Describe The Relationship Between Genes Dna And Rna Essay
Describe the functions and relationship between genes, DNA, Chromosomes, and RNA DNA also known as deoxyribonucleic acid is made up of nucleotide. These nucleotides are arranged along the backbone. It is generally used to make protein. DNA are often called the blueprint of life since it contains all components of a cell. Genes are known as the basic unit of inheritance. Human traits are passed on one generation to another in the form of genes. Chromosome are long strands of DNA. Chromosomes contain many genes with stretches of DNA. Chromosomes are wrapped around proteins called histones. To make a protein, DNA mush be unwound from its histones. This is a control the body has over the production of proteins. RNA also known as the ribonucleic acid, it is a single strand of nucleotide unit. Sugar is DNA is deoxyribose while in RNA it is ribose.

This is an inherited disease that causes a progressive breakdown of nerve cells in the brain. It is associated with memory loss, depression, and hallucinations. Symptoms may include arm jerks, involuntary writing movements, abnormal eye movements, and facial twitches. This disease is progressive and incurable.
What is polysomnography? Describe the three techniques used to produce a polysomnography This is a test used to study and records the brain waves, oxygen level in the blood, heart rate and breathing also the eye and leg movement during sleep. Electroencephalogram: used to measured and record brain wave activity. Electromyogram: used to record muscle activity such as face twitches, teeth grinding, and leg movement. Electro-oculogram: used to record the eye movements. Electrocardiogram: used to record heart rate and rhythm.

1168 Words | 5 PagesDeoxyribonucleic acid (DNA) is a molecule found in all forms of life that is passed down from parents to offspring. What makes each DNA unique is the chemical makeup of the molecule sometimes referred to as the “blueprint of life.” (BIO). DNA is made up of nucleotides consisting of a sugar, a phosphate and a base pair. About six million nucleotide base pairs make up DNA in each cell.

Differences Between RNA And DNA
811 Words | 4 Pages1a. Review: Describe three main differences between RNA and DNA. The three main differences between RNA and DNA are as follows: RNA has the sugar ribose instead of deoxyribose, which DNA has, RNA is single-stranded while DNA is double-stranded, and RNA uses uracil instead of thymine. 1b.
How Pku Affects Child Development
962 Words | 4 PagesEach living cell in the human body has a nucleus with 23 pairs of chromosomes inside it. In each pair of chromosomes, one chromosome comes from the father and one from the mother. Each chromosome carries units of inheritance known as genes and these genes interact to create a new set of instructions for making a new person. Genes are made of a substance called deoxyribonucleic acid (DNA). The DNA contains the instructions for producing proteins; it is these proteins that regulate the development of a human being.
Analysis Of When Dna Is Not Destiny By Sharon Begley
402 Words | 2 PagesThe article is “When DNA Is Not Destiny” by Sharon Begley appeared in the Newsweek on December 1, 2008. Begley is a professional science writer who was born in the United States and graduated from Yale University, where she received her Bachelor of Arts degree in 1977. The article discussed whether people should consist the belief of personality is immutable and decided by the genes that we born with. In the article, Begley begins by refuting Wilde’s argument that personality traits are decided at birth and plays a main role throughout one’s life that is constant and unchangeable.
Nt1310 Lab 1
401 Words | 2 Pages1. How does DNA encode information? DNA is a double-stranded helix composed of a phosphate backbone and deoxyribose, and encodes information by the sequence of its nucleotide bases, which are composed of adenine, thiamine, guanine and cytosine. DNA undergoes transcription, which produces single-stranded mRNA, which uses uracil in place of thiamine. Next step is translation, in which the RNA becomes a protein, which then can act as structural units or enzymes.

Concept 3.1 Nucleic Acids Are Informational Macromolecules
1785 Words | 8 PagesConcept 3.1: Nucleic Acids are Informational Macromolecules Nucleic acids are polymers and there are two types, Dna and Rna. Dna is where the information is stored and determines how functions in the body is carried out and Rna how mediates the information. The monomers of nucleic acids(polymers) are made up of nucleotides. Nucleotides are made up of three parts:nitrogen containing base, a pentose sugar and anywhere from 1 to 3 phosphate groups.

456 Words | 2 PagesLiving things are based on a universal genetic code The nucleus (chromatin) contains DNA. Living things grow and develop The nucleus (chromosomes), cytoplasm and cytoskeleton (microtubules and centrioles) allow cell division. Living things respond to their environment The nucleus (DNA & RNA) as well as ribosomes make production of proteins possible.

860 Words | 4 PagesDNA has a massive job of keeping you alive. In essence, a microscopic strand of genes support your entire body and life. There are many smaller jobs protein has to accomplish that combine to accomplish the main job of supporting life. To start, DNA codes for proteins and every protein provide an essential biological function. Also, cells make up tissues, organs, and body systems.
Macromolecules
399 Words | 2 PagesProteins and Nucleic acids are two different macromolecules that are not similar in structure and function. Proteins are a polymer of amino acids. Nucleic acids,on the other hand is a polymer of nucleotides composed of a pentose sugar , a nitrogenous base and a phosphate group.proteins play many important roles in human body including maintenance of structure of cells,regulating mitosis and meiosis,and also controlling body’s metabolism. Main role of nuclec acids(DNA & RNA) is to store the genetic information and pass on to the next generation of each organisms. Even though they are different in structure and function they are closely related to each other.
Four Perspectives In Psychology
814 Words | 4 PagesExplain 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.
Genetic Research Informative Essay
1624 Words | 7 PagesFirst off I want to talk about what is genetics. Genetic research is the differences of DNA between people, the DNA is not the same for every person. Genetics is used to see the DNA differences given from generation to generation. Also genetic research describes differences between the environmental origins of people in an area and time. Many of the DNA strands may not be inherited for example, some mutations in DNA in cells other than the gender cells can sometimes cause cancer but are not transferred and that means it isn’t considered genetic.
