Replication, Transcription, Translation, and Bioinformatics
| Question | Answer |
|---|---|
| The process of taking a DNA template and making a complementary RNA molecule is called? | Transcription |
| ____RNA polymerase plus sigma factor together are called ______ | Core; holoenzyme |
| A consensus sequence of any genetic element is | the sequence with the most likely base/bases at each position. |
| DNA-dependent____ polymerase makes a copy of DNA that is then used for translation. The process carried out by this enzyme is called______. | RNA; transcription |
| A consensus sequence of any genetic element is | the sequence with the most likely base (or bases) at each position |
| Molecules of sRNA do not encode proteins but are used to____ the stability or translation of specific mRNAs into proteins. | regulate |
| In the absence of Rho, what can bring about transcription termination? | GC-rich region near the 3' terminus followed by four to eight uridines |
| The unusual bases found in tRNA are poor substrates for | RNases |
| Different _____ can bind simultaneously to the start of each gene within a polygenic mRNA. | ribosomes |
| What is a codon? | A set of three nucleotides that encodes a particular amino acid |
| What is sigma factors? | A protein needed to bind RNA polymerase for the initiation of transcription in bacteria. No sigma factors, no transcription. |
| What is a genome? | All of the genetic information that defined an organism. |
| What are Introns and Pseudogens?? | They are noncoding DNA sequences that make up a large portion of eukaryotic chromosomes. |
| The average half life for mRNA in a typical bacterium such as E.coli is | 1-3 minutes |
| The significance of the Shine-Dalgarno sequence is that it is the site where______________________. | a ribosome binds so that it can initiate translation |
| The typical bacterial ribosomes is composed of | two subunits made of three RNAs and at least 50 proteins. |
| The term "____" is used to describe movement of a protein from one compartment to another. | translocation |
| SRP stands for_____, and it plays a role in ________. | signal recognition particle; secretion |
| Signal sequences are found where? | at the N-terminal end of a protein |
| Genes that have arisen from a duplication within a species and have evolved to carry out different functions are referred to as? | paralogs |
| RNA; transcription | |
| Molecules of sRNA do not encode proteins but are used to______the stability or translation of specific mRNAs into proteins | Regulate |
| The average half-life for mRNA in a typical bacterium such as E.coli is | 1-3 minutes |
| In the absence of Rho, what can bring about transcription termination? | GC-rich region near the 3' terminus followed by 4 to 8 uridines |
