Total nucleic acids are extracted from a culture of yeast cells and are then mixed with resin beads to which the polynucleotide

5'-TTTTTTTTTTTTTTTTTTTTTTTTT-3'
has been covalently attached. After a short incubation, the beads are then extracted from the mixture. When you analyse the cellular nucleic acids that have stuck to the beads, what will be most abundant?
mRNA because it is the only type of RNA that is polyadenylated and the poly (A) tail would be able to base pair with the strands of poly(T) on the beads and thus stick to them. DNA would not be found in the sample, as the poly (A) tail is not encoded int he DNA and long runs of T are rare in DNA.

The question is incomplete as it does not have the options which are:

(a)DNA (b)tRNA (c)rRNA (d)mRNA

Answer:

Option-mRNA

Explanation:

The mRNA is synthesized from the DNA and which is also a type of nucleic acid. When the nucleic acid is extracted from the yeasts and then mixed with the resin beads to which the polynucleotide with thymine base oar is attached.

The mRNA will bind to the resin bead as the mRNA after synthesis undergoes modification and attaches poly A tail to the end of the mRNA at 3' end.

This poly-A tail has adenine which easily binds to the thymine and thus mRNA easily attaches to the resin bead.

Thus, mRNA is correct.

Alexxandr [17]

"Eukaryote" roughly translates as "truly nucleated" and refers to organisms with a membrane-bound nucleus.

Such membrane-bound organelles are thought to have arisen via the invagination of the cell's own plasma membrane.

Other organelles such as the mitochondria and the chloroplast are believed to have once existed as separate organisms, but which were engulfed by other cells, forming a symbiotic relationship.

3. Does your skate park playground ramp design support the law of conservation of energy? Use
nlexa [21]

Skate park is a good example that maintains the law of conservation as skater neither creates nor destroys energy.

Explanation:

As per the law of energy conservation, energy cannot be created nor can be destroyed but it’s form can definitely be changed. This theory can be well justified by the example of skate park playground. According to the rules of this law a skater can never go high more than 2 meters on the ramp’s other side because it has that gravitational energy potential.  

With every drop of the skater on the ramp the potential energy of the skater changes into kinetic energy. This two sides of the law justifies the fact that skate playground should be designed in such a way that it supports the law of conservation of energy.
