Upon recognition of foreign antigens and with the presence of co-stimulatory molecules, B-cells and T-cells express cell surface activation markers, attack foreign antigens, secrete cytokines, stimulate each other, and proliferate. T-cells only recognize foreign proteins presented on MHC, while B-cells can also target foreign DNA, lipids, or carbohydrates. During B and T-cell development, self-antigens are presented to B and T-cells to select out self-reacting types, and to ensure only B and T-cells that recognize and attack foreign antigens are in the circulation. V(D)J recombination in the primary lymphoid organs creates the incredibly diverse and unique repertoire of the hypervariable regions of BCR and TCR, and somatic hypermutations contribute to additional BCR diversity. 2016).Ĭellular immune responses from T-cells and humoral immune responses from B-cells are stimulated by exposures to antigens, including pathogens, allergens, and neoantigens. Depending on our cutting-edged SuPrecision™ platform which mainly based on next-generation sequencing (NGS) technique, our scientists have accumulated extensive experience in identifying the whole four types of T-cell receptor (TCR) chains (α, β, γ, and δ) and the vast majority of B-cell receptor (BCR) V(D)J sequences contained in a single sample.įig.1 Structure, function, and diversification of TCR/BCR receptors (Lossius et al. RNA is synthesized from DNA whenever required.Immune Repertoire Sequencing (Rep-Seq) Service for CancerĬreative Biolabs offers the unparalleled mass sequencing service to analyze the immune repertoires for our customers all over the world. Propagation DNA is a self-replicating molecule. RNA has comparatively lesser stability than DNA. Stability DNA is a highly stable molecule. RNA originates in the nucleolus and later moves to its specifically allocated region of the cytoplasm. It also has a presence in the cell organelles like Mitochondria and Chloroplast. Location DNA is located mainly inside the nucleus. RNA comprises Cytosine and Guanine (C-G) pairs and Adenine and Uracil (A-U). Base-pairs DNA consists of Adenine, Thymine (A-T), and Cytosine and Guanine (C-G) pairs. Adenine, Guanine, Cytosine, and Uracil are the types of bases present in RNA. Bases Adenine, Thymine, Guanine, and Cytosine are the bases present in DNA. There are no hydroxyl groups present like those present in deoxyribose. The sugar molecules present in RNA are called ribose. It contains one less hydroxyl group as compared to RNA’s ribose. Sugar Deoxyribose sugar can be found in DNA. When we talk about a big RNA molecule, there are chances that it might be somewhere around a thousand base pairs long. RNA molecules can be of variable lengths but are much shorter than DNA polymers. A chromosome molecule is a single, long DNA molecule which is about several centimetres long. Length DNA molecules have polymers that are comparatively longer than RNA polymers. It later moves to ribosomal protein manufacturing units. The primary function of RNA is to convert the genetic information stored in DNA to build proteins. Function The primary function of DNA is to replicate and store genetic information. In fact, there are times with the RNA strand also forms the secondary double helix structure. The strands of RNA are shorter than that of DNA but are also made up of nucleotides. Comparison Table Parameter of Comparison DNA RNA Full-Form Deoxyribonucleic Acid Ribonucleic Acid Structure DNA is made up of two strands that are arranged in a double helix.
