The two energy equivalent molecules that contains phosphates
as part of their structure are ATP which is adenosine triphosphate and GTP which
is guanosine triphosphate. Both of these two have three phosphates and two high
energy bonds. In GTP, they are certain to guanosine while in ATP, the phosphate
groups are certain to adenosine.
it's kinda really complex you have animals like snakes evolution says they used to have legs how can this be proven? This is proven by vestigial structures as some snakes like certain pythons still have legs however, they are underdeveloped and are used for nothing. Whales have pelvis bones this may not seems special but it is because every chordate that has ever walked on land has one thing in common and that's a pelvis this along with other data gathered really concrete the idea of evolution into reality
A) Each DNA nucleotide is made up of a sugar, a phosphate group ... Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are ... In the case of RNA, the five-carbon sugar is ribose. DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix. Base-pairing takes place between a purine and pyrimidine: namely, A pairs with T, and G pairs with C. In other words, adenine and thymine are complementary base pairs, and cytosine and guanine are also complementary base pairs. This is the basis for Chargaff’s rule; because of their complementarity, there is as much adenine as thymine in a DNA molecule and as much guanine as cytosine. Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are connected by three hydrogen bonds. The two strands are anti-parallel in nature; that is, one strand will have the 3′ carbon of the sugar in the “upward” position, whereas the other strand will have the 5′ carbon in the upward position. The diameter of the DNA double helix is uniform throughout because a purine (two rings) always pairs with a pyrimidine (one ring) and their combined lengths are always equal.
