What is DNA replication?

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

What enzyme assembles DNA?

DNA polymeraseFinally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands.

What protein travels down the DNA template strand and assembles complementary strand?

RNA polymerase is the main transcription enzyme. Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule.

Which of the following enzymes is responsible for adding nucleotides to the growing mRNA molecule?

During elongation, an enzyme called DNA polymerase adds DNA nucleotides to the 3′ end of the template. Because DNA polymerase can only add new nucleotides at the end of a backbone, a primer sequence, which provides this starting point, is added with complementary RNA nucleotides.

How is DNA made out of a DNA template?

DNA's unique structure enables the molecule to copy itself during cell division. When a cell prepares to divide, the DNA helix splits down the middle and becomes two single strands. These single strands serve as templates for building two new, double-stranded DNA molecules - each a replica of the original DNA molecule.

What is used as a template in transcription?

DNA is double-stranded, but only one strand serves as a template for transcription at any given time. This template strand is called the noncoding strand.

Which is the process of using a DNA template to make mRNA?

mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.

What is the name of process that uses DNA as a template to make mRNA?

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template.

What is the name of the process that produces RNA from a DNA template?

Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).

What allows each strand of DNA to serve as a template for a new DNA strand during replication?

DNA replication occurs through the help of several enzymes. These enzymes "unzip" DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created. Complementary bases attach to one another (A-T and C-G).

What enzyme is responsible for adding new nucleotides to a growing DNA chain during replication?

DNA polymerasesOne of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template.

What enzyme is responsible for adding nucleotides to a growing nucleic acid during transcription quizlet?

RNA polymerase is the enzyme that builds mRNA on the template of DNA.
