Question
The uRIVersal" genetic code is following is true? now known to have exceptions. Evidence for this can be found if which of the A) If UGA, usually a stop codon, is found to code for an amino acid such as tryptophan (usually coded for by UCC onlh B) If a single mRNA found to C) If one stop codon, such as UGA, is found to have a different effect on translation than another stop codon, such as UAA D) If prokaryotic organisms are able to translate a eukaryotic mRNA and produce the same polypeptide. E) If several codons are found to translate to the same amino acid, such as serine molecule is found to translate to more than one polypeptide when there are two or more AUG sites 38) A particular triplet of bases in the coding sequence of DNA is AAA. The anticodon on codon is the tRNA that binds the mRNA B) AAA C) UUA. E) either UAA or TAA, depending on first base wobble. 39) In comparing DNA replication with RNA transcription in the same cell, which of the following is true only of replication? A) The process occurs in the nucleus of a eukaryotic cell. B) It makes a new molecule from its 5' end to its 3 end. C) It uses RNA polymerase. D) The entire template molecule is represented in the product E) The process is extremely fast once it is initiated cell would result in 40) A mutation that inactivates the regulatory gene of a repressible operon in an E. coli A) complete inhibition of transcription of the structural gene controlled by that regulator. B) inactivation of RNA polymerase by alteration of its active site. C) irreversible binding of the repressor to the operator. D) continuous transcription of the structural gene controlled by that regulator E) continuous translation of the mRNA because of alteration of its structure. tails of histones of gametes. A mutation in flies that interferes with this process results in sterility. Which of the following s the most likely hypothesis? 11) In prophase I of meiosis in female Drosophila, studies have shown that there is phosphorylation of an amino acid in the All proteins in the cell must be phosphorylated. ) Histone tail phosphorylation prohibits chromosome condensation Any mutation during oogenesis results in sterility. ) Histone tails must be removed from the rest of the histones. ) These oocytes have no histones. ) Forms of the Ras protein found in tumors usually cause which of the following? ) cell division to cease DNA replication to stop cell-to-cell adhesion to be nonfunctional growth factor signaling to be hyperactive DNA replication to be hyperactiveExplanation / Answer
