They are used in genetic engineering techniques to isolate specific segments of DNA.

. Which of the following statements does not hold true for restriction enzyme. These are not foud in vi ruses. They produce single-stranded complementary ends that can join to two different DNA strands by complementary base pairing.

The bacteria will be unable to host the plasmid. A Most restriction enzymes recognize sequences of 20-25 bp in length. Blunt cutter enzymes produce short overhangs on the DNA after it is cleaved.

They are made by bacteria and viruses. No restriction enzyme is isolated from viruses. QUESTION 4 Which of the following statements is true.

It is an endonuclease. Restriction enzymes cut DNA randomly. They are present in bacteria to provide a type of defense mechanism called the restricition modification system and the so called system consist of two component restriction enzymes and.

C It is isolated from viruses. It is isolated from viruses. Which of the following statements does not hold true for restriction enzyme.

The restriction enzymes are called molecular scissors and are responsible for cutting DNA on specific sites. A It recognizes a palindromic nucleotide sequence b It is an endonuclease c It is isolated from viruses d It produces the same kind of sticky ends in different DNA molecules. They are made by bacteria and viruses.

It is an endonuclease C. Which of the following statements does not hold true for restriction enzyme. Restriction enzymes are produced by bacteria to restrict the growth of bacteriophage in them.

It recognises a palindromic nucleotids sequence. The first restriction endonuclease Hind II was isolated from bacteria Haemophilus influenza they identify a specific palindromic sequence and makes a cut within the specific recognition sequence. It can be used at higher temperatures.

More than 900 restriction enzymes have been isolated from over 230 strains of basteria each of which recongnise different recongition sequences. Restriction enzymes recognize specific sequences on DNA and always cuts so that only blunt ends are produced. It produces the same kind of sticky ends in different DNA molecules.

They are made by only bacteria not viruses. In the bacterial cell restriction enzymes cleave foreign DNA thus eliminating infecting organisms. Hundreds of different ones have been isolated and purified.

Correct option is C Restriction enzymes are endonucleases that cleave phosphodiester bonds in the DNA backbone. A It recognizes a palindromic nucleotide sequence. B It is an endonuclease.

A A given restriction enzyme always recognizes the same DNA sequence and will cut identically regardless of the species of origin of the DNA. Which of the following statements not true for restriction enzyme which is used in genetic engineering. Hundreds of different ones have been isolated and purified.

C they produce single-stranded complementary ends that can join to two different DNA strands by complementary base-pairing. D Restriction enzymes may produce either sticky or blunt ends when digesting host DNA. The plasmid will contain the human gene.

These enzymes are isolated from prokaryotic bacterial cells. Restriction enzymes can be used to compare different genomes based on the produced pattern of DNA fragments. Which of the following statements does not hold true for restriction enzyme.

C All restriction enzymes make blunt ends at their recognition sites. Which of the following statements concerning restriction enzymes are true. All of the following statements are true about restriction enzymes EXCEPT A they are made by bacteria and viruses.

The plasmid will not contain the human gene. All of the following statements are true about restriction enzymes EXCEPT. The bacterial DNA will not be cut open by the restriction enzyme.

Correct option is A Restriction enzymes cut DNA strands by identifying specific sequences of nucleotides. B Bacteria can add methyl groups to their DNA to prevent digestion by endogenous restriction enzymes. It recognises a palindronic nucleotide B.

It produce the same kind of stickly ends in different DNA molecules. The restriction enzymes or restriction endonuclease are called molecular scissors and they are responsible for cutting DNA on specific sites. Restriction enzymes are enzymes which have the ability to recognize and cut a particular sequence of DNA.

C Most restriction enzymes recognize palindromic sequences in host DNA. NCERT DC Pandey Sunil Batra HC Verma. The restriction enzyme will be unable to cut the human DNA.

These enzymes recognizes a palindromic sequence of nucleotide ie a sequence which makes the same word when read forward and backward. It is isolated from bacteriophages D. Restriction enzymes bind as dimers on a palindrome DNA sequence.

D It produces the same kind of sticky ends in different DNA molecules. Most restriction enzymes recognize sequences of 20-25 bp in length. All of the following statements are true about restriction enzymes EXCEPT A.

These are obtained from bacteria Example EcoRI. B hundreds of different ones have been isolated and purified. Sequences of DNA that are recognized by restriction enzymes are called recognition or restriction sites are usually are between 4 and 8 bases long.

They produce single-stranded complementary ends that can join to two different DNA strands by complementary base pairing. The correct answer was given. It produces sticky ends.

Bacteria are not digested by the endonucleases they produce because they lack the binding sequence in their genome. They can be found in bacteria which provide a type of defence mechanism called the restriction modification system and the so-called process consists of two component restriction enzymes and modification enzymes. Which of the following statements does not hold true for restriction enzyme.

Which of the following statements does not hold true for restriction enzyme. Restriction enzymes that perform staggered cuts are more important for the application of recombinant DNA technology compared to restriction enzymes that perform straight cuts because. It is an endonuclease.
