Conventional genetic analyses of rRNA  sequence is not possible for prions because they don't contain nucleic acid.Prions do not contain genetic material such as - DNA and RNA.

The unique traits and genetic material information are encoded with the conformation structure and modification of protein.Prions which are responsible for transmissible sponginess encephalitis  is mammals which all known prion disease affect the neural tissues.

There are 253 amino acids exist in multiple conformations and isoform which is found in healthy organisms, most extensively studied proteins. Prions are not destroy easily and remains intact in the presence of radiation , disinfectant and extreme heat.

Describe the relationship between organic compounds, nucleotides, RNA, and a universal genetic code.
makkiz [27]

Answer:

Organic compounds→ nucleotides→ RNA→ universal code.

Organic compounds are the compounds made by living organisms with at least one molecule of carbon linked to different elements like hydrogen, oxygen, or nitrogen.for example: nucleotides.

A nucleotide is the monomer units of nucleic acids- DNA and RNA. Each nucleotide is made up of organic compounds- sugar, a phosphate molecule and nitrogenous bases (adenine, guanine, cytosine, thymine and uracil).  

The arrangement of nitrogenous bases in DNA decides the fate of proteins as the sequence of these bases acts as code arranged in the triplet called "codons" which code for specific amino acids.

Thus, Organic compounds→ nucleotides→ RNA→ universal code is the correct answer.

If a negatively charged ion is more concentrated outside the cell, the forces required to balance the chemical gradient would be
svetlana [45]

Answer:

If a negatively charged ion is more concentrated outside the cell, the forces required to balance the chemical gradient would be directed <u>outwards</u>. Thus, the equilibrium potential for this ion would be <u>negatively</u> charged.

Explanation:

The resting membrane potential is normally due to small excess of negative ions inside of positive ions outside the cells.

The negative charges are attracted to the positive charges and they form a thin layer of negative inside and positive outside of the cell. The rest of extracellular and intracellular fluid remains normal.

If negatively charged ion is more concentrated outside the cell, then the forces will move outwards, in order to balance the gradient. Thus resulting in negative equilibrium potential (The potential at which no movement of the ion occur across the membrane)
