유전자 발현

 유전자 발현이란 무엇인가?
Gene expression is the process in which DNA directs the synthesis of functional products, such as proteins. Cells can regulate gene expression…
 중심 원리
The central dogma of biology states that information encoded in the DNA is transferred to messenger RNA (mRNA), which then directs the synthesis of…
 전사 인자
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component…
 RNA 구조
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form…
 RNA 안정성
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural…
 pre-mRNA 처리
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor…
 RNA의 종류
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform…
 마이크로 RNA
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of…
 RNA 스플라이싱
The process in which eukaryotic RNA is edited prior to protein translation is called splicing. It removes regions that do not code for proteins and…
 후성유전적 조절
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases…
 RNA 간섭
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the expression of a gene by binding to its messenger RNA (mRNA)…
 오페론
Prokaryotes can control gene expression through operons—DNA sequences consisting of regulatory elements and clustered, functionally related…
<em>C. 선 충</em> 에서 광범위 한 범위 식이 제한 유전자 식 수준 동안 수명 변조에서 인코딩된 정보의 정량화
Sensory systems allow animals to detect, process, and respond to their environment. Food abundance is an environmental cue that has profound effects…
내부 기준에 FACS 및 qPCR에 사용 단일 세포 유전자 발현 프로파일 링
Gene expression measurements from bulk populations of cells can obscure the considerable transcriptomic variation of individual cells within those…
