An enzyme that makes covalent bonds between nucleotide sequences in DNA isGroup of answer choicesRNA polymerase.DNA ligaseDNA helicase.transposase.DNA polymerase.
Solution
The enzyme that makes covalent bonds between nucleotide sequences in DNA is DNA ligase.
Here's a step-by-step explanation:
-
DNA ligase is an enzyme that facilitates the joining of DNA strands together by forming a bond between the phosphate group of one strand and the deoxyribose group on another DNA strand.
-
It is used in cells to join together the Okazaki fragments, which are short sequences of DNA nucleotides, in the lagging strand during DNA replication.
-
DNA ligase can also join together two double-stranded DNA fragments by recognizing the compatible ends and facilitating the formation of phosphodiester bonds.
-
Therefore, DNA ligase is the enzyme that makes covalent bonds between nucleotide sequences in DNA.
The other enzymes listed have different functions. For example, DNA polymerase is responsible for synthesizing DNA by adding nucleotides to the 3' end of a DNA strand. DNA helicase unwinds the DNA double helix during DNA replication. RNA polymerase synthesizes RNA from a DNA template. Transposase is an enzyme that binds to the ends of a transposon and catalyzes the movement of the transposon to another part of the genome.
