18. Which enzyme is responsible for creating the covalent bonds that connect the sugar-phosphate backbone of the new DNA molecules?
The enzyme responsible for creating the covalent bonds that connect the sugar-phosphate backbone of new DNA molecules is called DNA ligase. During DNA replication and repair, DNA ligase catalyzes the formation of phosphodiester bonds between adjacent nucleotides, sealing any gaps in the backbone. This ensures the integrity and continuity of the DNA molecule.
What are the molecules that make the 'upright' of the ladder?
The "upright" of the ladder in the structure of DNA refers to the sugar-phosphate backbone. This backbone is composed of alternating sugar molecules (deoxyribose in DNA) and phosphate groups. These molecules are held together by covalent bonds, creating a stable structure that supports the genetic information encoded in the nitrogenous bases attached to the sugars.
Do guanine always pair with adenine?
They pair by hydrogen bonds holding them together. Covalent bonds hold the nucleotides together, creating a sugar-phosphate backbone.
How are the backbones of DNA held together?
The backbones of DNA are held together by covalent bonds, specifically phosphodiester bonds. These bonds form between the phosphate group of one nucleotide and the sugar group of another nucleotide, creating a strong polymer structure that makes up the backbone of the DNA molecule.
What type of bond that holds molecule?
Covalent bonds hold molecules together by sharing electrons between atoms. Ionic bonds form when atoms transfer electrons to each other, creating electrically charged ions that are attracted to one another.

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.

What is the representative unit of a covalent compound?
The representative unit of a covalent compound is a molecule. In covalent compounds, atoms share electrons to form covalent bonds, creating discrete units known as molecules. These molecules represent the smallest unit of a covalent compound that retains the properties of that compound.
Where are covalent bonds located in a DNA molecule?
Covalent bonds in a DNA molecule are located in the sugar-phosphate backbone that runs along the sides of the molecule. These covalent bonds link the phosphate group of one nucleotide to the sugar group of the next nucleotide, creating a strong and stable backbone for the DNA molecule.
What chemical bonding does vinegar have?
Vinegar, which is primarily composed of acetic acid, contains covalent bonding. Covalent bonding involves the sharing of electron pairs between atoms, creating stable molecules.
What type of bonding does candle wax have?
Candle wax typically has covalent bonds holding its molecules together. These bonds form between the atoms within the molecules of the wax, creating a stable structure that gives the wax its characteristic properties.
Do all polar molecules contain polar covalent bonds?
Yes, polar molecules contain polar covalent bonds. A polar covalent bond is formed when atoms with different electronegativities share electrons unevenly, creating a partial positive and partial negative charge. These charges result in an overall dipole moment for the molecule, making it polar.
Why do simple covalent molecules have a smell?
Simple covalent molecules have a smell because they can bind to receptors in our nose, triggering a signal to the brain that we interpret as a smell. Different molecules bind to different receptors, leading to a variety of smells. The specific shape and chemical properties of the molecule determine which receptors it can bind to, creating the perception of smell.
How do ATP molecules provide energy for cellular activities?
ATP molecules provide energy for cellular activities by releasing energy when the phosphate group is broken off, creating ADP and a phosphate molecule. This energy release powers various cellular processes, such as muscle contraction, protein synthesis, and active transport.
What type of bond does to oxygen diatomic molecules use?
Oxygen diatomic molecules use a covalent bond to share electrons and form a stable molecule. Each oxygen atom contributes one electron to the shared bond, creating a double covalent bond between the two atoms.
Which molecules are responsible for creating a chemiosmotic gradient?
Protons (H+) are the main molecules responsible for creating a chemiosmotic gradient across biological membranes. In cellular respiration, the electron transport chain pumps protons across the inner mitochondrial membrane, creating a gradient that drives ATP synthesis through ATP synthase.
