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.
How is DNA made in your bodies?
DNA is made in the body through a process called DNA replication. This involves the separation of the two strands of DNA, followed by the synthesis of two new complementary strands using the existing strands as templates. The enzyme DNA polymerase plays a key role in catalyzing the formation of new DNA strands.
The DNA molecule is usually made up of how many strands?
The DNA molecule is typically made up of two strands that are arranged in a double helix structure. Each strand consists of a series of nucleotides that pair up based on complementary base pairing (A with T, C with G).
What is the wire made of many strands?
Wire made of many strands is 'cable'
How many strands is DNA made of?
DNA is made of two strands that run in opposite directions and are held together by hydrogen bonds between complementary base pairs (adenine-thymine and guanine-cytosine). This structure forms the famous double helix shape of DNA.
which best describes the structure of dna molecule?
Answer:Two strands of DNA link together
How many strands are there in DNA?
DNA is made up of two strands.
What is one feature of all DNA molecules is that they are?
One feature of all DNA molecules is that they are composed of two strands that form a double helix structure. These strands are made up of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base. The specific sequence of these bases encodes genetic information, and the two strands are held together by complementary base pairing. This structure is fundamental to DNA's role in heredity and cellular function.
How many sides does DNA have?
DNA is often described as having a double-helix structure, which means it consists of two intertwined strands. Each strand has a backbone made of sugar and phosphate groups, while the rungs of the helix are made up of nucleotide base pairs. Therefore, while DNA itself doesn't have "sides" in the traditional sense, it can be thought of as having two complementary strands that run in opposite directions.
Which would you expect to be more viscous a polymer made of long molecular strands or one made of short molecular strands?
A polymer made of long molecular strands would generally be more viscous than one made of short molecular strands. Longer molecular chains lead to more entanglement and interactions between chains, resulting in higher viscosity.
What does it mean to say DNA polymerase reads a template strand to make the complementary strand?
During DNA replication, the enzyme DNA polymerase catalyses the formation of new strands of DNA, using the old strands as models. DNA has a double-helix structure, with two strands forming each helix. Each strand is made up of DNA nucleotides, with the genetic information encoded in the sequence of different nucleotides (different nucleotides are distinguished by molecules called 'bases' attached to them, so the sequence of nucleotides is known as the 'base sequence'). The base sequence of one strand is complementary to that of its' neighbour - the base A binds with T, and C with G, so if one strand had the sequence ATTACA, the base sequence of the complementary strand would be TAATGT. When DNA polymerase creates a new DNA strand, it does so by matching nucleotides to the base sequence of one of the strands - the template strand. New nucleotides are brought in, which match the template in a complementary fashion (ie. A-T, C-G), and join to become one new strand. This new strand is complementary to the template.
What best describes the structure of a DNA molecule?
A DNA molecule is a double helix structure made up of two strands that are composed of nucleotides. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). The bases on the two strands bond together in a complementary way (A pairs with T, and C pairs with G).
