DNA replication is the process of formation of a new DNA strand from the parent strand by the use of certain enzymes such as polymerases, ligases, and topoisomerases. DNA replication takes place in the nucleus of the cell.Answer and Explanation: DNA rep...
Describe the process of DNA replication. Explain what all DNA repair systems (except proofreading) have in common. Describe the steps involved in nucleotide excision repair. (a) What are the different types of DNA repair? (b) How do they repair the damage?
(a)Compare between DNA replication and transcription.Similarities1. Both involve unwinding of the double helix DNA;2.Both involve breaking of the weak hydrogen bonds between complementarbases;3.Both involve formation of phosphodiester bonds between neighbouring nucleotides;4.Both involve aligning free nucl...
The origins of eukaryotes are more complex than those of prokaryotes because the initiation of DNA replication and the control of the growth cycle of the organism are regulated and co-ordinated at these sites. () 2. Minichromosomes are applied widely to study initiation mechanism of DNA replicati...
WEISSMAN (Dept. Hum. Genet., Yale Univ., CT) To isolate factors involved in accurate initiation of transcription of the human /~- globin gene, HeLa cell nuclear extract was subject to two successive chromatographic steps. On an anion exchange high performance liquid chromatography (HPLC) column...
HIV-1 integrase(IN) is one of three viral enzymes required for replication. IN mediates integration of viral DNA into the host genome in two steps: 3′-processing and strand transfer. It is currently recognized as an important target for therapeutic development against AIDS. QSAR (Quantitative ...
