What is tRNA? (transfer RNA) Question:What is tRNA? (transfer RNA) Rough Endoplasmic Reticulum:The rough endoplasmic reticulum (RER) is a ribosome granulated organelle of the cell essential for the production of essential proteins to support biological processes inside the cell. The ribosomes bind...
What is transfer RNA (tRNA)? RNA: Ribose nucleic acids (RNA) are single-stranded molecules, which are polymers of nucleotides. They contain the pentose sugar ribose, a phosphate group and bases guanine, cytosine, adenine and uracil. Answer and Explanation:1 ...
life as we know it could not exist. There are three types of RNA, each with a unique function. mRNA is used to produce proteins from genes. rRNA, along with protein, forms the ribosome, which translates mRNA. tRNA is the link between the two other types of RNA. ...

文章通篇都在介绍在东京如何找到道路的方法。可见只有答案C才最符合本文的主旨。
IDO1, a monomeric heme-containing enzyme, is one of the three enzymes that catalyze the first and rate-limiting step in the kynurenine pathway (KP), leading to the degradation of the essential amino acid tryptophan (TRP) and generation of kynurenine (KYN) and other downstream metabolites, in...
TRP depletion promotes the accumulation of uncharged tRNA, resulting in a GCN2-dependent inhibition of protein synthesis that is accompanied by cell cycle arrest and irresponsiveness to immunological challenges[54]. TRP depletion leads to inhibition of the immunoregulatory kinases mTOR and protein ...
G1 phase: The gap between the completion of mitosis and DNA replication. During this period, various complex macromolecules including mRNA, tRNA, rRNA and proteins are synthesized. S phase: DNA replication period, during which the DNA content doubles. G2 phase: The period from the completion of...
Why is RNA a single strand? What is tRNA structure? What is a single-stranded RNA virus? What is a negative-stranded RNA virus? What is an anticodon of the transfer RNA for valine? What are the pairings for the bases in RNA and DNA?
