DNA REPLICATION - Enzymes and protein DNA primase DNA primase is an enzyme involved in the replication of DNA. DNA primase is, in fact, a type of RNA polymerase which creates an RNA primer (later this RNA piece is removed by a 5' to 3' exonuclease); next, DNA polymerase uses the RNA primer to replicate ssDNA.

DNA polymerase / DNAP DNA polymerase (DNAP) is a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules. Nucleic acids are polymers, which are large molecules made up of smaller, repeating units that are chemically connected to one another.NA is composed of repeating units called nucelotides or nucleotide bases. DNA polymerase is responsible for the process of DNA replication, during which a double-stranded DNA molecule is copied into two identical DNA molecules.

- This association is called lysogeny, and the integrated phage DNA is referred to as a prophage (Figure 6-19). Under certain conditions, the prophage DNA is activated, leading to its excision from the host-cell chromosome and entrance into the lytic cycle. Bacterial viruses of this type are called temperate phages.ome bacterial viruses (bacteriophages) may undergo lysogeny following infection of host cells. In this case, the viral genome is integrated into host-cell chromosomes, forming a prophage that is replicated along with the host genome.

Prokaryotic DNA replication Prokaryotic DNA replication. Prokaryotic DNA replication is the process by which a prokaryote duplicates its entire genome into another copy that is passed on to daughter cells. Although it is often studied in the model organism E. coli, other bacteria show many similarities.

A Brief Guide to Genomics A Brief Guide to Genomics. DNA, Genes and Genomes. Deoxyribonucleic acid (DNA) is the chemical compound that contains the instructions needed to develop and direct the activities of nearly all living organisms. DNA molecules are made of two twisting, paired strands, often referred to as a double helix.

What is the difference between prophage and bacteriophage? A bacteriophage is the whole virus that attacks bacteria and either goes into the lytic direct attack which destroys the bacterial DNA while the phage uses the cell machinery to replicate, or it inserts its own genetic material into the bacterial DNA in the lysogenic cycle becoming a prophage.onfidence votes 22.7K.

How DNA Polymerase and RNA Primase Initiate DNA Replication The RNA primer is a short strand of RNA that initiates DNA replication. So the primer that initiates DNA replication isn't even made out of DNA! Don't get confused about the difference between the RNA primer and the RNA primase. Again, the enzyme that puts together the RNA primer is called RNA primase.

Complementary DNA Output from a cDNA microarray used in testing. In genetics, complementary DNA (cDNA) is double-stranded DNA synthesized from a messenger RNA (mRNA) template in a reaction catalysed by the enzyme reverse transcriptase. cDNA is often used to clone eukaryotic genes in prokaryotes. A eukaryotic cell transcribes the DNA (from genes) into RNA (pre-mRNA). 2  The same cell processes the pre-mRNA strands by removing introns, and adding a poly-A tail and 5’ Methyl-Guanine cap (this is known as post-transcriptional modification). 3  This mixture of mature mRNA strands is extracted from the cell.

Chapter 20 review The prophage may part of the DNA of the host cell for many generations. 4. Influences from the environment trigger the prophage to become active. 5. It then removes itself from the host cell DNA, directs the synthesis of new virus particles, and now becomes an active lytic infection.

- DNA is divided into functional units called genes. A gene (def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA). Since the vast majority of genes are transcribed into mRNA and mRNA is subsequently translated into polypeptides or proteins, most genes code for protein synthesis.The term polypeptide (def) refers to many amino acids (def) connected by peptide bonds (def). gene (def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA).
