highly variable.
Thus, option- <em>Streptococcus pyogenes</em> is the correct answer.
