Answer:
Nitrogenous bases have two distinct families known as purines and pyrimidine, nitrogenous are the building blocks or monomer units of the nucleic acids.
The major and significant difference between purines and pyrimidines is the difference in their structures-
The purines are divided into two different bases called adenine and guanine and each of them have a two-ringed structure formed with a 9-membered molecule and 4 nitrogen atoms which makes it a large in size than purines.
The pyrimidines are divided into 3 bases that are cytosine, uracil, and thymine and all these have only one single ring of six members and 2 nitrogen atoms. These are smaller in size.
Answer: RNA only.
Explanation:
Translation is a process of decoding of the molecules of messenger RNA and using it for the synthesis of the polypeptide, or a chain of an amino acids. The polypeptide chains coalesce to from the protein. The proteins are building blocks of lives. They are necessary for performing specialized functions in the body of the living being.
Answer:
The cells inside our bodies are “specialized.” This means that each type of cell performs a unique and special function. For this reason, each of the 200 different types of cells in the body has a different structure, size, shape, and function, and contains different organelles.
We are multicellular organisms, different types of cells are required to do different function.
Explanation:
Actually cells in our body won't reproduce, LOL.
It get divided ( see the attached image )
