The cell needs to carry out transcription before it can begin translation because transcription is the first step of gene expression, whereby the segments of DNA is copied into RNA in other words mRNA by enzymes RNA polymerase.
Both RNA and DNA are nucleic acids and they use base pairs of nucleotides as complementary language. It is during transcription when DNA sequence is read by an RNA polymerase which produces antiparallel RNA, complementary strand called primary transcript.
Transcription unit is the stretch of DNA which is transcribed into an RNA molecule and it encodes a protein then the transcription produces messenger RNA or mRNA the mRNA serves as a template for synthesis of proteins through the process of translation.
The transcribed gene may encode for either ribosomal RNA or rRNA, non-coding RNA for example microRNA. RNA performs a fundamental role in functions within a cell whereby it helps to regulate, synthesize, and process proteins.<span>

Answer:
They deliver pollen from the stamens of plants to the ovaries of other plants.
Explanation:
Answer:
The correct answer is option A, that is, may function in preventing autoimmune reactions.
Explanation:
The Tregs or the regulatory T cells refers to the T cells that exhibit a function in suppressing or regulating other cells in the immune system. They monitor the immune response to foreign and self particles and assist in preventing autoimmune disease. The Tregs generated by a normal thymus is known as natural. They are produced due to the proliferation of naive T cells external to the thymus.
