After sequencing a new genome for the first time, functional protein-coding genes are initially identified by: BLAST searches that look for viral integration in the host genome Bioinformatic searches that reveal consensus sequences in expressed genes Aligning expressed exons sequenced from cDNA using transcriptomics B and C A and B
Beadle and Tatum's experiments led to the "one gene - one enzyme (protein)" hypothesis. In subsequent years, many exceptions to this hypothesis were noted. A molecule of hemoglobin fails to support this hypothesis for which of the following reasons? n eukaryotes, one gene can code form multiple isoforms of a polypeptide. The functional hemoglobin protein is made from multiple polypeptides. Not all enzymes are proteins. Not all genes encode proteins.

The diagram below shows a hybridization experiment between a eukaryotic MRNA and the template strand of its gene. Which of the following statements is FALSE? This gene contains four exons. The 5' end of the MRNA is on the left side. Hybridization of a prokaryotic MRNA and its DNA template strand will not show loops of unpaired DNA. The gene's introns are visible as unpaired DNA loops.

Mutations in DNA may or may not result in a change in the phenotype of an organism. In which of the following situations will a mutation appear in the phenotype of an individual? The mutation occurs in an organism which is past reproductive age The genetic code for protein synthesis has not been altered in a gamete producing cell The mutation occurs in a body cell of the organism, resulting in cancer O The mutation results in a change in the amino acid sequence of the protein in a gamete producing cell
Consider gene expression in a eukaryotic cell. Which of the following is true for transcription in this cell? Select all that apply. MRNA has to be processed before leaving the nucleus MRNA can be synthesized by Transcription and at the same time this mRNA can be used for protein synthesis or Translation RNA polymerase requires several transcription factors for efficient transcription initiation During Transcription, the enzyme topoisomerase relaxes negative supercoiling in the DNA strands
Which of the following statements about mutations are true? * Mutations are always passed down to future generations. Mutations decrease the genetic diversity of organisms. Mutations occur only in somatic cells since they are diploid. Mutations are changes in the phosphate backbone of DNA which always have harmful effects. Mutations always cause a frameshift. Mutations can be harmful, neutral, or beneficial to the organism. Mutations are changes in the nucleotide sequence of a DNA molecule. Mutations may cause a change in the protein sequence resulting from the genetic code for that gene.
