|
Transcription |
Makes mRNA from DNA in the nucleus and then transports the mRNA to the Ribosome |
|
|
Translation |
Uses the code on the mRNA to create a protein |
|
|
Transcription Step 1 |
Cellular conditions and the promoter sequence activate a gene. (3') TATAAA (5'). |
|
|
Transcription Step 2 |
The RAN Polymerase finds the start triplet. (3') TAC (5') |
|
|
Transcription Step 3 |
Using the establishment triplet reading frames, find a stop triplet. (3') ATC (5'), (3') ATT (5') OR (3') ACT (5') |
|
|
Transcription Step 4 |
RNA Polymerase builds the pre-mRNA based on the gene identified by the start and stop triplets. |
|
|
Transcription step 5 |
mRNA is separated from DNA. DNA is recombined. |
|
|
Transcription Step 6 |
Editing... A. Remove intron(s) from pre-mRNA. keep exons B. Add a GTP Cap at the 5' end of thr mRNA C. Add a poly-A-tail at the 3' end of the mRNA |
|
|
Transcription Step 7 |
mRNA leaves the nucleus through nuclear pores. |
|
|
Where is information Located? |
The nucleus. |
|
|
In each somatic (non-sex) cell, humans have... |
1 complete copy of our genome 23 different types of chromosomes with 2 copies of each type for a total of 46 chromosomes. There are approximately 20,000-25,000 genes |
|
|
DNA is... |
Double stranded Sugar = Deoxyribose Stuck in the nucleus Inherited Has guanine, adenine, cytosine and thymine |
|
|
RNA is... |
Single stranded Sugar = Ribosome Made in the nucleus but it can leave. Made from DNA Has cytosine, uracil, guanine, and adenine |
