Your heart then pumps it through your body to provide oxygen to the cells of your tissues and organs. As the cells use the oxygen, carbon dioxide is produced and absorbed into the blood. Your blood then carries the carbon dioxide back to your lungs, where it is removed from the body when you exhale.
DNA polymerase has 5'-3' activity. All known DNA replication systems require a free 3' hydroxyl group before synthesis can be initiated (note: the DNA template is read in 3' to 5' direction whereas a new strand is synthesized in the 5' to 3' directionâthis is often confused).
HI! The discovery of the structure of DNA was a landmark in molecular biology research. Which of the following is a correct representation of DNA? (No, This is a left handed double helix.) (That is correct) (No, This is not the DNA double helix.) (No, The DNA helix does not have evenly spaced coils.) DNA is a right-handed double helix. If you curl the fingers of your right hand in the direction of the helical twists, your thumb will point upwards. This section of DNA has a sequence of nucleotides like this: CCGTATACAT Reading left to right, what is the nucleotide sequence on the other strand of DNA in this section?
