That would be B. 5’ and 3’ ends.

The side that has the 3’ of the deoxyribose is the 3’ end

The side that has the 5’ of the deoxyribose which is connected to a phosphate group is the 5’ end.

Sergio039 [100]

Answer:

Both studies support the concept that species operate within a narrow optimum temperature range and are coupled to enzymatic activity.

Explanation:

The studies shown in the question above started from the same concept to establish the scientific experiment and had the same objective related to the investigation as temperature changes in the environment where these organisms live influences the enzymatic activity and, therefore, the functioning of their organism, being able to including modifying the environment around them. In summary, we can say that the studies sought to support the concept that species operate within a narrow range of optimal temperature and are coupled with enzymatic activity.

A researcher is carrying out an experiment where she labels a protein with a fluorescent tag (so she can visualize its location
melisa1 [442]

Answer:

The protein likely travels through a common lumen shared by thylakoid membranes and grana, and cannot easily diffuse through the thylakoid membrane.

Explanation:

There is a lot of scientific research in which a specific molecule can be labeled with some fluorescent marker (usually carbon 14). This type of marking allows the researcher to make observations about the movement of these molecules, as you can see in the question above. About the research shown in the question, the researcher realized that the protein labeled with the fluorescent marker moved between the grana and was always in the lumen, so she can conclude that the selocomovement protein moved through the lumen that is shared between the tilacoid membranes and the grana.

What is the approximate percentage of guanine in the DNA genome of E. coli?
Nadya [2.5K]

Answer:

25%

Explanation:

<em>The approximate proportion of G + C content in the genome of E. coli has been reported to be 50%. According to Chargaff's rule, the amount of guanine in any DNA must be approximately equal to the amount of cytosine. </em>Hence,

if G + C = 50 and G = C,

then

G = C = 25

Therefore, the approximate percentage of guanine in the genome of <em>E. coli </em>would be 25.
