What chemical element is present in proteins and nucleic acids? What is the genetic code for protein synthesis? What does transcription do in protein synthesis? What is the end product of protein synthesis? What are receptor proteins in the lytic cycle?
What molecule connects the sugars in a strand of DNA? What chemical element is present in proteins and nucleic acids? What type of macromolecule is an enzyme? What five-carbon sugar is found in DNA? A complex carbohydrate consists of repeated units of which of the following? A. Nucleotides ...
Carbon, the central element oforganic compounds, is the second-most abundant element in the human body and contributes roughly 18% of the total body weight. Carbon is the primary element for all life on Earth and is at the base of all organic compounds. Coming in after carbon and fourth o...
Nitrogen is an essential element for life. It is present in all living systems, occurring in several important molecules including proteins and nucleic acids. As a consequence, the origin of the nitrogen cycle and the development and evolution of organisms with the ability to transform nitrogen ...
A. Polycomb response element in the Ubx gene that determines an epigenetically inherited state of repression. EMBO J. 13, 2553–2564 (1994). First report to show that a PRE is required for the transfer of epigenetic memory of transcriptional patterns that are set during embryogenesis in larval...
(1997), where both the stressful conditions and the element (412) were identical. In the first case, an increase of 412 transposition is observed, but not in the second case. The most striking result is that most 412 new sites detected by Ratner et al. (1992) in the F1 of independent...
Among these molecules, harbingers of life, there are amino acids, the base of all proteins found in every living creature. Also in these droplets there are sugars, essential for the construction of DNA.在这些孕育生命的分子中有氨基酸，它是每种生物体内所有蛋白质的基础。在这些液滴中还有糖，它对...
In the past, studies have generally focused on bulk or total element chemistry using sediment cores to follow a lake's history of burden and/or eutrophication. Such analyses give little information about the source of the material or any alteration in its composition over time (e.g., Heathwai...
Nucleotides are the monomers of nucleic acids. A monomer is a single molecule that is linked together many times to form a polymer. Nucleic acid...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
Carbon is the backbone of all biological molecules and life. What could be an alternative element for becoming the most important element in living things? Describe some of the properties of these elements. You have discovered a new substance that you suspect may be a living organism. ...
