How does DNA determine the traits of an organism?
DNA contains the information to make proteins, which carry out all the functions and characteristics of living organisms. DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein.
How is DNA translated into traits?
It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.
What is the relationship between traits and DNA?
The traits of a living thing depend on the complex mixture of interacting components inside it. Proteins do much of the chemical work inside cells, so they largely determine what those traits are. But those proteins owe their existence to the DNA (deoxyribonucleic acid), so that is where we must look for the answer.
What determines which trait your snork gets?
Snorks only have one chromosome with 6 genes on it. Your job is to analyze the genes of its DNA and determine what traits the organism has….
| Amino Acid Sequence | Trait |

What is a snork in biology?
Snorks were discovered on the planet Dee Enae in a distant solar system. Snorks only have one chromosome with eight genes on it. Your job is to analyze the genes of its DNA and determine what traits the organism has and then sketch the organism (You can be creative here).
What is the role of DNA in determining an organism’s traits quizlet?
Explanation. DNA contains the genes or the genetic material of an organism. Its role is to store information that are essential in controlling the genetic makeup or producing a certain characteristic of an organism.
What is determined by DNA?
The sequence of the bases?, A, C, G and T, in DNA determines our unique genetic code and provides the instructions for producing molecules in the body. The cell reads the DNA code in groups of three bases.
How does DNA determine A trait such as eye color of an organism?
Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.
What determine your trait?
Traits can be determined by genes, environmental factors or by a combination of both. Traits can be qualitative (such as eye color) or quantitative (such as height or blood pressure). A given trait is part of an individual's overall phenotype.
How is your DNA determined?
Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.
How does DNA determine a trait such as eye color of an organism?
Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.
How does the DNA hold the code for making proteins?
Each gene's code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T) — in various ways to spell out three-letter “codons” that specify which amino acid is needed at each position within a protein.
What is amino acid sequence?
Listen to pronunciation. (uh-MEE-noh A-sid SEE-kwents) The arrangement of amino acids in a protein. Proteins can be made from 20 different kinds of amino acids, and the structure and function of each protein are determined by the kinds of amino acids used to make it and how they are arranged.
Where does the transcription take place?
nucleus The process of Transcription takes place in the cytoplasm in prokaryotes and in nucleus in eukaryotes. It uses DNA as a template to make an RNA (mRNA) molecule. During transcription, a strand of mRNA is made that is complementary to a strand of DNA .
How does DNA determine traits quizlet?
DNA carries the instructions for making all proteins, which determine our traits. DNA can't leave the nucleus so mRNA copies the message of DNA and carries it to a ribosome. On the ribosome mRNA is read by tRNA, which brings in the correct amino acid to make the protein. This protein will determine a trait.
What traits do genes determine?
Genes (say: jeenz) play an important role in determining physical traits — how we look —and lots of other stuff about us. They carry information that makes you who you are and what you look like: curly or straight hair, long or short legs, even how you might smile or laugh.
What determines DNA?
DNA? provides instructions for making proteins? (as explained by the central dogma?). The sequence of the bases?, A, C, G and T, in DNA determines our unique genetic code and provides the instructions for producing molecules in the body.
How does DNA contain information?
DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base—A, C, T, or G—can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.
What does your DNA determine?
DNA? provides instructions for making proteins? (as explained by the central dogma?). The sequence of the bases?, A, C, G and T, in DNA determines our unique genetic code and provides the instructions for producing molecules in the body.
How does DNA hold information?
DNA stores biological information in sequences of four bases of nucleic acid — adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix.
What is protein synthesis?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
What is a polypeptide a sequence of what kind of bond holds this sequence together?
When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on the interactions (dashed lines) between its amino acid side chains.
What is this step of transcription transpires when the enzyme RNA polymerase?
Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ''read'' the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases.
What begins the process of transcription RNA polymerase proteins repressor genes?
The Transcription Process. The process of transcription begins when an enzyme called RNA polymerase (RNA pol) attaches to the template DNA strand and begins to catalyze production of complementary RNA.
What determines the traits of an organism quizlet?
The traits of an organism are determined by its genes. 2. Each organism has two alleles that make up the genotype for a given trait. 3.
Which part of the DNA molecule determines an organism’s traits quizlet?
A "Gene" is a segment of DNA that codes for a protein, which in turn codes for a trait (skin tone, eye color..etc), a gene is a stretch of DNA.
How do genes determine the traits of an organism explain in detail quizlet?
Explanation. DNA is a molecule that contains the whole genetic code of an organism. Based on nucleotide sequences of these genes, particular proteins are made in ribosomes of a cell. Proteins affect the function of a cell on a molecular level, which causes a certain characteristic to develop.
How does the DNA work?
DNA's unique structure enables the molecule to copy itself during cell division. When a cell prepares to divide, the DNA helix splits down the middle and becomes two single strands. These single strands serve as templates for building two new, double-stranded DNA molecules – each a replica of the original DNA molecule.
What is DNA short answer?
Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix.
