Question

in 1st step of V(D)J recombination, one RAG complex binds one type of RSS and another complex binds second type of RSS; interaction between two RAG complexes __

Answer 1

In the first step of V(D)J recombination, two RAG complexes bind to different RSS sequences. Their interaction brings the RSS sequences close together to initiate the DNA cutting and rearrangement process.

Step-by-step explanation:

In the first step of V(D)J recombination, one RAG complex binds one type of Recombination Signal Sequence (RSS) and another RAG complex binds the second type of RSS. The interaction between the two RAG complexes is important for the process of recombination. The RAG complexes bring the RSS sequences close together to initiate the DNA cutting and rearrangement process. This interaction allows for the joining of different gene segments and contributes to the generation of diverse antibodies in B cells.
