2. At the end of DNA replication, (four/two) new strands of DNA have been produced, giving a total of (four/six) strands of DNA. 3. New DNA is replicated in strands complementary to old DNA because production of new DNA follows the rules of (base pairing/the double helix). Identifying Structures On the lines corresponding to the numbers on the .

The Insider’s Guide to DNA 1 Family history is in our DNA We all have DNA. It’s the genetic code that tells your body how to build you. You inherit half of your DNA from each parent: 50% from Mom and 50% from Dad, though exactly which DNA gets passed down is random. Because they inherited their DNA in the same way from their parents, your .

DNA cytosine methylation is a major epigenetic mark in eukaryotes. In plants, the DNA methyla-tion level in the genome is controlled by de novo DNA methylation, maintenance DNA methylation and DNA demethylation. De novo methylation is mediated by RNA-directed DNA methylation (RdDM), which can occur at all cytosine contexts,

3 DNA is a template in RNA synthesis In DNA replication, both DNA strands of ds DNA act as templates to specify the complementary base sequence on the new chains, by base-pairing. In transcription of DNA into RNA, only one DNA strand (the negative strand) acts as template. The sequence of the transcribed RNA corresponds to that of the coding

DNA Replication 1. Explain semi-conservative replication. Prior to cell division, a cell must make a copy of its DNA to pass along to the next generation. Copying DNA is called “replication”. Rather than build a DNA molecule from scratch, the new DNA is composed of one old DNA strand (used as the template) and one brand new strand.

Discovering basic DNA-binding units A basic DNA-binding unit (DBU) is defined as a com-pact cluster of residues that is supposed to protrude into DNA grooves when a protein binds to DNA. The proposed method discovers DBUs by combining infor-mation of conservation, solvent accessibility, and DNA-binding propensity. Conserved residues are discovered

One of the basic tools of modern biotechnology is DNA splicing, cutting DNA and linking it to other DNA molecules. The basic concept behind DNA splicing is to remove a func-tional DNA fragment—let's say a gene—from one organism and combine it with the DNA of another organism in order to make the protein that gene codes for.

phosphate groups of the DNA are surrounded by a coating of water molecules. Ethanol, added to an aqueous DNA solution, disrupts the electrostatic interactions between the water and the DNA molecules, causing the DNA to precipitate out of solution. Sodium ions (from the salt used in the extraction solution) also disrupt the DNA-water
