In which direction does rna synthesis proceed?
a. left to right
b. 3' to 5'
c. top to bottom
d. 5' to 3'

5' to 3'.

Explanation:

Transcription may be defined as the process of formation of RNA molecule from the template DNA with the help of enzymes and the various transcriptional factors.

The process of RNA synthesis occur in the 5' to 3' direction. The RNA polymerase reads in the 3' to 5' direction and leads to the synthesis in 5' to 3' direction. The transcription factors binds to the DNA promoter during RNA synthesis.

Thus, the correct answer is option (d).

4. the structure that conducts nerve impulses to and from the brain and serves as a reflex center for some sensory information without input from the brain is the:

spinal cord

5. the three-layered membrane that covers the brain and spinal cord and literally means membrane is called the:

meninges

6. the cord-like (string-like) structures that carry bio-electrical impulses from one part of the body to another are called

nerves

7. a group of nerve cell bodies that are found outside of the spinal cord and brain are referred to as:
