What is the restriction site of the restriction enzyme Hae III?
The restriction site of Hae III is GGCC. It cuts between the G and the C. This produces blunt ends.
Why is it important to use the same restriction enzyme for both cells in recombinant DNA?
Restriction enzymes are endonucleases that digest the DNA at a sequence specific site. Hind III for example cut between two As in the sequence AAGCTT in the both strand forming a sticky end. If you use this enzyme to cut in your vector DNA, you have to use the same enzyme in the insert DNA so as they can ligate by DNA ligation. This is the important use of same restriction enzyme in cloning.
What is the DNA pol III?
DNA polymerase III (DNA pol III) is a key enzyme in prokaryotic DNA replication, primarily found in bacteria. It is responsible for synthesizing new DNA strands by adding nucleotides to a growing DNA chain, using the existing template strand as a guide. DNA pol III has high processivity and proofreading capabilities, ensuring accurate and efficient DNA replication. This enzyme operates as part of a larger replication complex, which includes other proteins that help coordinate the replication process.
What enzyme transcribes tRNA in eukaryotes?
The enzyme responsible for transcribing tRNA in eukaryotes is known as RNA polymerase III. It specifically transcribes genes that encode transfer RNAs (tRNAs) as well as other small non-coding RNAs.
What chemical is an enzyme that add nucleotides to a new strand of DNA during replication?
DNA Polymerase is the enzyme which adds new nucleotides during replication.
What is the restriction site of the restriction enzyme Hae III?
The restriction site of Hae III is GGCC. It cuts between the G and the C. This produces blunt ends.
How she was able to add the HInd III restriction enzyme site in this position based on the result of her gel?
She was able to do so because the band pattern portrayed on the agarose gel shows exactly where the sequence AAGCTT was located on the DNA. Because of this, she was able to place the Hind III restriction enzyme right at that sequence since it was given that the enzyme recognizes that specific sequence.

Why the first restriction endonuclease is known as Hind2 and not Hind1?
Restriction enzymes are named based on the organism in which they were discovered. For example, the enzyme Hind III was isolated from Haemophilus influenzae, strain Rd. The first three letters of the name are italicized because they abbreviate the genus and species names of the organism. The fourth letter typically comes from the bacterial strain designation. The Roman numerals are used to identify specific enzymes from bacteria that contain multiple restriction enzymes. Typically, the Roman numeral indicates the order in which restriction enzymes were discovered in a particular strain.There are three classes of restriction enzymes, labeled types I, II, and III. Type I restriction systems consist of a single enzyme that performs both modification (methylation) and restriction activities. These enzymes recognize specific DNA sequences, but cleave the DNA strand randomly, at least 1,000 base pairs(bp) away from the recognition site. Type III restriction systems have separateenzymes for restriction and methylation, but these enzymes share a common subunit. These enzymes recognize specific DNA sequences, but cleave DNA at random sequences approximately twenty-five bp from the recognition sequence. Neither type I nor type III restriction systems have found much application in recombinant DNA techniques.Type II restriction enzymes, in contrast, are heavily used in recombinant DNA techniques. Type II enzymes consist of single, separate proteins for restriction and modification. One enzyme recognizes and cuts DNA, the other enzyme recognizes and methylates the DNA. Type II restriction enzymes cleave the DNA sequence at the same site at which they recognize it. The only exception are type IIs (shifted) restriction enzymes, which cleaveDNA on one side of the recognition sequence, within twenty nucleotides of the recognition site. Type II restriction enzymesdiscovered to date collectively recognize over 200 different DNA sequences.
What are some characteristics of glycogen phosphorylase?
I, II, and III I. It is the rate-limiting enzyme of glycogenolysis II. It breaks alpha 1,4 glycosidic bonds III. It is activated by epinephrine
What are the two different restriction enzymes used to cut the pUC19 plasmid and the lux gene DNA?
Two different restriction enzymes commonly used to cut the pUC19 plasmid are EcoRI and PstI. For cutting the lux gene DNA, the restriction enzymes commonly used are NcoI and HindIII.
Which enzyme is responsible for facilitating the hydrogen bonding between nucleotides in a new molecule?
the DNA polymerase III
Which is the main enzyme used for the replication of DNA in ecoli?
The main enzyme used for the replication of DNA in E. coli is DNA polymerase III. It is a highly processive enzyme that synthesizes new DNA strands by adding nucleotides in a 5' to 3' direction. DNA polymerase III works alongside other enzymes and proteins in the replisome complex to accurately copy the entire genome during DNA replication.
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
What is the prinicpal enzyme involved in DNA replications because it jois individual nucleotides to produce a DN A molecule?
DNA polymerase III .
What enzyme elongates DNA?
DNA polymerase is the main enzyme responsible for elongating DNA strands during DNA replication. It catalyzes the addition of nucleotides to the growing strand in a 5' to 3' direction.
