activation record         
<compiler> (Or "data frame", "stack frame") A data structure containing the variables belonging to one particular scope (e.g. a procedure body), as well as links to other activation records. Activation records are usually created (on the stack) on entry to a block and destroyed on exit. If a procedure or function may be returned as a result, stored in a variable and used in an outer scope then its activation record must be stored in a heap so that its variables still exist when it is used. Variables in the current scope are accessed via the frame pointer which points to the current activation record. Variables in an outer scope are accessed by following chains of links between activation records. There are two kinds of link - the static link and the dynamic link. (1995-03-07)

CRISPR activation         
  • The dCas9-VPR activator increases transcription at the gene that it targets.
  • The use of the Suntag system allows multiple antibodies fused to VP64 to bind to dCas9-Suntag. That in turn recruits RNA polymerase and increases gene expression.
  • The dCas-SAM system uses msgRNA that has attached aptamers for different transcriptional factors (MS2,p65 and HSF1) to bind.
  • Complementary base pairing between the sgRNA and genomic DNA allows targeting of Cas9 or dCas9

CRISPR activation (CRISPRa) is a type of CRISPR tool that uses modified versions of CRISPR effectors without endonuclease activity, with added transcriptional activators on dCas9 or the guide RNAs (gRNAs).

Call stack

In computer science, a call stack is a stack data structure that stores information about the active subroutines of a computer program. This kind of stack is also known as an execution stack, program stack, control stack, run-time stack, or machine stack, and is often shortened to just "the stack". Although maintenance of the call stack is important for the proper functioning of most software, the details are normally hidden and automatic in high-level programming languages. Many computer instruction sets provide special instructions for manipulating stacks.

A call stack is used for several related purposes, but the main reason for having one is to keep track of the point to which each active subroutine should return control when it finishes executing. An active subroutine is one that has been called, but is yet to complete execution, after which control should be handed back to the point of call. Such activations of subroutines may be nested to any level (recursive as a special case), hence the stack structure. For example, if a subroutine DrawSquare calls a subroutine DrawLine from four different places, DrawLine must know where to return when its execution completes. To accomplish this, the address following the instruction that jumps to DrawLine, the return address, is pushed onto the top of the call stack with each call.
