All of the following are differences in transcription, RNA processing, and translation between prokaryotes and eukaryotes except
Mazyrski [523]

Answer:

the mRNA goes through extensive modifications such as addition of a poly tail and a 5' cap in eukaryotes but not in prokaryotes.

Differences:

- the promoters in prokaryotes have a -35 and -10 box while in eukaryotes they are variable but have a TATA box from  

- the transcription initiation site there is a single RNA polymerase in prokaryotes while eukaryotes have multiple RNA polymerases

- the sigma factor associates with the promoter region in prokaryotes but in eukaryotes there are many basal transcription factors

Explanation:

Ribosomal and transfer RNAs are processed both in prokaryotic and eukaryotic organisms. However, mRNA is only processed in eukaryotes. In eukaryotic cells, mRNA processing involves:

1. Capping at the 5' end. This process has several functions including regulation of nuclear export, prevention of eukaryotic mRNA degradation and promotion of translation.

2. Splicing in order to remove introns and conserve coding exons. Splicing helps to increase the diversity of the eukaryotic mRNAs (and therefore eukaryotic proteins)

3. Polyadenylation by the addition of a poly(A) tail at the 3' end. The poly(A) tail makes the eukaryotic mRNA molecule more stable and also prevents its degradation by exonucleases.

Habitat destruction, and thus habitat fragmentation, is the major cause of declining biodiversity; the second major cause is ___
alekssr [168]

Habitat destruction, and thus habitat fragmentation, is the major cause of declining biodiversity; the second major cause is <u>Invasive Species</u>.

The process by which a natural ecosystem can no longer support its native species is known as habitat destruction. Reduced biodiversity and species abundance result from the displacement or death of the creatures that once occupied the area. The loss of biodiversity is mostly caused by habitat degradation.

An imported organism that overpopulates and damages its new habitat is referred to as an invasive species. Even though the majority of imported species are neutral or helpful to other species, invasive species have a negative impact on habitats and bioregions, harming their ecology, the environment, and/or their economy.

The most frequent methods for invasive plants, animals, microorganisms, and other species to spread to new ecosystems are thought to be human activities like those involved in international trade and the pet trade.
