- Hydrogen 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.Heterochromatin and Euchromatin Have Which Different Histone modificationsName: Clas: Date: Transcription 3" ATGACGGATCAGCCGCAAGOCGGAAfTGGCGACATAA UACUGCCUAGUCGGCGUU 3 5' WA WAW TACTGCCTAGTCGGCG TCGCCTTAACCGCTGTATT 3' 6 Label the diagram as you read the following passage. Transcription is the process cells use to copy information from DNA into messenger RNA copies. Part of the chromosome's tightly wound-up long strand of DNA is "loosened" to allow for RNA polymerase room to copy part of the DNA. Think of this as opening a page out of a giant book with thousands of pages to make a copy of just that one page. One side of the DNA strand is the template strand (or anti-sense strand) and is used by an enzyme called RNA Polymerase to create the messenger RNA. RNA Polymerase is directed by a bunch of proteins called transcription factors to the spot it needs to start copying. RNA Polymerase reads the template strand from the 3' end to the 5' end and creates a messenger RNA strand that is complementary to the template strand. In the diagram above, you can see that…

- (b) (c) Point mutations in multiple tumor suppressor proteins have been linked to cancer. For example changes in the gene for adenomatous-polyposis-coli protein (APC gene) may result in colorectal cancer. Consider the following DNA sense strand. 3-TAC CGG TTG TGA AGC TGA ATC-5' Derive the mRNA molecule from the given DNA strand sequence above, paying attention to the polarity of the molecule. (i) (ii) (iii) (iv) Write down the polypeptide chain sequence arising from the mRNA molecule of the question above, using the table of the genetic code (Table Q1 overleaf) and indicate the C- and the N-terminus of the peptide chain. Point mutations of a cytosine (C) often lead to the dysfunction of the APC protein. Write down all possible polypeptide chains that can result from all possible DNA mutations of cytosines, disregarding a mutation in the MET/START and STOP codons.

Chromatin modifications DNA methylation Post-transcriptional processing Post-translational modificationsI. The retinoic acid receptor (RAR) is a transcription factor that is similar to steroid hormone receptors. Thesubstance (ligand) that binds to this receptor is retinoicacid. One of the genes whose transcription is activatedby retinoic acid binding to the receptor is myoD. Thediagram that follows shows a schematic view of theRAR proteins produced by genes into which one oftwo different 12-base double-stranded oligonucleotides had been inserted in the ORF. The insertion site(a–m) associated with each mutant protein is indicatedwith the appropriate letter on the polypeptide map.For constructs encoding proteins a–e, oligonucleotide 1(5′ TTAATTAATTAA 3′ read off either strand) wasinserted into the RAR gene.

What would be the synthesized mRNA strand, and how is it transcribed from the original DNA strand, and then converted from a pre-mRNA strand to a mature mRNA? Where in the cell does this occur? 3. What would be the anti-codons for the tRNA. What are the amino acids generated based on the RNA. How are these amino acids translated into protein and where in the cell does this happen?Complete the protein synthesis for the partial DNA sequence for a normal FGFR3 gene (TOP) and mutated FGFR3 gene (BOTTOM).
