The relative hybrid duplex structure of DNA and RNA is greatly influenced by primary sequence composition. The primary sequence

dictates duplex structure and stability, giving DNA a B-type helix, RNA an A-type helix and DNA:RNA a mixed A:B type helix as illustrated below. Based on the structural and thermodynamic study of DNA and RNA duplexes, rationalize which type of hybrid duplexes form the most stable structures and describe experimental methods that can be used to characterize i. duplex stability and ii. duplex structure. Relative thermodynamic stability of DNA, RNA, and DNA:RNA hybrid duplexes: relationship with base composition and structure.
a) dsRNA.
b) dsDNA.
c) dNA-RNA.

When joints are not regularly moved through their entire range of motion, muscles and ligaments eventually _____. a. shorten b.
zhuklara [117]

Answer:

a. shorten

Explanation:

Inability or failure for joints to move through their entire range of motion is caused by constrictions. These constrictions often results when the excess adipose tissues that surrounds the muscles and ligaments are not in required adequate proportion. These constrictions can be caused by ageing, fatigue, muscular diseases etc. As a result of these constriction in the joints, let say for example, the knee joint, the muscle and ligaments tends to shorten in length.

Which structure is at work when the body deals with reflex actions?
Ne4ueva [31]

Answer:

spinal cord

Explanation:

Reflex actions are the involuntary action of the body in response to a signal or stimulus. The reflex action of body is controlled by spinal cord.

Reflex arc acts as a neural pathways that transmit impulse to the brain via spinal cord. Sensory neurons pass through synapse in the spinal cord which activate spinal motor neuron to act immediately without any delay.

Immediate taking off hand from hot oven is an example of reflex action, which is regulated by spinal cord.  

Hence, the correct option is spinal cord.
