Which of the following macromolecules enter the nucleus of a eukaryotic cell through pores in the nuclear membrane? a. rRNAb. ri
Lina20 [59]

Answer:option C= mRNA

Explanation:

MACROMOLECULES are large molecules, such as protein, commonly created by the polymerization of smaller sub-units called monomers.

The NUCLEAR PORE is a protein-lined channel in the nuclear envelope. The NUCLEAR PORE regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.

mRNA is synthesized by DNA during a process known as the TRANSCRIPTION. After the synthesis, the new molecule moves from the nucleus to the cytoplasm. It passes through the nuclear membrane through a NUCLEAR PORE. Then, it will later join with a ribosome, which is just coming together from its two sub-units, one large and one small.

olya-2409 [2.1K]

Answer:

The correct option is 3. "At pH 6.5 the enyzme is 50% active"

Explanation:

For the titratable group to be protonated and cause the enzyme to be in the active state, it needs to have gained a hydrogen cation (H+). In order for that to happen, there must be enough hydrogen cations in the environment of the enzyme, and hence, an acidic pH is required in this case.

If you want to selectively label RNA being synthesized by cells(and not DNA) what radioactive compound would you add to the medi
romanna [79]

The right answer is E.

Uracil is a nitrogenous base (pyrimidine) specific for RNA. The nucleoide of uracil is called uridine and nucleotide is called uridine monophosphate or uridylate. In the DNA, there is thymine instead of uracil.

So if we mark the uracils, only the RNA will be marked. The DNA will not be given that there is no uracil in it.
