The eukaryotic chromosomes are linear DNA molecules with free 3'-OH and 5'-PO3- ends. DNA free ends are signals of double strand breaks, which are highly detrimental for the cell. Using the diagram below as a reference, describe structurally how telomeres resolve this problem. Make sure to highlight the interactions involved, the nature of the telomeric sequences and the correct nomenclature for the structure formed. 5' Telomeric DNA TTGGGGTTGGGGTTGGGG 3' TGGGGז AACCCC AACCCCAACCCC AACCCCAACCCC Non-telomeric DNA TTGGGG 3' TGGזGG AACCCC. 5' AACCCC AACCCC TTGGGG TTGGGG TTGGGGTTGGGGTTGGGG AACCCCAACCCCAAC C AACCCC TGGGGז

Given the coding strand DNA sequence below, what change would occur in the expressed protein sequence if a mutation resulted in insertion of C between the final two nucleotides? 5'-AATGCCGTAA-3' Expressed protein would be extended (lengthened) O Correct answer not given No change would occur in the expressed pratein OExpressed protein would be truncated (shortened) OA single amino acid in the expressed protein would be substituted

Within living cells, many different proteins play importantfunctional roles by binding to DNA. Some proteins bind to DNA butnot in a sequence-specific manner. For example, histones are proteinsimportant in the formation of chromosome structure. The positivelycharged histone proteins bind to the negatively charged phosphategroups in DNA. In addition, several other proteins interact with DNAbut do not require a specific nucleotide sequence to carry out theirfunction. For example, DNA polymerase, which catalyzes thesynthesis of new DNA strands, does not bind to DNA in a sequencedependentmanner. By comparison, many other proteins do interactwith nucleic acids in a sequence-dependent fashion. This means that a specific sequence of bases can provide a structure that isrecognized by a particular protein.Someexamples include transcription factors that affect the rate oftranscription and proteins that bind to origins of replication inbacteria.What topic in genetics does this question address?

How are deoxyribonucleoside triphosphates (precursors of daughter DNA strands) and ribonucleoside triphosphates (precursors of RNA strand) differ from each other?
