When DNA strands are separated by the enzyme helicase, one of the two strands become the template i.e. free nucleotides from the cytoplasm forming the mRNA runs along this strand and reads the triplet codes by complementary base pairing. The resulting triplet codons of the mRNA, then goes to determine the anticodons and hence amino acid sequencing. Therefore the DNA is responsible for imparting the information for the amino acids to be formed and their sequence, and hence the type of protein.
DNA, is a genetic material present inside the nucleus which has the information that helps in the synthesis of RNA and proteins. They have information which help in the formation of mRNA that specifies a particular protein product. mRNA acts as a template translating DNA code into specific protein. Thus DNA indirectly participates in protein synthesis by taking place in the RNA synthesis
A section of DNA that codes for a given protein is copied (transcripted) onto a mRNA molecule which travels out to a ribosome where translation occurs.
Enzymes play a crucial role in the process of DNA replication by facilitating the unwinding of the DNA double helix, the synthesis of new DNA strands, and the proofreading of the newly synthesized DNA. Enzymes such as helicase unwind the DNA strands, DNA polymerase adds new nucleotides to the growing DNA strand, and exonuclease proofreads and corrects any errors. Overall, enzymes help to ensure that DNA replication is accurate and efficient.
DNA replication requires the aid of enzymes. Enzymes like DNA polymerase and helicase are crucial for unwinding the DNA double helix, synthesizing new DNA strands, and proofreading and repairing any errors that may occur during replication. Without these enzymes, DNA replication cannot proceed effectively and accurately.
Helicase unwinds the double-stranded DNA during replication by breaking hydrogen bonds between base pairs, while topoisomerase helps relieve the tension and supercoiling that occurs ahead of the replication fork by cutting and rejoining the DNA strands. Both enzymes play crucial roles in DNA replication and repair processes, but they have distinct functions and mechanisms of action.
Inhibitors of DNA replication include drugs like Ciprofloxacin and Doxorubicin, which interfere with the enzymes involved in DNA synthesis. These inhibitors disrupt the process of replication by blocking DNA polymerase or topoisomerase enzymes, preventing proper DNA synthesis and cell division. This can be used in cancer therapy to inhibit cell proliferation.
DNA replication is performed by a group of enzymes known as DNA polymerases. These enzymes are responsible for synthesizing new DNA strands by adding nucleotides in a complementary fashion to the existing DNA template. Other proteins are also involved in DNA replication to help unwind the double helix, stabilize the replication fork, and proofread the newly synthesized DNA.
an enzyme called DNA helicases unwinds the double helix before DNA replication begins. enzymes known as DNA polymerases move along each of tge DNA strands while adding nucleotides to the exposed nitrogen bases according to the base pairing rules.
Chromosomes are composed of DNA, which carries genetic information, and proteins, including enzymes, that help organize and regulate the DNA. Enzymes play crucial roles in processes such as DNA replication, repair, and gene expression within the chromosome.

During DNA replication, the enzyme DNA polymerase is primarily responsible for the elongation of the complementary DNA strand. It synthesizes new DNA by adding nucleotides complementary to the template strand in a 5' to 3' direction. Additionally, primase synthesizes a short RNA primer to provide a starting point for DNA polymerase. Other enzymes, such as helicase and ligase, also play crucial roles in unwinding the DNA and joining Okazaki fragments, respectively.

Both enzymes play crucial roles in DNA replication and repair processes, but they have distinct functions and mechanisms of action.
Examples of enzymes in living things include amylase (breaks down carbohydrates), catalase (converts hydrogen peroxide into water and oxygen), and DNA polymerase (involved in DNA replication). These enzymes play crucial roles in various biological processes such as digestion, metabolism, and genetic replication.

DNA replication is aided by enzymes. Without the enzymes DNA will not be able to replicate.There are three main enzymes involved-Helicase - This enzyme separates the two parental DNADNA Polymerase - This enzyme exists in different forms and each one of them have a specific function in the replication of DNA.In short, it enhances each strands, adds base pairs and repairs any damage done to the strands during the replication process.Ligase - This enzyme puts the two stands together after the replication is complete.
