Answer:
enzymes ARE catalysts molecules made up of amino acids that play a part in speeding up reactions based on their structure
Answer:
Enzymes like DNA polymerase III, HELICASE, Primase, Topoisomerase, ligase.
Explanation:
DNA replication is an important process that must occur prior to cell division. DNA content of a cell becomes duplicated in the process. This process, however, cannot occur without some vital elements that play specific roles. These elements are mostly enzymes which includes DNA polymerase III, HELICASE, Primase, Topoisomerase, ligase.
DNA POLYMERASE III is the main enzyme in this process, it adds nucleotides that are complementary to the unwinded DNA strand in order to synthesize its replica.
However, a new complementary DNA strand cannot be synthesized if the original double-stranded DNA does not unwind or separate. This process of unzipping the DNA into a Y-shaped replication fork is done by HELICASE.
DNA polymerase III starts adding nucleotides from the 3' end of the DNA strand. In order to recognize this end on the strand about to be synthesized, PRIMASE synthesizes a short strand of nucleic acid called Primer. This primer provides the DNA polymerase with something to start working on.
TOPOISOMERASE works on the double-stranded DNA prior to formation of replication fork by helicase. It helps prevent the DNA strands from becoming too tight and super coiled in order to make unzipping easy.
LIGASE helps to fill up those gaps in the DNA fragments during the synthesis of a complementary strand.
Answer:
Conduction: This is a flow of heat by direct contact. Heat travels from a warmer object toward a colder object.
Convection: This is a transfer of heat by mixing a fluid. Convection occurs within liquids and gases. Examples include boiling water and when warm water mixes with cold water.

When the Civil War ended, the big question concerned the state of the freed slaves of the South. Recovery of the southern economy depended on getting the freedmen back into the cotton fields. During the period of Reconstruction the Radical Republicans in Congress tried to convert the freedmen into small free-holding farmers, but the former slaves were simply not ready to manage their own farms. What emerged out of necessity was southern farm tenancy, a system of near slavery without legal sanctions.
Answer: True
Explanation: Cell sends and receives signals from each other. This allows for our body to function correctly. For example your brain cells sends many signals to the rest of the body.
