The Importance of DNA in cells
When you look at a baby and recognize how different is your hair or skin color from her, do you know the reason? Cells make up all livings things and they are the most basic unit of life. Humans have eukaryotic cells which make their organisation more complex than prokaryotes. An Eukaryotic cell is divided into organelles: cell membrane, cytoplasm, rough and smooth endoplasmic reticulum, golgi apparatus, mitochondria, lysosomes, cytoskeleton, centrosomes, cilia, flagella (Sperm cell), vacuoles and Nucleus. Every part acts according to its purpose. The nucleus carries the DNA (Deoxyribonucleic acid) and this contains the genetic instruction that an organism needs to develop,

It is made up of nucleotides ( Adenine,Thymine, Guanine, Cytosine) that are connected together to form the double helix molecule. Transcription and translation happen, respectively, in the nucleus and in the ribosome to produce the protein. Similarly, these two activities make different products however, they all develop from the DNA located in the nucleus. According to the textbook, after the DNA strand breaks apart in our spot, the RNA (Ribonucleic Acid) copies all the genetic information to be delivered outside the nucleus for the rest of the formation of protein. With no doubt, this reports that DNA is at the head of the operation concerning proteins. It is the only macromolecule that is going to dictate the nature of the protein to be …show more content…
DNA coordinates all the transmission of the different genes through proteins. In the article Genetic: the study of heredity, the author states that An individual inherits one such unit for a trait from each parent ( Livescience, February 2013). This suggest that parents shares the same DNA with their children. Genes, passed down by parents, can affect the eye color or the behavior of their offsprings. During the pregnancy, the DNA of the foetus give information to his cells to produce a determine color of skin or eye similar to his father or mother depending on the dominant

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.

513 Words | 3 Pages1. Nucleus- present only in eukaryotic cells, this structure stores most of the genetic information of the cell. The nucleus directs the production of proteins through the synthesis of mRNA. 2.
Differences Between RNA And DNA
811 Words | 4 PagesrRNA forms a part of both subunits on a ribosome, in which proteins are assembled. tRNA take amino acids to the ribosome and matches them to the coded mRNA message. 1c. Infer: Why is it important for a single gene to be able to produce hundreds or thousands of
How Did Rosalind Franklin Contribute To Science
581 Words | 3 PagesIn this course, we have studied the many characteristics of DNA which include that it is double helix that contains genetic material and it is kept stable by hydrogen bonds. DNA is made up of smaller units called nucleotides. In turn, each nucleotide consists of a phosphate group, a sugar and a nitrogenous base. DNA also include base pairing which is the 'copying' mechanism for DNA. In DNA, bases are the adenine base, which only pairs with a thymine
DNA In Criminal Investigation Essay
516 Words | 3 PagesDNA derives from nucleic acids. They store genetic information and transfer energy. DNA is found in the nucleus of eukaryotic cells, and they float around in prokaryotic cells. Covalent linkage bond the DNA molecules together between the phosphate and sugar groups to create a polynucleotide. Two of the polynucleotides are twisted to create the shape of a double helix.

860 Words | 4 PagesThe nucleus is generally in the center of a cell. A typical cell nucleus is so small that ten thousand could fit on the tip of a needle. One strand of DNA is around 6 feet long. This mean that 6 feet of DNA fits inside the nucleus, which occupies about 10% of a total cell (https://en.wikipedia.org/wiki/Cell_nucleus), of a microscopic cell. For this to happen eight separate histone protein subunits attach to the DNA molecule to
DNA Vs Eukaryotes Research Paper
953 Words | 4 PagesThe more that is known about DNA and RNA the better we understand on how it reacts, replicates, and produces proteins in varying environments. With the information that have today we have a rather sufficient grasp on how DNA replicates itself, how DNA produces RNA and vice versa, how RNA replicates itself, and how RNA makes the final product of proteins. Here, we will specifically look at how DNA transcribes into RNA within bacteria and eukaryotes. The main differences between the two transcription process is eukaryotes have a nucleus where the RNA is transcribed and processed while bacteria do not have a nucleus so the RNA is transcribed in the cytoplasm and the RNA is not processed after transcription. They are similar in the fact
DNA In The Inheritance Of DNA
1531 Words | 7 PagesThe role of DNA in the inheritance of genetic traits The Role of DNA in today's society is a something that people have become very common to discuss, yet a number of people don't know its importance in the inheritance of genetic. Mention it in a public area and you might strike a profound discussion as everyone has their own views on their understanding of such a process. The role of DNA is known as the fundamental characteristics that influence a system in this case in the inheritance of genetic traits. Inheritance is the assumption of passing down of traits or characteristic. Genetic traits are referred to as a phenotype an observable trait such as height, eye color, and blood type.

Dna Molecules Research Paper
365 Words | 2 PagesEach DNA molecule is made up of two strands which intertwine to form a double helix. The form of the stucture which looks like a ladder is each nucleotide base is a DNA strand which links with another nucleotide base via hydrogen bonds in a second strand of DNA. The bases cross link in a certain order such as A adenine will only link with T thymine and the other way around then C cytosine will only link with G guanine and the other way around. When reproduction is formed from parents to off spring more genetic materials are needed the 2 stands unzip and enzymes add new bases to each which then form 2 new strands. Different segments of a DNA molecule code for different characteristics in the body.

899 Words | 4 Pages1. What is DNA? DNA i.e. Deoxyribo Nucleic Acid is a material in the human body that determines the hereditary traits of a person pertaining to hair colour, eye colour, skin, body structure, viability to diseases etc. DNA is located in the cells of the human body, wrapped in structures called chromosomes.
Why Is Dna Important
600 Words | 3 PagesThe two strands of the helix are antiparallel and they are connected by the bases thanks to a hydrogen bond. Only adenine can pair up with thymine and only guanine can pair up with cytosine or vice versa. The amount of each base inside every human is almost the same amount (about 3.2 billion bases) but different animals have different amounts. The significance of these amounts is that it determines the information that your body will be able to use to know how to maintain your body. Scientists can use DNA to make exact copies of organisms, called
Why Is DNA Important?
440 Words | 2 PagesDNA The molecules that make up DNA are called nucleotides. These molecules are made up of sugar, a nitrogen base, and phosphate. The nitrogen bases are guanine, adenine, cytosine, and thymine. DNA is a structure that carries genetic material and is present in nearly all living organisms.
