a protein represents: (*) the amino acid sequence. (2) the functional configuration. (3) the subunits of a protein. (4) a pleated sheet. (5) a alpha helix. 2. In prokaryotes‚ most genes are organized into operons. One component of an operon is the structural genes. Which of the following best describes a structural gene? (*) a sequence of DNA that specifies a polypeptide. (2) a sequence of DNA that produces tRNA’s. (3) a sequence of DNA that interacts with the small ribosomal subunit. (4) a sequence

genetically modified organism. The term is generally used for food that has had its genes changed using biotechnology. Using genetic modification‚ scientists are able to produce new varieties of plants with certain qualities‚ such as being more resistant to viruses or pesticides. Are GMOs good or bad for us? I thinks GMOs good us and maybe people thinks GMOs bad because that pointed out that transferring a gene from an allergenic food crop‚ such as peanuts‚ could make the GMO food allergenic as

Shwachman Diamond Syndrome (SDS) is an inherited condition that affects mainly the bone marrow‚ pancreas‚ and skeletal system of the human body. Bone marrow produces new blood cells; however‚ in a patient with SDS‚ the bone marrow does not make all of the types of white blood cells making the body more vulnerable to infection. The pancreas produces enzymes that help break down and use nutrients from food. SDS results in the pancreas not producing enough of these enzymes‚ which makes it hard to digest

Do you know that tall‚ skinny kid that towers over everyone? There might be a genetic disorder to explain why he is like that. Have you ever heard of something called Marfan syndrome or MFS? It is a genetic disorder that about one in every five thousand people have and there is a fifty percent chance that it can be passed on to the next generation ("What Is Marfan Syndrome?"). Marfan syndrome is an abnormal condition characterized by elongation of the bones‚ and abnormalities in the cardiovascular

organisms Genetic code is redundant – More than one codon specifies a specific amino acid. For example‚ six different codons specify leucine. 6. What is the difference between an anticodon and a codon? A codon is found in DNA and describes different genes. An anticodon is a stop sequence found in RNA only. 7. Describe

epigenetics is “the study of heritable changes in gene activity which are not caused by changes in the DNA sequence” (“Wikipedia”; n.d.). One can adopt a healthy lifestyle to change the impact of the genes inherited by an offspring. Ornish states that changing eating habits‚ loving more‚ and getting more exercise can cause a large increase in brain cells. (“ted.com/speakers”; n.d.) These changes could also impact the number of disease provoking genes that one will pass on to an offspring. It is

and even repeats‚ which ultimately can result in a nonfunctional protein. The APC gene produces a protein known as the APC protein that is involved in regulating cell adhesion‚ signal transductions‚ and transcription activation. Park and Vogelstein (2003) stated that‚ “the localization of the APC protein is in the basolateral membrane of the colonic epithelial cells…” When mutations occur within this specific gene‚ it causes excessive proliferation of the colonic epithelial cells‚ which result in

The Monstrosity in Victor and The Creature Throughout the novel‚ the idea of monstrosity is expressed straightforwardly. Between the Creature’s hideous image and Victor’s abuse of knowledge‚ it’s hard to tell who the real monster is in the story. Standing at eight feet tall and with grotesque bodily features‚ the Monster is shunned by the world. He was created out of many stolen body parts and brought to life in the most unusual way. He is not only brought to life by Victor’s workings with

1.8.1 Pre-S/S Open Reading Frame (Pre-S/S ORF) The pre-S/S ORF has three in-frame translation initiation codons that divide the gene into the pre-S1‚ pre-S2 and S regions which encodes the large (L)‚ middle (M) and small (S) envelope proteins‚ respectively (Tiollais et al.‚ 1985) . The S protein is 226 amino acids long‚ has a molecular mass of 25 kDa and shares DNA and amino acid sequence as the C-terminus of the M and L protein. The M protein has a 55-amino acid extension to the S protein
