Exam 14: Translation and Proteins

If humans had 25 amino acids instead of 20 amino acids then how many aminoacyl tRNA synthetases would humans have?

Provide five reasons why translation is more complex in eukaryotes compared to bacteria.

Three major types of RNAs are mRNA,rRNA,and tRNA.For each of the conditions below,predict the conseque terms of the population of proteins being synthesized in a particular cell and the effects on individual proteins. a)An acridine dye-induced mutation adds or deletes single bases in DNA)leads to an mRNA for one protein- producing gene.The condition is heterozygous in the involved cell. b)A deletion homozygous)that removes approximately half of the rRNA genes.

A protein is 300 amino acids long.Which of the following could be the number of total nucleotides in the section of DNA that codes for this protein? Remember: DNA is double- stranded.
