human body. They are capable of infecting and hijacking a human body, creating health hazards as minor as the common flu and as disastrous as the AIDS epidemic. Viruses have many types; one is an RNA virus. RNA virus is a virus that has RNA as its genetic material. One of the human diseases that is caused by RNA virus is the Ebola virus. In order for someone to be infected by Ebola, one must come into contact with the virus. It can enter the human body through the nose, mouth or breaks in the…

Cell biology 1. A cell is eukaryotic because  Is generally larger and much more sophisticated than prokaryotic cells due to the presence of a complex series of membranes that divide a typical eukaryotic cell into compartment.  Eukaryotic cell has an organized nucleus with a nuclear envelop.  Has membrane bound organelles  Contain linear DNA molecule that are larger than the (circular) DNA molecules in prokaryotic cells and, in association with proteins, form structures called chromosomes.…

Construction of DNA, RNA, And Protein By Building Models Introduction Nucleic acids are made of nucleotides. When these nucleic acids form sequences they create either DNA or RNA. DNA and RNA are composed of a phosphate, a sugar, and a nitrogen base. The main difference in RNA and DNA is that uracil replaces the base of thymine in RNA. Proteins are essential to maintaining cells by creating hormones and enzymes, and defending the cell. The arrangement of DNA and RNA bases dictates what protein…

smaller. This new friend would be called RNA, and through gene expression, would create a polypeptide. DNA decided, that in order to insure the completion of gene expression, she would create messenger RNA that would be called mRNA for short. The process of created this new mRNA was called transcription and would use the information DNA possessed. First, DNA had to decide which gene to transcribe, and because it was her first time transcribing RNA, she decided to transcribe a short…

The article, “Does the Ribosome Challenge our Understanding of the RNA World?,” by Anthony Poole was published in the Journal of Molecular Evolution. RNA world hypothesis is a model framework explaining the origin of life on earth like genetically translated proteins and deoxynucleic acid from the point of view of ribonucleic acid based hypothetical systems. It suggests that ribonucleic acid existed before the deoxynucleic acid molecule. Chemical and Darwin’s evolutionary theories attempt to…

Similarly, peroxisomes degrades toxic compounds. Another small organelle is Ribosomes. RNA is used to synthesize proteins and can be found in the large number of Ribosomes. Endoplasmic Reticulum is involved in the transport of many materials. ER is made of two different types, smooth and rough. Centrosomes are also present and they contain…

many observable characteristics seen in an organism. Information encoded in the DNA inside of nucleus of living cell must go though many stages: DNA~RNA~Protein with various other steps before the final product. A copy of the DNA facilitates information in genes to become available for protein synthesis. Pre-mRNA is the first sequence and then messenger-RNA is the final step before protein. Different parts of the sequence is removed through a process called splicing. Some parts of the Pre-mRNA…

most visible structure within the nucleus is the nucleolus, which is where rRNA is made and ribosomes are assembled. The nucleus has a double membrane which has large pores, 40-100um in diameter. That makes it easier for larger molecules such as RNA to pass into the nucleus. The most visible structure within the nucleus…

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) make up the nucleic acid in cells and is responsible for the differences in many of our traits. DNA is the substance in which our genetic material is carried on from one generation to the next. Nucleotides join together through phosphodiester linkages between the 5 ' and 3 ' carbon atoms to form nucleic acids. “Nucleotides are composed of a five-membered sugar group with a purine or pyrimidine nitrogen base group attached to its 1 ' carbon…

and RNA these building blocks are nucleotides, which are composed of purines, pyrimidines, sugars, and phosphoric acid. If amino acids are dissolved in water they do not spontaneously join together to make a protein. That would require an input of energy. If proteins are dissolved in water the chemical bonds between the amino acids slowly break apart, hydrolysing the protein and releasing energy. The same is true of DNA and RNA. DNA, as well as messenger-RNA, transfer-RNA, and ribosomal-RNA, is…
