Question
Chapter 4, Problem 10P
Interpretation Introduction
Interpretation:
Why do DNA strands have opposite polarity in double-helix structure?
Concept introduction:
Sugar-phosphate backbones in DNA run in opposite directions. The strands of DNA will form a double helix only when they are opposite in direction.

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?
Please help me with the orange question.
My answer is leading strand will encounter lagging strand.
I dont know if it’s correct.
Thank you

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.
