What scientist first developed rules about base composition?
Erwin Chargaff, an Austrian biochemist, first developed rules about base composition in DNA in the early 1950s. Chargaff's rules stated that the amount of adenine is roughly equal to thymine, and the amount of guanine is roughly equal to cytosine in DNA molecules.
Formed by joining DNA molcules from two different organisms?
recombinant DNA
What formed by joining DNA molecules from two different organisms?
recombinant DNA
What scientist first developed rules about base composition that allow one to calculate the expected amount of each base?
The scientist who first developed rules regarding base composition in DNA was Erwin Chargaff. Chargaff's rules state that in a double-stranded DNA molecule, the amount of adenine (A) equals that of thymine (T), and the amount of cytosine (C) equals that of guanine (G). This foundational work laid the groundwork for understanding the base pairing in DNA and contributed to the discovery of the double helix structure by Watson and Crick.
Name the enzyme joining Okazaki fragments?
DNA ligase is the enzyme that is responsible for joining Okazaki fragments on the lagging strand during DNA replication. It catalyzes the formation of phosphodiester bonds between the fragments, sealing the gaps in the newly synthesized DNA.
What is last step in the production of a recombinant DNA plasmid?
The last step in the production of a recombinant DNA plasmid is joining the DNA. This is done by adding DNA ligase to joint DNA fragments.
What 2 scientist developed a model of DNA?
James Watson and Francis Crick developed the double helix model of DNA in 1953.
What is the function of the enzyme DNA ligase?
DNA ligase is an enzyme that plays a crucial role in the process of DNA replication and repair by joining together the ends of DNA strands to form a continuous strand.
What Is responsible for joining two individual DNA strands together to form the final DNA molecule?
The newly created DNA strand binds to the parent DNA strand with the help of ligase enzyme.
What enzyme is used to join DNA nucleotides?
In DNA replication, DNA polymerase III is the enzyme which joins the DNA nucleotides together via phospodiester bonds.DNA Ligase is the enzyme that seals gaps in DNA during DNA Replication.DNA Ligase is the enzyme that seals gaps in DNA during DNA Replication.
How did the rules of rugby develop?
The rules have developed significantly since 1837. The rules are now openly avaiable on line at the IRB site and include reviewed rules and those that are being developed through actual trial play.
Why was loac developed?
to provide rules of engagement
