Asked in Genetics, Sun Tanning
After a long week of sunbathing on the beach what type of DNA damage might you be concerned about?
Thymine Dimers are what you should be concerned about... Thymine dimers cause kinks in DNA T-A T A ~ | T-A T A The paring of T to T causes the kink and the A-T connection is broken... ...

What bonds to thymine in DNA?
The Watson-Crick base pair of Thymine is Adenine. The two molecules are bound together by a set of three hydrogen bonds. Thymine can also form what are known as Thymine dimers when exposed to UV radiation, which is the source of damage to DNA from overexposure to UV radiation and can cause cancer. ...
How does going to a tanning salon relate to the structure and function of DNA?
One thing is the UV rays encountered in a tanning salon which can cause breakage in DNA linkage and, possibly, lead to skin cancer. Thymine dimers can result from this breakage and then the thymine crossing normal linkage and binding to another thymine. ...

Which form of radiation can break a bond in some molecules?
Ultra violet radiation does this all the time to DNA molecules. Thymine dimers are the result of this radiation on epidermis cells. ...

What will happen to a eukaryotic cell lacking telomerase?
It would be unable to reapir thymine dimers.
What effects does ultraviolet radiation have on Serratia marcescens?
UV radiation exposure to S. marcescens colonies results in DNA mutations. The radiation energy is absorbed by the bacteria and if exposure is long enough, thymine nitrogenous bases adjacent to each other in DNA strands will form cyclobutane rings called thymine dimers. When replicating DNA and multiplying, the enzymes responsible for replication will bond a different base in place of the thymine bases and a mutation will result. How if affects the DNA, and consequently protein synthesis, is entirely dependent on the location...
What are the nucleotides called that pair with thymine in DNA?
Adenine always pairs with thymine in DNA.
Asked in Genetics
Which molecules is typically found in DNA but not RNA?
Thymine is found in DNA but not in RNA. Uracil replaces thymine in RNA. In other words: DNA has thymine. RNA has uracil. ...
Does DNA have the nitrogen base thymine or uracil?
DNA has thymine and RNA has Uracil nitrogen base.

Why does UV light kill germs?
Germicidal ultraviolet (UVC) light kills cells by damaging their DNA. The light initiates a reaction between two molecules of thymine, one of the bases that make up DNA. UV light at this wavelength (shortwave UV or UVC) causes adjacent thymine molecules on DNA to dimerize. The resulting thymine dimer is very stable. If enough of these defects accumulate on a microorganism's DNA its replication is inhibited, thereby rendering it harmless. The longer the exposure to UVC light, the more thymine dimers are formed...

What are pieces that are removed from an RNA molecule but have complimentary sequences in DNA?
thymine and uracil thymine is in DNA, and uracil is in RNA
