Why is myelin important in the nervous system? A. It allows signals to travel faster along axons because depolarization occurs only at myelinated locations. B. It allows signals to travel faster along axons because depolarization occurs only at nonmyelinated locations. C. It bundles the dendrites of adjacent neurons together. D. It increases capacitance across the cell membrane, which helps electrical signals to leave the axons. E. It traps neurotransmitters, increasing their concentrations in t...

RNA polymerase - ANSWER pries the two strands of DNA apart and joins the RNA nucleotides as they base-pair along the DNA templates promoter - ANSWER DNA sequence where RNA polymerase attaches and initiates transcription Synthesis of RNA transcript - ANSWER initiation; elongation; termination synthesis of RNA transcript initiation - ANSWER after RNA polymerase binds to the promoter, the DNA strands unwind, and the polymerase initiates RNA synthesis at the start point of the template stra...

A) Item (A) is greater than item (B). B) Item (A) is less than item (B). C) Item (A) is exactly or very approximately equal to item (B). D) Item (A) may stand...

alternative splicing - - Splicing of introns in a pre-mRNA that occurs in different ways - leads to different mRNAs that code for different proteins - Increases the diversity of proteins. dna transcription vs replication - - replication synthesizes new (daughter) DNA - transcription of DNA forms RNA does the structure of the DNA (nucleosomes) impact the ability of the RNA polymerase to transcribe genes? - - yes - tightly bound nucleosomes, it's harder to get to the DNA so there is less e...
