Nitrogenous Bases Amino Acids
999 wordsDeoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20 th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. DNA is the genetic material found in most viruses and in all cel...

Amino Acids Dna Molecule
1,152 wordsIntroduction Deoxyribonucleic acid is contained in all cells. The structure of DNA makes gene transmission possible. Since genes are segments of DNA, DNA must be able to make exact copies of itself to enable the next generation of cells to receive the same genes. The DNA molecule looks like a twisted ladder. Each "side" is a chain of alternating phosphate and deoxyribose sugar molecules. The "steps" are formed by bonded pairs of purine-pyrimidine bases. DNA contains four such bases the purines a...

History Of The Human Genome Project
1,354 wordsThe Human Genome Project (HGP) is an international research effort to decipher the entire human genome and understand the unique hereditary instructions that each person possesses. The HGP is a jointly funded project by the U. S. Department of Energy (DOE) and the National Institutes of Health (NIH) with additional research done by the National (NHGRI). The project, launched in 1990, was originally planned to last 15 years, but rapid advances in technology have accelerated the expected completio...

Small Amount 30 Seconds
717 wordsPCR And Its Use Often times, scientists only have a small amount of DNA to deal with when doing genetic research or studies. In these situations, scientists can do one of several things. One is to just try to work with it anyway, but this is nearly impossible (depending on how much there is). Ther are a couple other processes they can use, or they can use PCR. PCR is one of the more complicated, but reliable ways to do tests on DNA when they only have a small amount to begin with. PCR, or Polyme...

Cystic Fibrosis Endoplasmic Reticulum
717 wordsCystic Fibrosis Commonly found in young children, Cystic Fibrosis is an inherited disease that is caused by a genetic disorder. The disease originates in the production of a critical protein that transports chloride ions from one place to another called a cystic fibrosis transmembrane conductance regulator (CFTR). The DNA of an infected person is missing three building blocks called nucleotides causing the CFTR protein to be missing one amino acid called phenylalanine. Normally, a healthy CFTR p...

Base Pairs Double Helix
610 wordsThe molecule responsible for the transformation of characteristics form one generation to the next is called DNA. The genetic material, located in the chromosomes is a combination of acid and histones. DNA is made up of units called nucleotides. Nucleotides are made up of 3 components, a five carbon sugar (deoxyribose), a phosphate group, and a nitrogenous base. This base can be either adenine, guanine, thymine or cytosine. There are 2 strands of nucleotides in a double-helix they are anti-paral...

Nucleic Acids Genetic Material
948 wordsNucleotides are important to the structure of DNA. In this essay, I defined the term and explained what the function of a nucleotide is through explanation and illustration. A nucleotide, as defined in my computer? s Microsoft Bookshelf, is a subset of the DNA ladder shown in question number one. They are the building blocks of nucleic acids, and are half of one of the ladder? s? rungs? and its support beams. Nucleotides make up the double helix, and the sequence of them determines the cell? s g...

Amino Acids Alzheimer
1,948 wordsDNA: The Making Lyle Sykes For more than 50 years after the science of genetics was established and the patterns of inheritance through genes were clarified, the largest questions remained unanswered: How are the chromosomes and their genes copied so exactly from cell to cell, and how do they direct the structure and behavior of living things? This paper will discuss those questions and the people that answered them. Two American geneticists, George Wells Beadle and Edward Lawrie Tatum, provided...

Amino Acids Dna Strand
892 wordsA mutation is a change in the genetic material that controls heredity. The genetic material is contained in chromosomes, which are divided into genes. Point mutations involve single genes and occur by substitution and insertion or deletion of a single base in DNA. Insertions or deletions, referred to as frameshift mutations, shift the reading of the code by one or more bases so that all amino acids produced after the addition or deletion are affected. Translation is a series of complex biochemic...

Sickle Cell Anemia Red Blood Cells
1,326 wordsThe Protein Site Protein Synthesis The process of Protein Synthesis involves many parts of the cell. Unlike other similar productions, this process is very complex and precise and therefore must be done in proper sequence to work effectively. The slightest error during this process could cause the action to experience difficulty or even fail. For example, in the production of starch, glucose molecules are combined to be stored and eventually utilized as usable chemical energy. The cell can break...

Protein Synthesis Amino Acids
788 wordsProtein synthesis is one of the most fundamental biological processes. To start off, a protein is made in a ribosome. There are many cellular mechanisms involved with protein synthesis. Before the process of protein synthesis can be described, a person must know what proteins are made out of. There are four basic levels of protein organization. The first is primary structure, followed by secondary structure, then tertiary structure, and the last level is quaternary structure. Once someone unders...
