This segment of DNA has undergone a
mutation in which three nucleotides have
been deleted. A repair enzyme would replace
them with
A CGT.
B GCA.
C CTG
D GTA.
I’ll give you the brainliest if you answer with an explanation.
A. CGT
Explain- C pairs with G and A pairs with T. Vise verse.
The correct answer is A CGT. As repair enzyme would replace them with CGT.
The practical section of DNA is known as genes. Gene is the section of DNA that codes for a practical protein. Genes are inherited from mother and father to offspring. They convey genetic statistics from one technology to another.
What are the 4 bases of DNA?
CGT is an acronym for the 4 forms of bases located in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). A DNA molecule includes strands wound around every other, with every strand held collectively through bonds among the bases. Adenine pairs with thymine, and cytosine pairs with guanine.
Hence concluded that CGT is a segment of DNA that has undergone a
mutation in which three nucleotides have been deleted.

other cell structure that is not found in all eukaryotic cells, is likely to be found in this cell?
A. Mitochondria
B. Cell Membrane
C. Cell wall
D. Cytoplasm
The cell wall is found in plant cells but is absent in animal cells. Therefore, option C is correct.
What is a cell wall?Cell walls are a specific type of extracellular matrix that covers every plant cell. Many of the traits that set plant cells apart from animal cells are caused by the cell wall.
Plant cells have a cell wall that surrounds their plasma membrane and offers tensile strength as well as defense against osmotic and mechanical stress. Additionally, it enables the development of turgor pressure or the pressure of the contents of the cell against the cell wall.
The pectin polysaccharide matrix, which is highly cross-linked, contains a matrix of cellulose microfibrils and cross-linking glycans that make up the cell wall. Lignin may accumulate in secondary cell walls. Therefore, option C is correct.
