What is heavy DNA?
"Heavy DNA" refers to DNA labeled with a heavy isotope, such as nitrogen-15 or carbon-14, for research purposes. By incorporating these heavy isotopes, scientists can track the movement and replication of DNA in experiments.
What is meant by hot and cold radio-isotope labeling with reference to DNA sequencing?
Hot labeling involves incorporating a radioactive isotope into DNA during sequencing, offering high sensitivity but potential hazards. Cold labeling uses non-radioactive isotopes, like fluorescent dyes, for safer detection. Both methods aid in tracking DNA fragments during sequencing.
What is one way that changes can occur in a DNA sequence?
A radioactive carbon isotope can "convert" ... changing the chemistry of a codon.
What radioactive isotope did hershey and chase use to tag phage DNA?
Hershey and Chase used radioactive sulfur-35 to tag phage proteins and radioactive phosphorus-32 to tag phage DNA in their experiments on bacteriophages.
How is a radioactive isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.

What type of isotope was used to follow the construction of new DNA molecules during successive generations?
The isotope used was thymidine labeled with a radioactive isotope such as tritium (3H) or carbon-14 (14C). Thymidine is a nucleoside that gets incorporated into DNA during the replication process, allowing researchers to track the synthesis of new DNA molecules.
What is one way our DNA can change and cause a mutation?
A radioactive carbon isotope can "convert" ... changing the chemistry of a codon.

What is the stable isotope that is formed by the breakdown of a radioactive isotope?
The stable isotope formed by the breakdown of a radioactive isotope is called a daughter isotope. This process is known as radioactive decay, where a radioactive isotope transforms into a stable daughter isotope through the emission of particles or energy.
What radioactive isotope did hershey and chase use to tag phage DNA?
Hershey and Chase used radioactive sulfur-35 to tag phage proteins and radioactive phosphorus-32 to tag phage DNA in their experiments on bacteriophages.
244 94Pu is an of plutonium?
isotope
An element with a number of neutrons different from its normal number is called a what?
It is called an isotope.
What is silicons most common isotope?
The most common isotope of silicon is the isotope 28Si: 92,23 %.
How is a radioactive isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.
How is radioactive Isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.
