Replication of the lagging strand of dna is accomplished by adding new __________. This creates ______________ on the lagging strand.
Replication of the lagging strand of DNA is accomplished by adding new short RNA primers. This creates Okazaki fragments on the lagging strand.
RNA primers are the short strands of RNA of few nucleotides that are essential to begin the synthesis of DNA at the lagging strand during replication. This primers is synthesized using the enzyme called primase. RNA primers provide the binding site for DNA Polymerase.
Okazaki fragments are the short strands of DNA that are synthesized from the RNA primers. These are discontinuous in nature. In prokaryotes the length of Okazaki fragments can be from 1000-2000 nucleotides, while in the eukaryotes, it can rage only for about 100-200 nucleotides.

Biomolecules contain a variety of atoms. Which biomolecule maintains a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom?.
The biomolecule that maintains a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom is glucose. Glucose is a simple sugar that is a common source of energy for living organisms. It is a six-carbon molecule that contains twelve hydrogen atoms and six oxygen atoms, giving it a chemical formula of C6H12O6.
Glucose is an important biomolecule that plays a central role in metabolism. It is produced by photosynthetic organisms, such as plants and algae, through the process of photosynthesis, where it is synthesized from carbon dioxide and water using light energy from the sun. It can then be stored in the form of glycogen in animals and plants, or converted into other molecules, such as fatty acids or ethanol, for energy storage or other purposes.
Overall, glucose is a biomolecule that maintains a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom, and it plays a crucial role in the metabolism of living organisms.
when a bacterium such as e. coli is shifted from a warmer growth temperature to cooler growth temperature, it might compensate by:
Sixth, a bacteria like E. coli adjusts by inserting long-chain fatty acids into its membrane when it is moved from a warmer to a cooler growing temperature.

Energy is needed for all biological activities, including those in humans and microbes. Many creatures consume other organisms while they are eating in order to acquire stored energy. But from where does the energy that food contains come? The source of all of this energy is photosynthesis. All life on earth depends on photosynthesis; this includes both plants and animals. It is the only biological process capable of converting solar energy, which comes from space, into the chemical molecules (carbohydrates) that every living thing uses to fuel its metabolism.
Only plants, algae, and a kind of bacteria known as cyanobacteria are able to carry out photosynthesis (Figure 1). They are referred to as photoautotrophs, which literally translates to "self-feeders utilizing light," because they produce their own food using light.
