Answer:The cell membrane functions as a barrier that makes it possible for the cytoplasm to maintain a different composition from the material surrounding the cell. The unit membrane is freely permeable to water molecules but very impermeable to ions and charged molecules. It is permeable to small molecules in inverse proportion to their size but in direct proportion to their lipid solubility.
Explanation:
Answer: Option C) AGU
Explanation:
AGU and AGC are the two codons that code for the amino acid, Serine. These codons are made of three nucleotides, thus they have a triplet nature.
AGU that code for serine is made of Adenine, Guanine and Uracil joined together, carried on the messenger RNA to be added to the growing polypeptide chain.
Answer:
If you use a microscope to view an unknown cell, should you look for a <em><u>nucleus option D.)</u></em> to tell you if it is a eukaryotic cell
Explanation:
Classification of Adenine is given below.
Explanation:
- Adenine is one of the four bases that make up DNA. It corresponds to the letter A of the sequence that combines A, C, G and T in the DNA. Adenine has the property that, when it is in the double helix, it is always forming a pair with the thymine of the opposite strand.
- Adenine is one of the five nitrogenous bases that are part of nucleic acids (DNA and RNA) and in the genetic code is represented by the letter A. The other four bases are guanine, cytosine, thymine and uracil. Adenine is always paired with thymine in DNA.
- A chemical compound that cells use to make the fundamental elements of DNA and RNA. It is also part of many substances in the body that provide energy to cells. Adenine is a type of purine. DNA structure.
- The adenine formula, which is derived from purine, is C5H5N5. It is a component of the nucleic acid chains that is in the nucleotides, as is the rest of the nitrogenous bases of RNA and RNA (uracil, thymine, cytokine and guanine).
- Cytosine (C) is one of the four bases of DNA, the other three being adenine (A), guanine (G) and thymine (T). Within the DNA molecule, the cytosine bases are located in a chain forming chemical bonds with the guanine bases of the opposite chain
- Adenine and thymine are complementary (A = T), linked by two hydrogen bridges, while guanine and cytosine (G≡C) are linked by three hydrogen bridges. Since RNA does not contain thymine, complementarity is established between adenine and uracil (A = U) by two hydrogen bridges.
