Replicaton
Must be very accurate and fast in order to work.
What is Replication?
Translation involves “decoding” a messenger RNA and using its information to build this.
What is a polypeptide (amino acid chain)
these are the steps of translation.
What are initiation, elongation, and termination?
These are the fragments within the lagging strand of DNA.
What is Okazaki Fragments?
What are the 6 proteins required for DNA replication?
What is Helicase, Single Strand Binding Protein, Topoisomerase, polymerase, primate, Ligase?
This type of replication is bidirectional and uses circular DNA.
What is Theta Replication?
During this stage of Translation, the ribosome gets together with the mRNA and the first tRNA so translation can begin.
What is initiation
During initiation RNA Polymerase binds to this sequence of DNA found near the beginning of a gene.
What is the promoter?
During the termination stage of translation, stop codons are recognized by these proteins.
What are release factors?
These three key ingredients are required for translation to begin.
What is a ribosome, an mRNA, and a tRNA?
This typeof replication is single directional, makes only one copy at a time, and all free floating strands replicate.
What is Rolling- Circle Replication?
During this stage of Translation, amino acids are brought to the ribosome by tRNAs and linked together to form a chain.
What is elongation
During Elongation the RNA transcript carries the same information as the non- template strand of DNA, but it contains this base instead of thymine.
What is Uracil?
This step in gene expression involves copying a genes DNA sequence to make an RNA molecule.
What is Transcription?
DNA is synthesized in this direction.
What is 5 prime to 3 prime?
This type of replication is slow in speed and hs multiple sites of origin.
What is Linear Eukaryotic Replication?
During this stage of Translation, the finished polypeptide is released to perform its job within the cell.
What is termination
This is a substrate for transcription, and is like a landing pad for a helicopter. It is a stretch of DNA that codes for RNA.
What is the transcription unit?
This key molecule is responsible for synthesizing DNA.
What is DNA polymerase?
This enzyme makes an RNA primer that provides a 3 prime end for a DNA polymerase to work on.
What is Primase?
1. A template consisting of single stranded DNA
2. Raw substrates are assembled
3. Enzymes are present
What are the requirements for replication?
This codon is a “start” signal to kick off Translation.
What is “AUG”
This type of terminator does not need the Rho protein.
This specific enzyme facilitates the joining of DNA strands together by catalyzing the formation of phosphodiester bonds.
What is DNA Ligase?
The term used in DNA replication referring to the process of each strand in the double helix acting as a template for synthesis of a new complimentary strand.
What is Semiconservate?
