Transcription and splicing only occur in eukaryotic cells. Transcription and splicing both occur in the nucleus.

Explanation:

Transcription is mediated by RNA polymerases that transcribe the DNA into RNA. In eukaryotes, because coding regions (exons) on the DNA are occasionally interspersed with non-coding regions (introns), the formed RNA (usually called nascent RNA) need to be spliced to remove the non-coding parts. This forms a mature messenger-RNA. All this occurs in the nucleus of eukaryotic cells and only after the mature mRNA is formed is it exported to the cytosol for translation into proteins by ribosomes.

Splicing does not occur in prokaryotic cells because their genome is all composed of coding regions. Therefore transcription on DNA produces, directly, a mature mRNA.

Water-storing plants and deeply rooted shrubs are plants that characterize?
Nady [450]

Desert vegetation or xerophytes includes bushes with deep roots and plants that store water.

Another name for desert plant:

A plant species known as a xerophyte has evolved to live in environments with little fluid water, like a desert or an area surrounded by ice or frost in the Mountains or the Polar regions. Cacti, pineapples, and various Gymnosperm species are a few well-known instances of xerophytes.

  • Xerophytes have different adaptations to their morphological characters (morphology) and basic physiological functions (physiology) that allow them to store significant amounts of water and save it during dry seasons. During prolonged periods of severe dehydration or evaporation of their organs, some creatures can live, and at those times, their biochemical function may cease. Xeromorphic flora has such biological and morphological modifications.
