Answer:
E. Gene is amplified by multiplication of cloning host
Explanation:
PCR is a very powerful technique that can help us to amplify exponentially one gene from a very small sample of DNA.
As seen in the attached image, the process begins with a single DNA molecule, for the first cycle, that DNA molecule denaturalizes into two strands, the primers bind to their complementary sides and then the DNA polymerase builds the new DNA strands. The number of copies of the gene that can be obtained with each cycle are 2ⁿ copies, where n is the cycle number.
Answer:
a state of sustained partial contraction
Explanation:
Simply said, muscle tone means that there is a sustained tension in a muscle wile in a determinate posture. The muscle tone enable us to mantaing our bodies in a posture fit for resting or for also working, like sitting, being stand up or in a couch or sleeping. The changes in the muscle tones make us able to move. So contractions will follow depending what activity we are engaged on, as a continous and passive partial contraction of muscles change following changes in direction.
Muscle tones have contractions that do not produce enough tension to move, buy they keep it tense and firm.
Thererefore the tension is balanced and resting muscle tone balances bones and joints.
See below :)
In physiology, medicine, and anatomy, muscle tone (residual muscle tension or tonus) is the continuous and passive partial contraction of the muscles, or the muscle's resistance to passive stretch during resting state. It helps to maintain posture and declines during REM sleep.
