Rna splicing - Samenvattingen, Aantekeningen en Examens

What is the DNA -> RNA process? - RNA polymerase I creates a transcript. This is primary RNA with 5' cap and 3' with poly(a) site. Maturation of RNA includes cleaving at the poly(a) site and RNA splicing of introns to leave matureRNA. What is the mRNA to protein process? - Codons run through ribosome in 3 base pairs. A corresponding tRNA recognises 3 base pair and brings with it conjugate bases and an AA. This adds the relevant AA for every 3 base pair, creating a polypeptide. What is...

Nucleic Acid grows by attachment of 5' phosphate group of the incoming nucleotide to the 3'hydroxyl group of the last nucleotide double stranded DNA most energetically favorable state for DNA Purines double-ring structure Adenine (A) + Guanine (G) Pyrimidine single-ring structure Uracil (U)+ Cytosine Messenger RNA (mRNA) -template for all protein synthesis -encode all information necessary to produce proteins Heterogeneous nuclear RNA primary product o...

TEST 1 BIO 1A03 QUESTIONS AND ANSWERS 100% PASS Central Dogma theory that states that, in cells, information only flows from DNA to RNA to proteins what enzyme is used to transcribe DNA and describe the process RNA polymerase attaches to specific promoter regions its these promoter regions which identifies the starting point, describe the DNA and RNA directionality and how the direction followed by RNA polymerase the 5' end has the 5'phosphate on a nucleotide the other end is the 3' OH grou...

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 concentratio...
