Central Dogma DNA → RNA → Protein Purines - which bases? - how many rings? Brainpower Read More 0:14 / 0:15 Pyrimidines - which bases? - how many rings? Remember: "Pyrimidine" has a "y" in it; so does "cytosine" and "thymine." Phosphodiester Bond Joins one nucleotide to the next; between the 3rd C of one ribose and the 5th C of the other to create the sugar-phosphate backbone Directionality of DNA (convention) 5' → 3' (but strands are ant...

BIO 111 TAMU Fletcher Exam 3 Already Graded A Friedrich Miescher discovered DNA in 1869 But did not know (Isolated phosphate) rich acidic compounds Frederick Griffith Discovered transformation during an experiment that involved injecting mice with smooth S cells, rough R cells, heat-killed S cells, and heat-killed S cells with living R cells. Avery, MacLeod, McCarty Identified the heritable substance as DNA Used test tubes- vitro Hershey and Chase performed experiments showing that DNA is the...

Describe the process of transcription. What are the starting molecules and the end products? - ️️Transcription is the manufacture of a strand of RNA complementary to a strand of DNA. In initiation, RNA polymerase binds to a promoter region on the DNA strand. RNA synthesis occurs during the elongation phase as RNA nucleotides are added to the growing RNA polynucleotide. When the RNA polymerase reaches the terminator region of the gene, elongation stops and the polymerase and new RNA molecule ...

MICR 2123 Exam 2 Questions with All Answers Revised and Updated Helicase - Answer-An enzyme in DNA replication that "unzips" the two strand by breaking the H bonds. Primase - Answer-An enzyme in DNA replication that lays down a short stretch of complementary RNA. DNA Polymerase - Answer-The star enzyme of DNA replication. Adds the nucleotides to the grown chain, using information from the original strand. Rnase H - Answer-An enzyme in DNA replication that removes the RNA primers....

The polarity of doubled-stranded DNA arises from A. negative charges on the backbone phosphates B. the presence of 5' phosphates on one end and 3' hydroxyls on the other C. base pairing D. the sequence of bases, which is strand-specific - Answer- B A missense mutation is one in which A.the altered codon codes for the same amino acid. B.the altered codon codes for a different amino acid. C.the mutant protein is shorter than normal. D.insertion or deletion results in a shift in t...

Gene Expression - Process by which DNA directs protein synthesis; transcription and translation Transcription - Synthesis of RNA under DNA direction; Produces mRNA; use same language Translation - Synthesis of polypeptide under RNA direction; Nucleic acids and amino acids use different language, Ribosomes are site of translation Triplet code - Series of three-nucleotides (make amino acids) Template strand - Provides template for RNA transcription mRNA base triplets - Codons Direction codo...

WGU Biochemistry OA Review Questions And Answers 2022. The polymerase chain reaction is a tool used to study protein structure. True False Ans - False Feedback PCR is a tool used to amplify a specific segment of DNA. What color is the primer in the following diagram? Red Purple Blue Ans - Red Feedback Recall from the section on DNA replication that DNA polymerase needs a primer to begin DNA synthesis. This requirement means the primers will direct the DNA polymerase to only synthesi...
