The process by which genetic information flows from DNA to RNA to protein.
The anticodon matches with a codon on the mRNA.
The study of heritable changes that alter gene expression without changing the primary DNA sequence.
Survival of motor neuron (SMN) protein.
tRNA carries an amino acid corresponding to its anticodon.
An autosomal recessive disease characterized by progressive muscle weakening due to the loss of motor neurons.
Single-stranded RNA with a length of 18-25 nucleotides that regulates gene expression at a post-translational level.
It blocks a helper protein involved in splicing.
By binding to mRNA to either destroy and recycle its components or preserve them for later translation.
The process of converting RNA back to DNA, primarily seen in viruses like HIV.
The small and large subunits assemble around the mRNA.
A C to T mutation.
It cannot function properly and is broken down.
SMN1 and SMN2.
It lacks exon 7 due to a mutation in SMN2, leading to a shorter, non-functional SMN protein.
SMN1 is fully functional, while SMN2 is only partially functional.
mRNA leaves the nucleus and travels to the ribosomes in the cytoplasm.
Francis Crick.
A-site, P-site, and E-site.
Chromosome 5.
The completed polypeptide chain detaches from the ribosome and folds into conformation.
RNA is translated into protein.
Chemical modifications added by specific enzymes to regulate gene expression.
They synthesize new methylation marks for DNA methylation.
B-DNA.
Major is the larger gap; minor is the smaller gap.
Right-handed helix.
Free RNA nucleotides are added to the template strand in the 5' to 3' direction.
TFII components and RNA polymerase II bind to the promoter region.
%T = %A and %C = %G.
<p>Ribose and phosphate.</p>
Adenine, thymine, guanine, cytosine.
Because there are only 2 hydrogen bonds between them.
It removes introns using small nuclear ribonucleoproteins (snRNPs) and RNA.
It is capped at the 5’ end and receives a poly-A tail at the 3’ end.
When a 'stop' sequence is reached or occurs randomly after the transcribed gene.
It binds to the DNA at the TATA box sequence.
