Attack on data always happens without the person involve realize about it. This is why data encryption is important. Data encryption using asymmetric key is one of the most trustable data security algorithm. When the sender wants to send data or message, data encryption will change the data to an indecipherable state by using algorithms or theorems. Data encryptions are initially used by the authority military to communicate with each other during the old days.
DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual, as shown in the image below. DNA fingerprinting is also used to establish paternity, which can be important in finding the origin of the individuals through DNA and identifying the bloodlines of the DNA profile, which has occurred through evolution. Cited from GeneEd, (U.S. National Library of Medicine. Genetics, Education, Discovery). DNA profiles is very important in cloning as it will be used to identify or study an individuals private DNA sample, which can be positive in the study but negative in their privacy.
Abstract : Steganography is the methodology in science that involves communicating secret data in an appropriate multimedia carrier for e.g. video, audio and image files. Audio steganography hides data in a audio signal which is a cover signal without any modification in that cover signal. Generally, Steganography concept is confused with other technique such as cryptography and watermarking, but objectives such as imperceptibility, capacity of hidden data and robustness draws thin line between them. The prime goal of steganography is to reliably send hidden information secretly, and not to reveal its presence.
What is cryptography? Cryptography is the study of utilizing science to encode and unscramble information. Cryptography empowers you to store delicate data or transmit it crosswise over frail systems (like the Web) so it can't be perused by anybody aside from the expected beneficiary. While cryptography is the study of securing information, cryptanalysis is the study of examining and breaking secure correspondence. Established cryptanalysis includes a fascinating mix of systematic thinking, use of numerical instruments, example discovering, tolerance, determination, and good fortune.
If any kinds of incident happen then it will be the evolution to identify the criminal. Not only that, it will provide the criminal exact address. But, before implementation this technology it is very much important to merge the national identity database and the surveillance system server. On the other hand, every security surveillance system has to link with a single secure server.  In a free country safety and security is in high priority.
SOPHIA COLLEGE Protein-DNA Interaction MAYUR GAIKWAD 05/05/2015 INTRODUCTION Protein–DNA interactions play a major role in all fields of genetics from regulation and transcription of individual genes to repair of damaged sequences, even to the stabilization of DNA in chromatin and the replication of entire genomes. It is estimated that 2–3% of prokaryotic and 6–7% of eukaryotic genes code for DNA-binding proteins. Additionally, many of these proteins do not merely bind DNA, but also interact with other proteins and sometimes, as is shown in the example of RNA polymerase, only display theirfull activity when organized in multimeric complexes. SEQUENCE-SPECIFIC DNA BINDING Protein recognition of specific sequences on the DNA double
Homologous recombination (HR) can be explained as a process where DNA is exchanged or copied between two chromosomes or different regions of the same chromosome. The process requires homology between the exchanging DNA regions. Homologous recombination repairs DNA breaks, especially double stranded breaks (DSBs), stabilizes and repairs stalled forks. HR consists of a series of inter related pathways that function in repair of DNA breaks (Figure 4). Initially, stretches of single stranded DNA (ssDNA) are resected at the stalled forks or DSB ends which are quickly bound by replication protein A (RPA).
3. Explain how genes, chromosomes, DNA, and genomes all relate to one another and their importance to psychology. Genes are the biochemical units of heredity that makes up the chromosomes; a segment of DNA capable of synthesizing a protein. Chromosomes are threadlike structures made of DNA molecules that contain the genes. DNA is a complex molecule containing the genetic information that makes up the chromosome.
INTRODUCTION Steganography is the art or practice of concealing a message, image, or file within another message, image, or file. The word steganography is of Greek origin and means "covered writing" or "concealed writing”, Cryptography and Steganography are ways of secure data transfer over the Internet. Cryptography scrambles a message to conceal its contents; steganography conceals the existence of a message. It is not enough to simply encipher the traffic, as criminals detect, and react to, the presence of encrypted communications. But when information hiding is used, even if an eavesdropper snoops the transmitted object, he cannot
