A. Eighty codons are possible. B. Three codons signal the end of a gene. Answer C. Seventy codons specify amino acids. D. Each amino acid has one codon. Rationale: Three codons signal the end of a gene, and they are called stop or nonsense codons. QUESTI...

How does translation terminate? - ️️-stop codon (UAA, UAG,UGA) -instead of tRNA, release factor binds to ribosome, causing hydrolysis of the peptidyl tRNA, releasing the completed protein -ribosome dissociates into its subunits, releasing mRNA, release factor, and tRNA mRNA and protein synthesis are very energetically - ️️adding each subunit requires the conversion of an NTP to an NMP, equivalent to hydrolyzing 2 ATPS to ADP -elongation step consume multiple ATP/GTP -splicing and ...

Transcription synthesis of RNA from DNA Transcription results in mRNA RNA polymerase makes mRNA mRNA makes proteins RNA polymerase binds to DNA Transcription factors (TFs) A regulatory protein that binds to DNA and affects transcription of specific genes. Can wither activate or repress expression of genes Termination of transcription RNA polymerase reaches a terminator sequence (Stop codon) and detaches from the templateTranslation Process by which mRNA is decoded and a protein is produc...

Briefly explain how the base pairs A-T and C-G bond to each other and why the interactions they form are important to DNA unwinding. Base pairs form hydrogen bonds to each other. G and C form 3 hydrogen bonds, while A and T form 2 hydrogen bonds. These hydrogen bonds are weak electrostatic interactions that are able to hold the DNA together but are easily broken for the DNA to unwind. Why are telomerase inhibitors an attractive prospect for cancer therapies? >90% of cancer cells expres...

What is the minimum number of nucleotides per amino acid required to specify all 20 amino acids? Correct Answer-3 nucleotide bases per amino acid Codon Correct Answer-a triplet of nucleotides that codes for a specific amino acid Translation occurs in such a way that these nucleotide triplets are read in a successive, nonoverlapping the key to the translation of genetic information, directing the synthesis of specific proteins Overlapping Correct Answer-AUACGAGUC -> is read like AU...
