What is DNA replication and what does it produce?
A protein that is known as Helicase attaches to and breaks apart the hydrogen bonds that are between the bases on the DNA strands. Then it pulls the helix apart. DNA just works as a template to make mRNA (messenger RNA)
What is the DNA Replication?
DNA replication is the process in which the hydrogen bonds between the two strands of DNA are broken and then new DNA nucleotides are bonded along each strand according to the base-pairing rule. The result is two identical molecules of DNA.
At the end of DNA replication two new strands of DNA have been produced giving a total of?
Two new DNA chains are formed at the end of DNA replication, both identical in sequence to the template (or parent) chain. These chains are composed of 2 complimentary strands. It is important to note that of the newly formed DNA chains, one strand is the same as the template strand and the other one is a newly synthesized one.
What is the process by which a DNA molecule is copied called?
The process by which a DNA molecule is copied is called DNA replication. During DNA replication, the two strands of the double helix separate and each strand serves as a template for the synthesis of a new complementary strand. This results in two identical copies of the DNA molecule.
What is the role of helicase and DNA polymerase in DNA replication?
Helicase unwinds the double-stranded DNA molecule, separating the two strands. DNA polymerase then adds complementary nucleotides to each strand, creating two new identical DNA molecules.
The two DNA strands that form during mitosis are identical true or false?
True and false because two DNA strands can be Identical during mitosis sometimes and sometimes not.
How many strands of DNA did you start with and end with?
we started with a single strand DNA molecule.
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
When a DNA molecule replicates are the 2 new strands identical?
Yes, they both are [all but] Identical.
What holds the two strands of DNA to each other?
hydrogen bonds
Are DNA complimentary strands alike?
no these are complementary to each other not alike.
What holds the strands of a DNA molecule to each other?
Hydrogen bonds
Which process must occur before mitosis and meiosis produces two identical DNA strands from one original templates and uses DNA polymerase enzyme to produce the copy?
DNA replication must occur before mitosis and meiosis can produce two identical DNA strands from one original template. During DNA replication, the DNA molecule unwinds and separates into two strands, each serving as a template for the synthesis of a new complementary strand. This process is carried out by DNA polymerase enzymes and results in the formation of two identical DNA molecules.
How do DNA expand?
DNA expands through a process called replication, where the double-stranded DNA molecule separates into two strands, and each strand serves as a template for the synthesis of new complementary strands. Enzymes known as DNA polymerases add nucleotides to the growing new strands, resulting in two identical DNA molecules.
What holds two strands of dna molecule to each other?
The two strands of DNA are held together by hydrogen bonds between the nitrogen base pairs.
What end product is formed during replication?
two identical strands of DNA
What holds two strands of a DNA molecules to each other?
hydrogen bonds
