true or false:  During replication, template strands of DNA are read in the 5’ to 3’ direction.

Shown is a sequencing gel. Read the sequence off the gel and determine the first 4 nucleotides (or bases) based on the fact replication occurs 5¹ to 3¹. A I G C Answer:

DNA polymerases are processive, which means that they remain tightly associated with the template strand while moving rapidly and adding nucleotides to the growing daughter stand. Which piece of the replication machinery accounts for this characteristic? Helicase Sliding Clamp Single Stranded Binding Protein Primase

Which of the following processes of genetic information flow can occur under laboratory conditions, but has never been observed to occur under natural conditions (either in living cells or in viruses)? transcription of RNA from a DNA template (using DNA-dependent-RNA-polymerase) self-replication of RNA from an RNA template (using RNA-dependent-RNA-polymerase) direct-translation of protein from a DNA template (using special ribosomes) self-replication of DNA from a DNA template (using DNA-dependent-DNA-polymerase) translation of protein from an RNA template (using ordinary ribosomes)
