Vikki [24]

Siendo así, el proceso de fotosíntesis es más importante de lo que parece. Gracias a la luz, las plantas son capaces de captar dióxido de carbono y expulsar oxígeno a lo largo del día, mientras que por las noches sucede al revés: absorben oxígeno y liberan dióxido de carbono.

Expression of a cloned eukaryotic gene in a bacterial cell involves many challenges. The use of mRNA and reverse transcriptase i
damaskus [11]

The use of mRNA and reverse transcriptase in this case is part of a strategy to solve the problem of post-transcriptional processing. So the correct option is A.

<h3>What is post-transcriptional processing? </h3><h3> </h3>

The process of transcription results in the formation of a heterologous nuclear RNA (hnRNA) or a precursor RNA (PreRNA). This undergoes post-transcriptional processing to form mRNA. Following are the steps -

  1. Splicing - it removes the non-coding introns so that only coding regions called exons remain.
  2. Capping - a 5'-methylguanosine triphosphate is attached at the 5' end of the RNA.
  3. Tailing - About 200 polyadenylate residues attach at the 3' end of the RNA.

These processes result in the formation of mRNA.

Therefore the correct option is A.

Prokaryotic cells are much smaller than eukaryotic cells. What advantages might small cell size confer on a cell
Snezhnost [94]

Answer:

At 0.1 to 5.0 μm in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10 to 100 μm ([link]). The small size of prokaryotes allows ions and organic molecules that enter them to quickly diffuse to other parts of the cell
