The answer is C. I hope this helps
Hairpin like structures are formed in both DNA and RNA but are common in RNA than in DNA. This is because DNA can be double stranded or single stranded while RNA is generally single stranded structure that can be double stranded only when it forms a hair pin like structure.
The features of hairpin structure in RNA are as follows:
1. This structure is a building block of many secondary structures of RNA.
2. The termination sequence during transcription also forms a hairpin loop like structure.
3. tRNA also forms a hairpin loop like structure and helps in the process of translation.
Answer:
The nervous system can cause the contraction of all three types of muscle tissue. For example, skeletal muscle contracts to move the skeleton, cardiac muscle is influenced as heart rate increases during exercise, and smooth muscle contracts as the digestive system moves food along the digestive tract.
The most compromised part of the body in the seated dental professional is the lumbar curve. The dental professional most of the time works seated or rotated at the hips. The human adult spine has normally three curves: the cervical (neck), the thoracic (middle back) and the lumbar (lower back). The lumbar curve plays a very important part in keeping the body's balance in an upright position. When working seated, the whole body tilts forward or twists, two situations that apply great pressure on the lower back.
