The correct answer is "early in b cell development, recombinase links one light-chain v gene segment to one j gene segment".
Recombinase is an enzyme whose function is genetic recombination. There are many different types of recombinase and one of these is the V(D)J recombination. This is a recombination occurring in developing lymphocytes during the beginning of the maturation of T and B cells. V(D)J recombination involves somatic recombination and its basis is the random rearrangement of variable (V), joining (J) and diversity (D) gene segments. This process ensures the lymphocyte diversity seen in all the different types of antibodies and T cell receptors found on B and T cells.
The four sensations detected by the tactile receptors in the skin are touch, pressure and vibration and tickle.
<h3>What are the 4 sensations that the receptors found in the skin have?</h3>
They are nerve endings formed by a branched axon. They are distributed in almost all parts of the body and capture mechanical (pressure), thermal (cold and heat) and especially painful sensations.
This is because Tactile sensations are the ones that detect touch, pressure, and vibration. About six different types of tactile receptors are known.

Photosynthesis occurs in the Chloroplasts.
The respiration takes place in the Mitochondria.
Hope this helps!! :)
Active transport is the movement of all types of molecules across a cell membrane against its concentration gradient.
Answer:
5'UAGCGAGG3'
Explanation:
RNA does not have the Thymine base. Instead, its place is was taken by Uracil. Therefore during transcription, an Adenine on the DNA is paired with a Uracil on the RNA. Uracil can, nonetheless, also be formed by deamination of Cytosine resulting in mutation due to mismatched base pairing during replication.
