How does a single DNA molecule produce two identical molecules?
Two single chains bond together. The bonded chains twist together to form a double helix.
What are the two long chains in the DNA called?
The two long chains in DNA are called nucleotide strands. These strands are made up of smaller units called nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base. The nucleotide strands are complementary and form a double helix structure.
Why do cells need to separate?
Only some cells separate. Ones that normally are only one cell will do that. Some cells form two cells, some form strands or chains, and some form clusters and look like a bunch of grapes. In other situations, many cells together will form tissues. These are found in animals and plants. It really depends on how their genes work and tell them what to do.
Do nucleotides form polymers?
Yes, nucleotides form polymers called nucleic acids. Nucleic acids are long chains of nucleotides that are essential in storing and transmitting genetic information. DNA and RNA are examples of nucleic acids formed by nucleotide polymers.
What is the definition of DNA molecule?
Consists of two polynucleotide chains in the form of a double helix, containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine
What species form long chains and their cell form a helix?
Desmidium swatzii
What species stay together and form chains what they form?
zigzag patterns

What form chains with overlapping ends are dead when mature?
Water-conducting cells
What shape is DNA and how is it stored in cells?
DNA is shaped like a double helix. It is stored in cells in the form of chromosomes, which are long strands of DNA wrapped around proteins called histones. These chromosomes are organized in the cell's nucleus.
How are the two chains of a double helix held together?
The two chains of a DNA double helix are held together by hydrogen bonds between complementary base pairs. Adenine pairs with thymine, and cytosine pairs with guanine. These hydrogen bonds form the base pairs that hold the two strands of DNA together.
What are the sequences of how cells form into species?
Cells--tissues--organs and organ systems---organisms.
What type of helix is found in DNA?
The type of helix found in DNA is a double helix. This structure consists of two strands that twist around each other to form a helical shape. Each strand is made up of nucleotides that are connected by hydrogen bonds.
