DNA consists of two types of nitrogenous bases: Purine and Pyrimidine. Purine is a double ringed structure that includes Adenine (A) and Guanine (G) while pyrimidine is a single ringed structure that includes Thymine (T), Cytosine (C) and Uracil (U). In a DNA helix pairing takes place between one purine and one pyrimidine. A pairs with T and U (in case of RNA) and G pairs with C. During a mutation, it is more likely for A to get mutated to G than to T because A and G are similar in structure than T and C and the structure of DNA is not changed.
Answer:
I'll take a look at your question
Explanation:
The Carbon Cycle is important to the life and development of Trees and Plants as a whole.
We breathe in Oxygen that is provided from the Trees that provide that provide it.
We exhale Co2 ((Carbon Dioxide)) for the Trees to breathe in. This entire cycle and process ensures that we survive as a planet.
As it is an essential part of life

microscopic and unicellular, with a relatively simple cell structure Bacteria are the most abundant of all organisms.
To retain a better sense of balance or aid in reaching limbs if a tree living animal. Also, too protect from predator attacks from behind.
<span>The true statement regarding DNA is A) contains deoxyribose sugar. DNA (deoxyribonucleic acid) consists of two strands of nucleotides joined by hydrogen bonds. Each nucleotide contains nucleobase (adenine, thymine, cytosine, and guanine), a sugar deoxyribose, and a phosphate group. The fact that it contains the deoxyribose sugar was the reason the molecule is called deoxyribonucleic acid or DNA.</span>
