Answer: The correct answer is A) Prokaryotes have no nucleus.

Prokaryotes are the single celled organisms, which do not possess a well defined membrane bound nucleus and other organelles. The genetic material is all these organisms is present in the cytoplasm of the cell.

Example- Bacteria.

Whereas, eukaryotes are single or multicellular organisms, which possess a well defined nucleus ( with genetic material in it) as well as other organelles like mitochondria, golgi complex, endoplasmic reticulum.

Example- Plant cell.

Thus, option A) is the right answer.

A frameshift mutation that occurs very early in a protein sequence would have what effect on the protein's structure? A. The pri
AlekseyPX

Answer:

C. Primary, secondary, and tertiary structures would be altered

Explanation:

Frameshift mutations refer to the mutations that change the reading frame of the gene. Frameshift mutations are mostly caused by insertion or deletion of nucleotide since addition or loss of nucleotide alters all the codons present downstream of the point of the mutation site. If frameshift mutation occurs at the beginning of the protein sequence, all the downstream amino acids would be altered.

The changed amino acid sequence would alter the primary structure of the protein. Since the secondary and tertiary structure of proteins is determined by interactions between the R groups of amino acids, their polarity, charge, etc., the altered amino acid sequence would also alter secondary, and tertiary of the protein.

In proteins, secondary, tertiary, and quaternary levels of structure depend on the primary structure.
Fittoniya [83]

Answer:b. Amino acid sequence, hydrogen bonding between backbone groups, the overall shape of a single polypeptide, and combinations of tertiary structures.

Explanation: Primary structure is the amino acid sequence in the polypeptide chain. When the sequence is altered due to mutation it can lead to formation of entirely new amino acid sequence.

Secondary structure could be the helical structure or the Beta pleated sheet. It is form from the interaction of atom that are backbones.It is the hydrogen bond between amino Hydrogen and carboxyl oxygen atom in the backbones

Tertiary structure- Overall structure of polypeptide. It result from interaction of the R groups amino acids. It gives the shape of the polypeptide.

Quantenary- Are protein made up of multiple polypeptide chain. This chain are also called subunit. It is the combination of all tertiary structures given rise to a functional protein.

Multiple choice just double checking the answer would be D Correct?
Paladinen [302]

Explanation:

John Dalton proposed the theory of matter which is popularly known as the Dalton's atomic theory. In the atomic theory, Dalton identified from his experiments on gases that every matter is made up of small indivisible particles called atoms. These atoms are the smallest fractions of a matter.

  • All the atoms of an element are all alike.
  • Compounds form from atoms by simple whole number combinations alone.
  • Chemical combination of atoms involves the rearrangement of reactants.

Therefore, using these clues you should be able to answer the question.
