in RNA extraction we don't need to use a strong lysis solution to the cells like in DNA extraction
since we don't need to break the nuclear envelope in case of RNA*.
*Be cautious, in some case (ex. hnRNA) the RNA is in the nucleus so you have to break it. Really depend on what you are looking for.
To study genomic makeup, variations or gene expression, DNA and RNA from cells have to be isolated before any more tests can be conducted. Reasons for isolating genomic DNA include genome sequencing and comparative genomic hybridization (a method for determining gene copy number changes in abnormal cells). Isolating plasmid DNA from bacteria is essential to the processes of bacterial transformation and molecular cloning. Isolating total RNA from a cell is usually used to make cDNA for other uses (such as insertion into an expression vector or microarray analysis) or used for gene-expression studies such as real-time PCR.

DNA isolation is a based on the principle of purification. DNA samples are isolated through the use of physical and chemical methods. Friedrich Miescher conducted the first isolation of DNA in 1869.
No difference
Another answer could be that Transcription uses Uracil. This is the answer I got from Apex btw.
Extraction Buffer is used to maintain pH of the solution.which prevents denaturation of DNA.

Boric Acid is an extraction buffer used in the isolation of DNA and when it is employed with a correct pH then it can help in getting rid of the cell components without disturbing the cell organelles i.e it retains the organelles.
They are the same (if you are talking about genomic DNA)
There are several differences. First, you use different materials to conduct each proceedure. With plants, you need baking soda, with human DNA you do not. Also, with human DNA you do not want to mix your mixtures. You want to keep your tube still. With plant DNA, you have to flick your test tube to make the DNA appear. These are just a few of the differences in the proceedures.
The word detergent is used instead of soap in a DNA extraction buffer. Detergent is used to create a hydrophobic environment that favors the precipitation of proteins. Proteins are one of two major contaminants in DNA extraction (the other major contaminant being RNA). When protein precipitate, they can be separated by centrifugation and the DNA isolation procedure can continue.
2-Mercaptoethanol is often included in extraction buffers designed for plant DNA extraction, because it is a strong reducing agent which can remove tannins and other polyphenols often present in the crude plant extract. It may also help to denature proteins by breaking disulphide bonds between cysteine residues.
kit that is used for dna extraction is called as dna extraction kit here the chemicals that are used for the extaraction are provided in the kit itself many biotech companies are selling those kits

DNA extraction from bacteria can be achieved in various ways. Yeast is the best resource to extract the DNA bacteria from using extreme rapid extraction method.
In a DNA extraction, the purpose of a buffer is to solubilize DNA as well as RNA. Because of this, it prevents the DNA for degrading.
