What else can I help you with?
The enzyme that restores the phosphodiester linkage between adjacent fragments in the lagging strand during DNA replication is?
DNA ligase. It plays a crucial role in DNA replication by creating a phosphodiester bond between the Okazaki fragments in the lagging strand to complete the DNA synthesis process.
What enzyme links DNA nucleotides to a growing daughter strand?
DNA polymerase is the enzyme that links DNA nucleotides to a growing daughter strand during DNA replication. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides on the new DNA strand.
What is the role of DNA ligase in the enlogation of the lagging strand during DNA replication?
DNA ligase plays a crucial role in the elongation of the lagging strand during DNA replication by sealing the nicks between the Okazaki fragments. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides, joining the fragments together to form a continuous strand. This ensures the completion of the synthesis of the lagging strand and the formation of a fully functional double-stranded DNA molecule.
What bonds form a polynucleotide strand?
A polynucleotide strand forms from covalent bonds known as phosphodiester bonds, which link together the individual nucleotides (composed of a sugar, phosphate group, and nitrogenous base). These phosphodiester bonds connect the 3' carbon of one nucleotide to the 5' carbon of the next nucleotide in the strand, creating a linear chain.
What does photolyases do to thymine diamers?
Photolyases repair thymine dimers by using visible light energy to break the covalent bonds formed between adjacent thymine bases in the DNA strand. This process, called photoreactivation, restores the original structure of the DNA molecule by splitting the thymine dimer back into individual thymines.
The enzyme that restores the phosphodiester linkage between adjacent fragments in the lagging strand during DNA replication is?
DNA ligase. It plays a crucial role in DNA replication by creating a phosphodiester bond between the Okazaki fragments in the lagging strand to complete the DNA synthesis process.
What type of chemical bond holds together the backbone of a strand of DNA?
Covalent bonds between a sugar molecule (deoxyribose) and a phosphate group make up the backbone of DNA. These are very strong covalent bonds and are broken only with great expenditure of energy--x-rays, for example.
Which enzyme is responsible for creating the covalent bonds that connect the sugar-phosphate backbone of the new DNA molecule?
DNA ligase is the enzyme responsible for creating the covalent bonds that connect the sugar-phosphate backbone of the new DNA molecule during DNA replication and repair processes. It seals the nicks between adjacent nucleotides to form a continuous DNA strand.
Covalent bonds between the sugar of one nucleotide and the of the next nucleotide bond nucleotides together in a DNA strand.?
Actually, it is the phosphodiester bonds that connect the sugar of one nucleotide to the phosphate group of the next nucleotide in a DNA strand, forming the backbone of the DNA molecule. Covalent bonds between the nitrogenous bases help to stabilize the double helix structure of DNA.
What enzyme links DNA nucleotides to a growing daughter strand?
DNA polymerase is the enzyme that links DNA nucleotides to a growing daughter strand during DNA replication. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides on the new DNA strand.
What is the molecule that seals the gaps between the pieces of DNA in the lagging strand is?
The molecule that seals the gaps between the pieces of DNA in the lagging strand is DNA ligase. DNA ligase is an enzyme that catalyzes the formation of phosphodiester bonds between adjacent DNA fragments, joining them together to create a continuous strand.
What is the role of DNA ligase in the enlogation of the lagging strand during DNA replication?
DNA ligase plays a crucial role in the elongation of the lagging strand during DNA replication by sealing the nicks between the Okazaki fragments. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides, joining the fragments together to form a continuous strand. This ensures the completion of the synthesis of the lagging strand and the formation of a fully functional double-stranded DNA molecule.

These phosphodiester bonds connect the 3' carbon of one nucleotide to the 5' carbon of the next nucleotide in the strand, creating a linear chain.
What is the enzyme that correctly attaches new nucleotides to the open strand of the DNA called?
The enzyme responsible for attaching new nucleotides to the open strand of DNA is called DNA polymerase. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides on the growing DNA strand during DNA replication.
What are the bonds found in DNA molecules?
The bonds found in DNA molecules are hydrogen bonds between complementary nitrogenous bases (adenine-thymine and guanine-cytosine) and phosphodiester bonds between the sugar and phosphate groups of adjacent nucleotides in the backbone of the DNA strand.
What types of linkage joins the nucleotides a within a single DNA strand and b between two single DNA strands?
a. Phosphodiester bonds link nucleotides within a single DNA strand. b. Hydrogen bonds link complementary base pairs between two single DNA strands.
How are nucleotides in a single strand of a DNA molecule linked together?
Nucleotides in a single strand of a DNA molecule are linked together by strong chemical bonds called phosphodiester bonds. These bonds connect the sugar and phosphate groups of adjacent nucleotides, forming a long chain that makes up the DNA molecule.
