True or false:
For each protein-coding gene, there is one promoter and one enchancer that act as regulatory elements for that gene.
Step by step
Solved in 2 steps with 2 images
- True or False: there are three different start codons in the genetic codeTrue or False? Eukaryotic genomes are organized into operons; each operon consists of a series of genes which code for enzymes involved in a metabolic pathway, under the transcriptional control of a single promoter sequence .TRUE OR FALSE: tRNA-met complexes with mRNA at the aminoacyl-site of the ribosome
- Promoters of the INS gene"After a sudden increase in transcription, a protein with a slow rate of degradation will reach a new steady state level more quickly than a protein with a rapid rate of degradation." is true or false.True or False; explain It is possible that the coding region of a gene is present in a genomic library produced from a particular tissue, but is absent in cDNA library prepared from the same tissue.
- To be considered a transcription factor, a protein must bind the DNA. True or FalseThe possibility of a single locus in a DNA to code for different mRNAs. If this is possible, what would be the implications?True/False: In general, weak promoters that support active transcription have -10 and -35 boxes that are close to the consensus sequences and a spacer between the two boxes that is 17 +/- 1 bp.
- TRUE or FALSE: "The initiation codon for both prokaryotes and eukaryotes is AUG coding for the same amino acid - methionine."Which regulatory proteins binds to specific DNA sequences with high affinity and plays a pre-dominant role in determining whether a genome segment is transcribedThe genetic code is both universal and degenerate. Explain how these aspects are an advantage, but also a potential disadvantage to heterologous protein production.
