How long does DNA replication take? How does RNA polymerase know which strand of DNA to use as template? What is the function of topoisomerase in DNA replication? When does DNA replication occur? How does DNA control the structure of proteins?
What is mRNA? (messenger RNA) Distinguish DNA from RNA, what is the same, what is different? Importance in function? What are the differences between RNA polymerase and primase? How does the transcription of DNA to RNA work? Describe the structure of RNA. RNA types: mRNA, rRNA, tRNA. Ho...
Researchers at Ludwig-Maximilians-Universitaet in Munich, led by Professor Patrick Cramer, have now discovered how the crucial first steps in RNA synthesis are executed -- and gene transcription is initiated.Luise Dirscherl
What is the function of RNA primer? Why is PCR used in the process of DNA sequencing? How does DNA polymerase work? Why is 16S ribosomal RNA variable? How does the base composition of DNA and RNA differ? Explain how both nucleic acids and...

What is DNA and How Does it Work? What Is A Polymerase Chain Reaction? PCR exploits the ability of the polymerase enzymes to create copies of the genetic material under laboratory conditions. Before PCR, copies of DNA were made by isolating a particular DNA fragment and inserting it into the...
In the absence of lactose, the LacI protein binds to the promoter of the lac operon, preventing RNA polymerase (RNAP) from binding. This means that the rest of the lac operon (lacZ, lacY, and lacA) can’t be expressed. Because lactose is not metabolized as easily as glucose, the ...
A subunit of the DNA polymeraseproofreadsthe new DNA. An enzyme calledDNA ligaseseals up the fragments into one long continuous strand. The new copiesautomatically wind up again. Different types of cells replicate their DNA at different rates. Some cells constantly divide, like those in your hai...
