Introns must be removed prior to translation of the mRNA. In addition, eukaryotic transcripts (mRNA) have to undergo two more st
Ivan

Eukaryotic transcripts (mRNA) have to undergo capping and splicing before it can be translated.

<h3>RNA processing:</h3>

1. An RNA transcript is first produced in a eukaryotic cell as a pre-mRNA, which needs to be converted into a messenger RNA (mRNA).

2. The RNA transcript is given a 5' cap at the start and a 3' poly-A tail at the end.

3. The process of splicing involves cutting out some RNA transcript segments (introns), then joining the remaining segments (exons) back together.

4. Some genes have the ability to alternate splices, which produces various mature mRNA molecules from the same beginning transcript.

The introns not only do not contain the information necessary to construct a protein, but they also need to be cut off in order for the mRNA to create a protein with the correct sequence. An mRNA with extra "junk" in it will be created if the spliceosome fails to remove an intron, and the translation process will result in the production of the incorrect protein.

Based on the phylogenetic tree below, which groups of plants evolved most recently?
xeze [42]

Answer: The correct answer is- gymnosperms and angiosperms.

Phylogenetic tree is a diagrammatic representation that depicts the evolutionary relationship among different group of species. In other words, it is used to interpret the relatedness among different species and how they have descended from a common ancestor.

The tips in the phylogenetic tree represents the taxon ( or particular group of species) that are descended.

In the given tree, gymnosperms and angiosperms have evolved most recently because they correspond to the most recent branches having the immediate common ancestor at the topmost level as compared to the immediate common ancestor of other taxon.

Thus, gymnosperms and angiosperms is the right answer.
