Question | Answer |
---|---|
Central Dogma Model | DNA --> Transcription --> RNA --> Translation --> Protein |
What is a gene? | A unit of heredity that is transferred from a parent to an offspring and is held to determine some characteristic from the parents. |
What is Gene Expression? | It converts the information in a gene into a specific polypeptide of specialized RNA molecule in the proper cell. |
Define Transcription | Transfers the information stored in the coding strand of a gene to a mRNA molecule |
What specific information is stored in the DNA? | Genetic codes and nucleotide sequences |
What is a promoter? | a sequence in the nucleotide sequence to signal the DNA polymerase to start unwinding. |
What is the TATA box? | Found in the promoter region. Indicates the point at which a genetic sequence can be read and decoded. |
What role does RNA Polymerase II perform in the transcription of a protein coding gene? | Unwinds the double helix and synthesizes a mRNA molecule complementary to the template strand. |
Which molecule is synthesized by RNA Polyermase II? | mRNA |
What are codons? What do they contain? | THREE nucleotide sequence in mRNA that codes for a specific amino acid, a translation start site or a translation stop site. |
What are triplets? | Three bases code for one amino acid. |
