转录(transcription):是蛋白质生物合成的第一步。转录是以DNA中的一条单链为模板,游离碱基为原料,在RNA聚合酶催化下合成mRNA链的过程。翻译(translation):在蛋白质合成期间,将存在于mRNA核苷酸序列按照一定的遗传密码转化为氨基酸序列的过程。转录和翻译都是遗传信息传递过程中非常重要的步骤。
DNA and RNA both consist of nucleotides which contain a sugar, a base and a phosphate group. However there are a few differences. Firstly, DNA is composed of adouble strandforming a helix whereas RNA is only composed ofone strand. Also the sugar in DNA isdeoxyribosewhereas in RNA it isri...
The processes of transcription, RNA processing (in eukaryotes), and translation constitute the pathway that leads to the conversion of genetic information in the linear sequence of bases in genomic DNA into the linear amino acid sequences of functional proteins. Thus, DNA undergoes transcription to ...
Transcription by RNA polymerase (RNAP) is coupled with translation in bacteria. Here, we observe the dynamics of transcription and subcellular localization of a specific gene locus (encoding a non-membrane protein) in living E. coli cells at subdiffracti

1、Transcription and Translation,From DNA to RNA to protein,Overview,Genes in DNA contain information to make proteins. The cell makes mRNA copies of genes that are needed. The mRNA is read at the ribosomes in the rough ER. Protein is produced.,Key Players,mRNA carries the information from...
Here, we characterize a previously unidentified PTENpg1 encoded antisense RNA (asRNA), which regulates PTEN transcription and PTEN mRNA stability. We find two PTENpg1 asRNA isoforms, alpha and beta. The alpha isoform functions in trans, localizes to the PTEN promoter, and epigenetically modulates...
Basic Principles of Transcription and Translation RNA is the intermediate between genes and the proteins for which they code Transcription is the synthesis of RNA under the direction of DNA Transcription produces messenger RNA (mRNA) Translation is the synthesis of a polypeptide, which occurs under th...
