Central Dogma
What is gene expression?
Transcription and translation of a specific gene
What is the enzyme that mediates DNA replication?
DNA polymerase
What are exons?
transcribed regions "coding regions"
What is the final product made in transcription?
proteins
What happens in elongation?
Amino acids are sequentially joined by peptide bond in an order specified by the arrangement of codons in mRNA.
Can you go from protein to DNA?
No
DNA helicase builds hydrogen bonds in the DNA true or false?
False, it breaks the hydrogen bonds.
A promoter is used to terminate transcription. True of False?
False
What is the template for translation?
mRNA
What is the monomer for protein synthesis?
Amino acids
RNA to a protein is called?
Translation
Parent strands of DNA is read from what prime to what prime end?
3' to 5'
What is the 5' cap for?
Facilitates binding to a ribosome and prevents digestion by ribonucleases
What is the first step in translation & what does it do?
Initiation
Where mRNA is bound to the ribosome and positioned right to get ready for translation.
mRNA forms from what prime end to what prime end?
5' to 3'
DNA to RNA is called?
Transcription
what do single stranded binding proteins do?
bind, stabilize, and keep DNA separated
What is the poly A tail for?
It assists in export from the nucleus to the stability of the mRNA.
In termination the tRNA can recognize a stop codon. True or False?
False, stop codons are recognized.
When is exam 4 due?
December 3rd
What is central dogma?
The flow of of genetic information in a biological system.
Primase is not an RNA polymerase true or false?
False, it is.
Do introns code for anything? Yes or No.
No
In elongation there is only one step? True or false.
False, there is many steps
What days are the final reviews?
Friday December 3rd 11-12pm and Monday December 6th 4-5pm
