Match the following enzymes involved in DNA replication with their functions.
spin [16.1K]

Answer:

DNA ligase is an enzyme which can connect two strands of DNA together by forming a bond between the phosphate group of one strand and the deoxyribose group on another.

DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, which are the building blocks of DNA. The enzymes play an essential role in DNA replication, usually working in pairs to produce two matching DNA stranges from a single DNA molecule.

DNA gyrase is an essential bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA

Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. There are DNA and RNA helicases. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.

To test the hypothesis that a particular plant synthesizes storage lipids by using glyceraldehyde 3-phosphate (G3P) from photosy
Nookie1986 [14]

Answer:

Radiolabeled carbon atom in CO2

Explanation:

Photosynthesis is the process by which green plants fix the atmospheric CO2 into glucose. The process includes carbon fixation during which RuBisCo enzyme catalyzes the reaction of CO2 and a five-carbon compound called RuBP to form 3-phosphoglycerate (3-PGA). The 3-PGA enters the reduction phase of the Calvin cycle wherein it is reduced into glyceraldehyde 3-phosphate. Two molecules of glyceraldehyde 3-phosphate make one molecule of glucose.

To test the hypothesis that glyceraldehyde 3-phosphate from photosynthesis is used by plants to synthesize lipids, radiolabeled CO2 must be used. The radiolabeled carbon atom in the CO2 would be fixed in the form of glyceraldehyde 3-phosphate. If the plant uses glyceraldehyde 3-phosphate as a precursor for lipid synthesis, the synthesized lipid molecules would carry the radiolabeled carbon atom.

When glycolysis produces pyruvic acid faster than it can be used by the mitochondria, the pyruvic acid is converted to _________
nikdorinn [45]

Answer:

<h2>lactic acid</h2>

Explanation:

Glycolysis is the process of the breakdown of glucose by enzymes, and the energy production in the cell. It occurs in all cell in all organism. Through glycolysis, there is the production of ATP and NADH, which are used in energy requirement. Glycolysis occurs in cytosol, with the help of various enzymes, like hexokinase, phosphofructokinase and PEP etc. When glycolysis produces pyruvic acid faster than it can be used by the mitochondria, the pyruvic acid is converted to lactic acid.
