What that determines if a cell is eukaryotic. *

To determine whether a cell is a eukaryotic or
prokaryotic cell, one can observe certain features.
If the cell in the question possesses a well-defined
or definite nucleus and have membrane-bound
organelles such as mitochondria, chloroplasts,
Golgi apparatus, endoplasmic reticulum, the cell is
eukaryotic. If the cell has nucleoid or indefinite
nucleus and without membrane-bound cell
organelles, the cell is prokaryotic. If ribosomes in
a cell are the 80S (S=Svedberg units) type, the cell
is eukaryotic and if ribosomes are 70S type then it
is prokaryotic.

There’s not any answer choices, but eukaryotic cells possess a clearly defined nucleus. they also have more organelles

Now can you predict nucleotide quantities in a hypothetical scenario with more than four different types of nucleotides? An alie

den301095 [7]

Answer:

16% is G

12% is T

12%is A

22% is X

Explanation:

Given that each nucleotide is complimentary to another nucleotide, there cannot be more of one than the other. For example, C bonds to G, so there cannot be more C than G, because there would be nothing for it to bond to.

So if there is approximately 16% of the genome composed of C, that would mean that approximately 16% is composed of G (for it to bond to).

The same logic can be used to determine the amount of nucleotide X is present. If Y binds to X, and approximately 22% is composed of nucleotide Y, then the same percentage can be given to nucleotide X, and say the amount of X is 22%.

Now all of the nucleotides have to add up to 100%, so:

A + T + G + C + X + Y = 100%

A + T + (16%) + (16%) + (22%) + (22%) = 100%

A + T = 24%

Given that A binds to T, they must be equal to each other, hence we can say that the concentration of A, equals the concentration of T.

Therefore, the concentration of A is 12%, and the concentration of T is also 12%.

Which of the following is not required for the proper use of molecular beacons?

arlik [135]

Answer:

b. Detachment of a separate hybridized probe molecule from the template DNA

Explanation:

Molecular beacons are a type of genetic probe that enables the hybridization of oligonucleotides. These molecules have a flourishing component that binds to a nucleotide sequence and allows the identification of this nucleotide sequence in DNA or RNA without the release of radioactivity. For the use of these molecular beacons to be possible, one needs complementarity between the model DNA and the probe sequence, illumination of the hybridized beacon to detect fluorescence and proximity-based quenching of the fluorophore prior to beacon hybridization.

True or False: Photosynthesis and

Reil [10]

Answer: I believe this is FALSE.

Explanation: I say this because, although photosynthesis is required to keep the plants alive which causes respiration. It is not objectively needed in the cycle, and it isn't caused by animals.

I hope this helps :D.

Distinguish between a Longitudinal study and Cross-sectional study in biostatistics

nydimaria [60]

Answer:

missing - biostatics

Explanation:

Longitudinal studies differ from one-off, or cross-sectional, studies. The main difference is that cross-sectional studies interview a fresh sample of people each time they are carried out, whereas longitudinal studies follow the same sample of people over time.

hope this helps :)
