DNA replication

1.2 Cellular DNA Damage responses, genomic instability. DNA is the blue print of life and all the information of life processes such as growth, metabolism, reproduction etc are encoded in the sequence of it. Therefore its very important to maintain the genomic integrity of this genetic material, not only to keep away defects in life processes but to pass a faithful information to the next progeny. Integrity of the DNA is usually challenged by both endogenous and exogenous agents who are capable…

product. This process is how DNA is coded for RNA, which basically is the turn code for the proteins in our body. DNA is in every living thing, which is the molecule that carries genetic material from the parents to their offspring. Basically, it is the most important thing in the human structure of the body. For it carries the necessary information that is needed for the construction of proteins and RNA. There is always decoding going on in the body which is using the DNA information and using…

Replication Inhibitors Replication inhibitors interfere with DNA synthesis. There are many of these inhibitors, but they typically work via two main mechanisms. One of these mechanisms involves either disrupting molecules that are needed for DNA polymerization or those needed in order to initiate replication. The other mechanism is by interfering with replication checkpoints that are involved in regulating the replication process. These checkpoints sometimes do this by triggering certain…

This paper is going to describe the replication of DNA and RNA and the processes of transcription and translation of protein synthesis. What is DNA? DNA is a nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA sequences are replicated by the cell prior to cell division and may include genes,…

Parvovirus is a SS DNA virus, as stated in question it’s genome is either + or – strand. Their genome is linear, non segmented, and single- stranded DNA of about 5 KB. Most of the strand packaged into virions are – strand, but some parvoviruses package equal amounts of (+) and (-) strand. Parvovirus can’t become latent, since they are ssDNA and will be destroyed. All parvoviruses require receptor-mediated endocytosis for cell infection. Their host is Mammals including humans, parvovirus has all…

most part, genes are responsible for pairing DNA bases with the correct base, and directing the production of RNA molecules, which synthesizes proteins and regulates the expression of other genes, but when some genes are altered or manipulated during DNA replication, they can be very dangerous for the body, and can be possibly deadly. Some of the genes in our body that are mutated can play a positive role in the body in ways such as smoother DNA replication and recombination. Other genes that…

chromosomes, each of these chromosomes are a housing unit for DNA. DNA, also known as deoxyribonucleic acid, is a simple molecule found in all living organisms. DNA has a unique structure, made up of a double helix, base pairing, and hydrogen bonding, all working together to make it stable. The double helix is made up of a phosphate backbone. These phosphates create a bond between the sugars and themselves,…

only one way based on Chargaff’s rule. b) Franklin’s x-ray diffraction photographs showed that the wet form of DNA likely had a double helix. Wilkins showed Watson Franklin’s results and at the time Watson and Crick were experimenting with many potential models of having 1,2 or even 2 strands. As soon as Watson saw the double helix, he knew the double strand model was correct. 29. DNA contains phosphorus but very little sulfur and protein contains sulfur but very little phosphorus. Hershey…

The exponential growth of social media has spurred the creation of a unique form of communication in today’s culture. What do I meme? The use of the Internet meme has served as a phenomenon that has changed the way people communicate and have had a notable influence on forms of cultural expression. Memes are defined as, “an idea, behavior, style, or usage that spreads from one person to another in a culture and often altered in a creative or humorous way (i.e. images, phrases, snapshots, gifs,…

information in the form of chromosomal DNA. Chromosomes can be circular in prokaryotic, or simpler single-celled organisms such as bacteria, but tend to be linear in more complex eukaryotic cells. The replicon, or the enzymatic complex that replicates DNA has limitations on its efficiency and capabilities. For example, eukaryotic DNA polymerase requires a short RNA primer to begin replication on the lagging strand, because of this replication cannot continue replication all the way to the end…
