First one is C) A phosphate group is added, and the second is D) Kreb's cycle
The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as the nucleus, ribosomes, and mitochondria which are crucial for protein synthesis, assembly, and repair. In other words, they lack both the information and the machinery for making or repair of proteins.
Due to lack of DNA and cell organelles, red blood cells cannot be able to satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.
DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm, then translating or decoding this information, which results in the making of protein.
Answer:
All given options are correct.
Explanation:
Biomolecules may be defined as the organic molecules that are present in the living organism. Four important biomolecules are proteins, carbohydrates, fats and nucleic acids.
The biomolecules are known as macromolecules because they are made of large units of molecule. The mRNA that translates to form a enzymes is macromolecule because RNA is made of large units of nucleotides. Lipid that found in cell membrane are macromolecules because they are made of more than 1000 atoms. Protein that are involved in DNA replication are macromolecules as they have large units of amino acids.
Thus, all the given option are correct.
E . all of the statements are true hope i’m correct
The words that comes in the blanks are the cytoplasm; nucleus.
<span>Newly synthesized proteins encoded in genes in the nucleus are found in the Cytoplasm and dna are observed in the nucleus in eukaryotes.
</span>Any organisms form which have cells or complex cells have a cell nucleus different organelles are encased inside layers or membrane is Eukaryotes and they are related to the taxon Eukarya or Eukaryota.
