A sudden and violent movement of the ground sometimes causing great destruction as a result of movements within the earths crust or volcanic action.
Answer:
Transcription and RNA processing (splicing)
Explanation:
Although Howard is almost right, the DNA sequence does not precisely relate to the protein sequence. First of all, the DNA is transcribed to an primary mRNA molecule. Bur before the mRNA is ready to be translated into an amino acid sequence, it must be processed into a mature mRNA.
This includes adding a 3' poly A tail, and a 5' cap, and importantly for this question, splicing.
Splicing is the removal of non protein coding intermediate sequences called introns from the protein coding regions (exons) of a primary mRNA. This means that lots of the DNA sequence is not dictated by the final protein, as many of the intervening sequences have been removed by splicing.
Erosion is brought about by the forces of nature or human activity: water, wind, earthquakes, mining, quarrying, etc. In the desert, there is very little water that can cause weathering or erosion, so the most probable answer is wind or maybe even animal activity.
Mass movement, which is sometimes called <em>waste movement</em> or <em>slope movement, </em>is defined as the large movement of rock, soil and debris downward due to the force of gravity.
<h3>Factors affecting mass movement
</h3>
1. Slope
- Gravity provides the energy to move the materials.
- Rapid movements (e.g. landslide, slumping) etc.
2. Water
- Rainwater acts as a lubricant to weathered materials.
- Rainwater adds weight to weathered materials.
3. Rock structure
- Joints dipping downslope usually assists landslides, rockfalls, rockslide etc
4. Vegetation
- Lack of vegetation cover to hold the loose particles.
5. Vibrations
- Earthquakes.
- Construction processes and mining operations.
