Definition
| The synthesis of an mRNA version of the instructions stored in DNA. |
|
|
Term
| ________ performs transcription by transcribing only one strand of DNA, called the _________. |
|
Definition
| RNA polymerase; template strand. |
|
|
Term
| What is the DNA strand not transcribed by RNA polymerase? |
|
Definition
| The non-template strand; sequence matches the sequence of RNA, but Us instead of Ts. |
|
|
Term
| What are the three phases of transcription? |
|
Definition
| Initiation, elongation, termination. |
|
|
Term
| RNA polymerase catalyzes the formation of ______________ between _____________. |
|
Definition
| Phosphodiester bonds; ribonucleotides. |
|
|
Term
| After DNA has been pulled apart and used as a template for creating a new mRNA, what happens to the DNA? |
|
Definition
| The hydrogen bonds that form between matching base pairs provide plenty of energy to pull the strands of DNA back together very quickly. |
|
|
Term
| Why is the new mRNA transcript constructed in the 5' to 3' direction? |
|
Definition
| The 3' OH is reactive and can form new bonds. |
|
|
Term

|
Definition
| Promoter-binding factors like sigma. |
