a) How is DNA transcription different than DNA replication/synthesis? b) What is the role of messenger RNA (mRNA) during DNA transcription? c) What happens to the mRNA after transcription is complete (i.e., where does it go)? In what way does DNA methylation typica...
Explain the differences between DNA and RNA. How is RNA formed from DNA? What are the differences between DNA, RNA, and mRNA? What happens to the DNA after transcription? Out of DNA and RNA which is more negatively charged? What is RN...
This new sequence is a strand of mRNA, and this process of making it is calledtranscription. When transcription is complete, the mRNA leaves the nucleus and enters the main body of the cell where it is picked up by ribosomes — cellular “machines” that make proteins from mRNA through a ...
tRNA, or transfer RNA, is the "decoder" of the mRNA message during protein translation. After transcription, tRNA is extensively modified to include nonstandard bases such as pseudouridine, inosine, and methylguanosine. By themselves, ribosomes cannot form a protein when the mRNA makes contact. ...
What happens during the s phase of interphase? Cells Life: A cell has a life that is similar to most of the living organisms on Earth. They are born, they grow, and they reproduce by splitting into two new cells. Cells spend most of their life in a stage known as Interphase. ...
TLR4 is a transmembrane protein that belongs to the pattern recognition receptor family (PRR family), it recognizes molecules like lipopolysaccharide (LPS) thanks to an accessory protein known as MD-2 [30]. TLRs activate transcription factors like NFkB, AP-1 and IRF inducing proinflammatory ...
The presence of a “cytokine-adjuvant” such as GM-CSF raises the possibility that helper T cell differentiation or an entire immune response can bypass the need for the driving cytokines. There is little information about what happens to a majority of T cells that are presented with antigen ...
Once inside the cell there are two types of genomic receptor that can bind Cort and become gene transcription factors. The mineralocorticoid type receptor (MR) binds with high affinity and so can be saturated at low levels of Cort. The glucocorticoid type receptor (GR) has a lower affinity ...
But can we approach the question another way? When significant gene expression changes occur in the genome, such as plastic responses to the environment or events, such as caste development, what happens to DNA methylation? While studies of genome-wide DNA methylation patterns have not indicated ...
If you want to understand how your body works, you need to understand cells. Everything from reproduction to infections to repairing a broken bone happens down at the cellular level. If you want to understand new frontiers like biotechnology and genetic engineering, you need to understand cel...
