Dna polymerases are a family of enzymes that carry out all forms of dna replication dna polymerases in general cannot initiate synthesis of new strands, but can only extend an existing dna or rna strand paired with a template strand.
Task 1: dna and rna scenario: you are a biochemistry specialist who has been asked to provide information on the role of dna and rna in the transmission of information within the cell. Dna is used as a template to make rna through a process called transcription the rna uses molecular machinery called ribosomes, which use the code to make the amino acids and join them to make polypeptides and proteins.

Structural biochemistry/nucleic acid/dna/replication process from wikibooks, open books for an open world biochemistry | nucleic acid | dna the rna primase's function in dna replication is to lay down rna primers in 3' to 5' fashion. Dna replication: copying genetic information for transmission to the next generation occurs in s phase of cell cycle using an rna template to make dna, telomerase functions as a reverse transcriptase called tert (telomerase reverse transcriptase. Biochemistry questions and answers - dna replication posted on july 17, 2017 by manish this set of biochemistry multiple choice questions & answers (mcqs) focuses on dna replication 1 dna replication is a) conservative biochemistry questions and answers - rna-dependent synthesis. From the department of biochemistry and remains specific even if mismatched nucleotides are present at positions at and near the rna-dna junction 3 this indicates that rnase h1 recognizes the junction and reconstitution of sv40 dna replication with purified proteins showed that.
Because it can perform the tasks of both dna and enzymes, rna is believed to viable daughter cells to be produced would require an extra replication of the intact rna gene homologous to (from peptides) and a rna (from nucleotides) in this peptide-rna world scenario, rna would have. Biochemistry competency 20851: dna, rna - the graduate demonstrates how nucleic acid polymers can transform cells and transmit information within the cell task 1: dna and rna introduction: there is much talk in the news about stem cell research.
