Answer:
c. Thymine dimer
Explanation:
Thymine dimer
Thymine dimer ( also called the DNA damage ) that is repaired by the nucleotide excision repair which involves the breakage of the phosphodiester bond on the side of the damage , and results in the excision of an oligolnueotide of 10-12 nucleotides in length .
But the base excision repair involves the removal of the damaged base , removal of short polynuceotide and resynthesis of this area with DNA polymerase .
We are describing their physical features.
Answer:
An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the North American Plate. The Pacific Plate consists of most of the Pacific Ocean floor and the California Coast line. The North American Plate comprises most the North American Continent and parts of the Atlantic Ocean floor. The primary boundary between these two plates is the San Andreas Fault. The San Andreas Fault is more than 650 miles long and extends to depths of at least 10 miles. Many other smaller faults like the Hayward Northern California and the San Jacinto Southern California branch from and join the San Andreas Fault Zone.

Answer:
Answer is 4. Affected persons carry the Philadelphia chromosome.
Explanation:
The Philadelphia chromosome got its name from the city where it was discovered in 1960 by Nowell and Hungerford.
The Philadelphia chromosome is known to be an abnormal chromosome, which is found sometimes in the leukocyte. It is known to be responsible for causing chronic myeloid leukemia,CML.
The chronic myeloid disorder is the cancerof the white blood cell, i.e the leukocytes.
It occurs in this leukemia. CML occurs occasionally in children and adolescents. represents approximately 15% of all cases of leukemia in the US. The average age of onset is between 40-50 years.
Answer:
The Light Reactions of Photosynthesis[edit] The light reactions occur primarily in the thylakoid membrane of the chloroplast. ... The high concentration of hydrogen ions pumped into the inner thylakoid space (the thylakoid lumen) can then be used to make ATP by a process called chemiosmosis.
