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 a following reactions that is used to radioactively label DNA?
Synthesis of new DNA.
What is the matching anticodon for ACC?
The matching anticodon for ACC is UGG. Anticodons are complementary to codons, helping to pair tRNA molecules with the correct amino acid during protein synthesis.
How do base pairing rules explain how a strand of DNA acts as a template during DNA replication?
the 4 nucleotide bases are adenine, guanine, thymidine & cytosine. In a double stranded DNA adenine always pairs with thymidine & guanine always pairs with cytosine. so knowing the base pairs in strand we can determine the base pairs of the other strand. hence DNA strand acts as a template during DNA replication.
What nucleotide base in DNA is replaced by a base in RNA?
In DNA thymine is one of the nitrogen bases, but in RNA uracil replaces thymine still leaving four nitrogen bases
What is radioactive thymidine?
Radioactive thymidine is a form of thymidine that has been labeled with a radioactive isotope, typically tritium (3H) or carbon-14 (C-14). It is commonly used in molecular biology research to track DNA synthesis and cell division by measuring the incorporation of the radioactive thymidine into new DNA strands.
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 has the author J E Cleaver written?
J. E. Cleaver has written: 'Thymidine metabolism and cell kinetics' -- subject(s): Cell populations, Radioactive tracers in cytology, Thymidine metabolism
Why only tritiated thymidine used for estimating cell proliferation and not anything other nucleotide?
It is because thymidine is only incorporated into DNA (recall DNA uses A,C,G, and T whereas RNA uses A,C,G,and U). Thus it is a good indicator of DNA synthesis whereas tritiating any of the other bases might also be incorporated into RNA.
What is thymidine birthdating?
Thymidine birthdating is a method used to determine the age of cells in the body. It involves labeling dividing cells with a chemical called thymidine analog, which gets incorporated into the DNA of newly formed cells. By analyzing the presence and distribution of these labeled cells, researchers can estimate when the cells were generated, providing insights into cellular turnover rates and tissue regeneration.
What is a 9 letter word that deals with DNA?
Thymidine- a nucleoside component of DNA; composed of thymidine and deoxyribose
What base does RNA NOT contain?
Thymidine.
Pyrimidine that pairs with adenine?
Thymidine
What is the chemical formula of thymidine?
C10H14N2O5
What is a following reactions that is used to radioactively label DNA?
Synthesis of new DNA.
How many kinds of building blocks are there for DNA?
The Nucleosies: guanosine, adenosine, thymidine and uridine?
In DNA replication adenine bindes with what?
In DNA replication A (adenosine) binds to T (thymidine).
