Which of the following is NOT true about DNA?
It is the way that life continues as a genetic connection between generations. |
||
It houses Information in DNA which is the source of form and function. |
||
It determines all of the traits and characteristics that an organism will have. |
||
It's primary function is passed from parent to offspring. |
Deoxyribonucleic acid, or DNA, is a kind of nucleic acid. It refers to the genetic material found in the nucleus.
The nucleotides are the DNA's building blocks.
The nucleotides subunit is made up of the following components:
Deoxyribose is a sugar that is made up of deoxyribose
Phosphate family
Bases containing nitrogen: The nitrogenous bases are divided into four categories. Adenine (A), guanine (G), cytosine (C), and thymine (T) are the four bases (T).

- In the new paradigm, biology is a science based on three levels of molecular information: Biology is a science of information: starting from discovery of DNA and the genetic code, now biologists study how that information is stored, how it is used, and how it evolves. Biologists can take advantage of the same molecular tools to analyze different biological systems, comparing and contrasting the details of information storage and processing that information. Level 1. genetic information is encoded in DNA. Level 2. Biological information is embodied in proteins. What is Level 3? _______________________________ Give your explanation. ____________________________________arrow_forwardAll the genetic variation seen in the human population, passed from generation to generation, arose from mutations that occurred in.. O Somatic (body) cells Reproductive cells (eggs and sperm)arrow_forwardWhich organisms would you predict to have the smallest genomes? O birds O humans O plants bacteriaarrow_forward
- Transposable elements, or jumping genes, are DNA elements that move within the genome. In which organisms are transposons found? Group of answer choices bacteria ancient bacteria all organisms mammals eukaryotesarrow_forwardWhich of the following is the best definition of a molecular marker? a gene that is likely to be associated with a specific disease a dark or light band that on a chromosome that is visible in a karyotype a DNA sequence that varies among individualsarrow_forwardWhat are the properties of genetic material? Must encode information. The information must be used to direct the functioning of cellular processes. The information must be transmissible from generation to generation and from cell to cell. There must be the potential for mutation that can result in the physical variation that exists among individuals and between species. All the above are correct.arrow_forward
- A common misconception about mutations is that they are always harmful. What is the reality of mutation effects on an organism? O Mutations can be harmful, neutral, or beneficial, and they drive genetic variation Mutations are always harmful and decrease genetic variation Mutations are always neutral and have no effect on genetic variation Mutations are always beneficial and increase genetic variationarrow_forwardSome mutations, or changes in the sequence of DNA, do not have any effect on the characteristics of the organism.Why is this?arrow_forwardA graduate student, Dolt Colt, at The Best Western University synthesized a drug called Drug X and noted that it lowered blood cholesterol levels in mice. He tried to see if it works in humans. Is it: Replicability Reproducibility Generalizability Translatability Transparency Rigorarrow_forward
