RECOMBINANT DNA

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Functions of modifying enzymes are ____ (The answer can be more than ONE)
A
degradation of nucleic acid
B
synthesis of nucleic acid
C
alteration of nucleic acid
D
isolation of nucleic acid
Explanation: 

Detailed explanation-1: -the modification enzyme ensures that a specific base within the target sequence, one on each strand of the duplex, is methylated and the restriction endonuclease cleaves unmodified substrates within, or close to, the target sequence.

Detailed explanation-2: -Nucleic Acid Modifying Enzymes (ultra pure) In molecular biology labs, these modifying enzymes are commonly used for molecular cloning and sequencing applications. Each enzyme has special characteristics, making it useful for specific applications.

Detailed explanation-3: -Histone modifying enzymes catalyze the addition or removal of an array of covalent modifications in histones and non-histone proteins.

Detailed explanation-4: -They are referred to as DNA Methylases when the primary function of the enzyme is methylation (addition of methyl/alkyl group). They generally catalyze the transfer of methyl groups from S-adenosyl-methionine (SAM) to specific nucleotides of double stranded DNA molecules, e.g., Enzymes part of repair system in E.
