Question
Chapter 29, Problem 16P
Interpretation Introduction
Interpretation:
The maximum number of base pairs that could be broken per ATP hydrolyzed by a helicase operating under standard conditions needs to be estimated.
Concept introduction:
In replication, the two strands of double-stranded DNA molecule needs to be separated from each other for a sort local stretch. This needs helicases with association with ATP hydrolysis.

True or False. Topoisomerase I does not require ATP to break and rejoin DNA strands because the energy of the phospho-diester bond is stored transiently in a phospho-tyrosine linkage in the enzyme’s active site. Explain your answer in 2-3 sentences.
True of False. Explain.

Just write T if it is true and F if it is false. In E. coli both RNA and protein synthesis take place in the cytoplasm. Okazaki fragments are ssDNA CHAINS OF 100-200 nucleotides long, primed by very short RNA primers in bacteria. In eukaryotic gene, the coding sequences are known as introns while the intervening sequences are the exons. The central dogma refers to the fact that proteins are products of information encoded in RNA using a DNA intermediate. The ends of the linear chromosomes are maintained by telomerase to prevent it from shortening during mitosis. The Shine Delgarno sequence is where the RNA pol binds during transcription in prokaryotes The sigma subunit of the E. coli RNA polymerase confers specificity to transcription. Both DNA replication and transcription follow a 5’ to 3’ direction of polarity. Nucleosomes are the structural unit of chromatin. In the lagging strand, the enzyme X removes RNA primers attached by PRIMASE and this gap is then filled…arrow_forward

- This is DNA. Locate the nitrogen bases (nitrogens are blue). Where are they located in the molecule?Locate the sugars and phosphates, and describe their location. Adjacent nucleotides are linked by covalent phosphodiester bonds (-O-P-O-) produced by a condensation reaction. What parts of the adjacent nucleotides are linked by phosphodiester bonds?Two nitrogenous bases extending towards the middle of the double helix. Are there any covalent bonds between these bases?If there are no covalent bonds between these bases, what other kinds of bonds might hold the two strands of the double helix together?arrow_forwardTrue or False. In a comparison between the DNAs of related organisms such as humans and mice, conserved sequences represent functionally important exons and regulatory regions, and non-conserved sequences generally represent noncoding DNA.
