Answer:
1.a sequence of sugars, phosphates, and nitrogenous organic bases: Nucleic acid
2.a complex molecule containing the genetic code: DNA
3.a nucleic acid that participates in the synthesis of proteins: RNA
Explanation:
Nucleic acids are the biomolecules that are composed of a sequence of nucleotides. Each nucleotide has a pentose sugar, a nitrogenous base, and a phosphate group. There are two types of nucleic acid called DNA and RNA. DNA differs from RNA with respect to the pentose sugar and the presence of a thymine base. The sequence of the template DNA strand serves as a genetic code.
It is copied into the nucleotide sequence of mRNA during the process of transcription. The molecules of mRNA serve as a template for the synthesis of proteins when their nucleotide sequence is read in the form of genetic triplets.
All cells have a cell membrane. its basically what protects the cells from getting toxins that are sometimes entering your body. without a membrane on all cells, you would get sick a lot!!
<span>Polypeptide

When Polypeptides join together, they form protein. The term Polypeptide chain is used to define the combination of Polypeptides. They are joined together by the peptide bonds. These Polypeptides are chains of amino acids. When one or more Polypeptide chains joined together, that is the time when Protein was born. As we all know, protein is very essential to our body. Because protein helps our body to function well. Protein makes our cells function properly. Can you imagine our body without protein? Thanks to Polypeptides chains that are joined together to form Protein so our body can function well. </span>
