DNA is called a double-helix because it consists of two strands that spiral around each other. A spiral shape is also called a helix, and there're two of them, so it's a double-helix.

What is the process in which the DNA double helix unfold and each strand serves as a template for the synthesis of a new strand?

The process is called DNA replication. It begins with the unwinding of the DNA double helix by an enzyme called helicase. Each separated strand then serves as a template for the synthesis of a new complementary strand by DNA polymerase.


How does DNA replicate itself when cells divide?

The DNA double helix is unwound and each strand acts as a template for a new double helix.


Each molecule of DNA is called What?

the whole strand is called a double helix a individual molecule made up of... a sugar a phosphate a base is called necleotide.


How many stands make up DNA double helix?

A DNA double helix is made up of two stands that twist around each other in a spiral shape. Each strand consists of a sequence of nucleotide bases that pair up with the bases on the opposite strand, forming the characteristic double helix structure.


What happens after replication?

each new DNA double helix consists of one old strand and one new strand


During dna replication each double helix produced consists of?

During DNA replication, each double helix produced consists of one original parental strand and one newly synthesized daughter strand. The parental strand serves as a template for the synthesis of the complementary daughter strand, resulting in two identical double helices.


Each strand in the double helix is identical to the opposite strand?

No each strand is complementary to the other, not identical. Opposite strands will run in the opposite direction with nucleotides that complement the other strand Ex. 5actgactgactg3 & 3tgactgactgac5


How many bases does a double helix have after the complementary strand is added?

A double helix has twice the number of bases in one strand, so after adding the complementary strand, the double helix will have the sum of the bases in both strands. This is because each base pairs with its complementary base (A with T, and G with C) across the two strands.


What molecule has the shape of a double strand helix?

DNA (deoxyribonucleic acid) has a double helix structure, in which two strands of nucleotides are wound around each other. This helical structure is responsible for carrying genetic information in living organisms.


When DNA replication occurs the enzyme which separates the two side of the helix is called?

The enzyme that separates the two strands of the DNA helix during replication is called helicase. It unwinds the double helix by breaking the hydrogen bonds between the base pairs, allowing each strand to serve as a template for the synthesis of a new complementary strand.


Is DNA a single strand of nucleotides?

No, DNA is a double-stranded molecule composed of nucleotides. Each strand has a specific sequence of four different nucleotides: adenine, thymine, cytosine, and guanine. These two strands are connected by hydrogen bonds to form the double helix structure of DNA.


Is Each strand in the double helix is identical to the opposite strand?

Each strand in the double helix is complementary rather than identical to the opposite strand. The bases in one strand pair up with specific bases in the opposite strand according to the base pairing rule (A with T and C with G). This complementary base pairing allows each strand to serve as a template for the synthesis of a new strand during DNA replication.
