Explanation:
Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.
Answer:
The correct answer would be d. thymus.
The thymus is a specialized lymphoid organ of an immune system.
It serves as the site for training and maturation of T-lymphocytes or T cells.
It is composed two identical lobes each containing outer region termed as cortex and inner region termed as medulla.
T-cells are first trained and selected in the cortex region via positive selection. In this, T cells which are able to bind to foreign antigens are selected and rest are degraded.
The selected T cells then move in the medulla region where they are selected by negative selection. In this, the T cells which binds to self-antigens are degraded and rest survive to become functional T cells.
It's a ! cnidocytes help in defence and also in capturing prey ! so answer is A !!
Answer: The pathway involves the transcription and translation processes.
Explanation:
The DNA present in the somatic cells of the eukaryotic organisms undergoes transcription in which the DNA is used as a template to form mRNA. It occurs in nucleus
The mRNA encodes for a amino acid chain for a specific protein in the process of translation. It occurs in cytoplasm and require a cell organelle called ribosome.
The amino acid sequence for different proteins are different.
