I need help finding the terms of each definition.
1.) The "transforming factor" that alters pneumonia bacteria
2.) The three parts of every nucleotide
3.)A pair of these forms a "rung"in the DNA
4.) Used to "label" DNA and protein in experiments
1.) To find the term for the "transforming factor" that alters pneumonia bacteria, you can search for information on molecules or agents that cause a transformation in the bacteria. One often mentioned term that fits this description is "plasmid". Plasmids are small, circular pieces of DNA that can be transferred between bacteria, allowing them to acquire new traits or properties.
2.) To determine the three parts of every nucleotide, you can recall the basic structure of nucleotides. A nucleotide consists of three components: a sugar molecule (deoxyribose in DNA or ribose in RNA), a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, or thymine in DNA; adenine, guanine, cytosine, or uracil in RNA).
3.) To identify the term for a pair of these that forms a "rung" in DNA, you can think of the structure of DNA. DNA is made up of two strands that are complementary to each other held together by hydrogen bonds. The term you are looking for is "base pair". In DNA, adenine (A) always pairs with thymine (T), while cytosine (C) always pairs with guanine (G). Each pair of these bases forms a "rung" in the DNA double helix.
4.) To find the term used to "label" DNA and protein in experiments, you can look for commonly used methods in molecular biology research. One widely used technique for labeling DNA and proteins is called "fluorescent labeling" or "fluorescent tagging". In this method, fluorescent dyes or tags are attached to specific molecules, allowing them to be easily visualized or detected in experiments.
