Question
Chapter 29, Problem 7P
Interpretation Introduction
Interpretation:
The reason as to why the replication come to a halt in the absence of topoisomerase II is to be stated.
Concept introduction:
DNA stands for deoxyribonucleic acid, is a biological macromolecule. DNA contains double helical strands along with the complementary base pairs. The four complementary bases of DNA are adenine (A), thymine (T), guanine (G) and cytosine (C). In the formation of recombinant DNA, the restriction enzymes are involved to cut the particular region in the DNA molecule.

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.
Please help me solve this problem. I am really having a hard time understanding this lesson. Please help. Kindly provide all the necessary information to this problem. Thank you! Please answer numbers 1-5
determine what amino acid will be formed from the given DNA strand below:
3’ T A C A T G C C G A A T G C C 5’
Note: Prepare the partner strand of this DNA. Discuss how will replication happen by mentioning the enzyme needed then transcribe to form mRNA. Discuss what will happen to mRNA, then translate, mentioning the anticodon to be used. Look at the genetic code to know what amino acid will become part of the polypeptide chain.

- TRUE or FALSE. If false, write the word/s that make(s) the statement incorrect. 1.The 2 subunits of DNA PoI II are called clamp loader and sliding clamps. 2. In eukaryotes, replication and transcription occur in the nucleus, while translation occurs in the cytoplasm.arrow_forwardTrue or False. 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_forwardplease help me with this question. As this is a non-directional cloning, recombinant plasmids can contain an insert ligated into the vector in two different orientations.

In one type of mutation leading to a form of thalassemia, the mutation of a single base (G to A) generates a new 3' 3' splice site (blue in the illustration below) akin to the normal one (yellow) but farther upstream.
