An analysis of a cell indicated a high lipid content in the membranes, a high protein content in the vesicles being mobilized an
Anon25 [30]

The option that best illustrates the similarity and difference in the elemental makeup of these molecules is that carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements. That is option B.

Carbohydrates are macromolecule found is food substances that plays a vital role of energy supply to the body.

It is made up of chemical elements such as carbon,hydrogen and oxygen in the ratio of 1:2:1.

Lipid is another macromolecule found in food which is an energy reserve for the body.

Lipids are made up of elements seen in carbohydrates such as carbon, hydrogen and oxygen but contain many more hydrogen atoms than oxygen atoms.

Proteins are another type of macromolecule found in food which helps in body building and repair of worn out tissues.

Proteins are made up of elements seen in carbohydrates and lipids with the addition of nitrogen atom.

Therefore, carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements.

Explain what frame shift means and is it more or less likely to cause a noticeable mutation than a substitution
harina [27]

Answer:

A frameshift mutation can be described as a genetic mutation in which a single nucleotide or more than one nucleotide is inserted or deleted from the sequence of the DNA. As the gene expresses itself in the form of triplets of a genetic code, insertion or deletion can cause devastating changes in the genetic code due to which wrong proteins will be synthesized.

Frameshift mutations can be more noticeable than the substitution mutation. In a substitution mutation, only one of the nucleotides is shifted with another. The entire genetic code is not affected by it.

The only time the yellow can be expressed entirely Is when the combination is rr.
