Some of these receptors bind to antigens in the blood. The
antigen are then endocytosed and identified. Some of the receptors such as the MHC II are
used in antigen-presentation. They display the antigen for identification and
activation of other lymphocytes.

Answer:
Acids or bases can be tested by chemical indicators.
Explanation:
A chemical indicator can be described as a paper substance which changes colour when dipped in an acidic or basic solution. It can be described as a chemical indicator for hydrogen ions (H+) and hydronium ions (H3O+).
Acidic solutions normally dive red-orange colours depending on the acidicity of the substance. The basic solutions give blue-violets colours depending on the basicity of the substance.
Answer;
GACUG
Explanation;
-Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps.
-First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes. The process relies on Watson-Crick base pairing, and the resultant single strand of RNA is the reverse-complement of the original DNA sequence. The pre-messenger RNA is then "edited" to produce the desired mRNA molecule in a process called RNA splicing.
-The nucleotides pairing follows the same base pairing rules as in DNA to form the correct sequence in the mRNA. However, during transcription, uracil (U) pairs with each adenine (A) in the DNA.
