You now know genes are transcribed from DNA into RNA in the nucleus and translated from RNA into proteins by ribosomes. Explain the steps of its creation from DNA to protein. Aside for having a nasty inhibitor around like the one from that insecticide, how else might an enzyme end up being non-functioning? During transcription, a base substitution occurred. Explain two reasons why this change in nucleotide sequence could result in no change to the protein.arrow_forwardA template strand of a gene contains the sequence 3’ – TTCAGTCGT – 5’. Suppose that the nontemplate sequence could be transcribed instead of the template sequence. Draw the nontemplate sequence in 3’-5’ order (because remember you have to flip it for your brain to read it like RNA Polymerase would J). Then draw the mRNA sequence and translate it using Figure 14.6 (or any codon chart). Predict how well the protein synthesized from the nontemplate strand would function if at all.arrow_forward

- The diagram below shows a section of double-stranded DNA undergoing both transcription and replication. RNA polymerase (gray oval) is bound to the transcriptional template strand and moving from left to right (arrow). The resulting RNA transcript is also shown (dotted line) with limited base pairing to the template strand. The DNA sequence is specified for a portion of the double-stranded DNA. IMAGE a. Indicate whether point C is a 5' end or a 3' end of a nucleic acid. b. Indicate which strand (upper or lower) is the template for lagging strand synthesis c. Indicate the nucleotide sequence of the RNA that was transcribed from the DNA region specified by the sequence. Label the 5' and 3' ends of this sequence.arrow_forwardConsider how histone proteins bind to DNA and then explain why a salt solution with a high concentration can remove them from DNA (as shown in Figure 12.21b).arrow_forwardHydrogen bonds are important in DNA replication and transcription. They are relatively weak chemical bonds. Why is this a desirable feature for DNA? Describe the effect (s) of changing (mutating) the promoter on the transcription of the DNA strand/gene the promoter controls. What happens to protein synthesis if a nonsense codon is inserted into the gene? Explain why a point mutation does not necessarily change the original amino acid sequence. (Explain silent mutations) Choose any pentapeptide composed of five different amino acids. List the amino acids. Present one messenger RNA codon for each amino acids and the sequence of nucleotides on the DNA that originally coded for your pentapeptide.arrow_forward
