Hershey and Chase Experiment
Why are radioactive isotopes a valuable tool in molecular biology? Molecular biology mostly takes place on a scale too small to be directly observed by researchers. While cells, organelles, and even macromolecules can be visualized with high-powered microscopes, the molecular processes that drive biology cannot be seen and need to be inferred from experiments. Radioactive isotopes are versions of elements such as carbon, nitrogen, or phosphorus that unstable and release neutrons to become more stable isotopes. The radioactive signal given off by the emission of neutrons allows scientists to detect the isotopes even when they cannot be seen. Adding isotopes to biological systems allows scientists to trace both molecular pathways and the locations at which these pathways occur.
<span>Refraction happens when there</span> is a bending of path of a light wave as it
passes across the boundary separating two media and the degree of bending is
determined in part by the total change in velocity as the light<span> passes from one medium to the other. In
addition, the change in speed experienced by a
wave when it changes medium can result in a number of beautiful optical effects. </span>
The mRNA sequence GGU AGC CGG encodes the amino acid sequence Gly-Ser-Arg (Option A).
<h3>What is the genetic code?</h3>
The genetic code makes reference to the linear order of DNA/RNA nucleotides in codons that specify different amino acids.
The genetic code starts in DNA to be transcribed to mRNA and finally translated into protein sequences.
In conclusion, the mRNA sequence GGU AGC CGG encodes the amino acid sequence Gly-Ser-Arg (Option A).
