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., wher
a) What happens to the mRNA after translation is complete? b) What is a transfer RNA (tRNA), and what does it do? c) What is produced and then used by the cell at the end of translation? What is carried by tRNA? a) Codons b) Amino acids c) Ribosomes d) Base pairs ...
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. ...
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 ...
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 ...
What is the function of 5 cap? The 5' cap is added to the first nucleotide in the transcript during transcription. The cap is a modified guanine (G) nucleotide, and itprotects the transcript from being broken down. It also helps the ribosome attach to the mRNA and start reading it to ...
