A deficiency of dopamine is responsible for the signs and symptoms of Parkinson's disease.

Parkinson's disease is characterized by gradual degeneration of neurons in a section of the brain. In normal conditions, these neurons release a chemical substance known as dopamine which is important for the brain.

Dopamine is a neurotransmitter which facilitates communication amongst different parts of the brain that is responsible for smooth muscle activity and proper nerve operation.

Parkinson’s disease is a disorder generally associated with uncontrollable movements like tremors, rigidity as well as problems linked with maintaining body balance and coordination. Symptoms generally develop slowly and intensify over the period.

People may experience trouble in walking and talking with  the advancement of the disease. The patients may also exhibit mental as well as behavioral alterations, sleep trouble, depression, memory problems and lethargy.

Describe the steps in transcription that require complementary base pairing.
nalin [4]

Answer:

Explanation:

Transcription takes place in nucleus in the presence of the enzyme RNA polymerase.

During transcription, the code present in DNA gets transcribed into the code in mRNA.  (messenger RNA)

RNA even though is a single stranded shows base pairing.

The pre-mRNA gets created from the DNA.

DNA has two strands, one of these strands acts as coding and another non coding strand.

The DNA shows base pairing with AGTC.   [A-Adenine, G- Guanine, T-Thymine and C- Cytosine]

Whereas mRNA base pairing with AGUC.  [ U- Uracil ]

Here in mRNA, instead of thymine, uracil gets paired.

According to base pairing of coding strand/sense strand of DNA, complementary bases pairs in 5'---->3' direction in mRNA.

The mRNA created looks exactly like the non-coding strand/sense strand of DNA except instead of thymine, uracil gets replaced.

The pre-RNA undergoes splicing, capping and tailing to form mature mRNA.

When you view the pendulum’s swing, it shows that at the very top of the swing KE = 0. What does that tell you about the pendulu
Harlamova29_29 [7]
At the very top of the swing the velocity=0. If the velocity is 0 then the kinetic energy is 0 as well because kinetic energy is the energy of movement.
