a The prokaryotic ribosome, which has an overall rating of 70S, is actually composed of two smaller subunits. They fit together to form a miniature “factory” where protein synthesis occurs. . 初核质核糖体,有70S总评,由二个更小的亚单位实际上组成。 他们一起适合形成一家微型“工厂”蛋白质综合...
-Splicing: This is the process of removing non-coding regions (introns) from pre-mRNA and joining the coding regions (exons) together. This process occurs in the nucleus after transcription. 3.Role of RNA in Each Process: -Metabolism: While metabolism involves many biochemical pathways, some of...
In which cell organelle of the yeast cell do many of the reactions of cellular respiration take place? a. vacuole b. ribosome c. nucleus d. mitochondrion What cellular process occurs in Chloroplasts? What is use of DNA in mitochondria and chloroplast?
Glycolysis is the breakdown of 6 carbon glucose converted into two molecules of three carbon pyruvate, which occurs in ten steps. The first steps are known as the preparatory phase, and the remaining five steps are known as the payoff phase. ...
Once the process of transcription is completed, the mRNA molecule is transported to the ribosome. Here, the ribosome will use the mRNA molecule to synthesize a protein. Answer and Explanation:
Ribosomesare the sites where proteins are synthesised. The transcription process where the code of the DNA is copied occurs in nucleus but the main process of translating that code to form other protein occurs in ribosomes. What are the 3 steps of transcription?
Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes toa ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein. ...
A related issue is whether cellular RNAs are available for interaction with the viral coat proteins, since most are likely to be in complexes of their own, such as ribosomes. In this scenario, the selection of the viral RNA for packaging depends on the coupling of assembly to replication, ...
The initiator methionyl-tRNA (Met-tRNAi) is brought to the ribosome by initiation factor eIF2 in a complex also containing GTP, which is subsequently hydrolysed during the initiation process. After each initiation event, the active GTP-bound form of eIF2 must be regenerated from [eIF2.GDP] ...
It is clear that RFH occurs in distantly related bacteria. It is possible that horizontal gene transfer contributed to the expansion of RFH across lineages, since most of the bacteria where we found RFH genes are either animal or plant pathogens and therefore can share a com- mon habitat in ...
