B, a nucleus. Nuclei are membrane-bound organelles inside eukaryotic organisms. Eukaryotes are protists, fungi, plants, and animal cells. A bacteria is not a eukaryote, it is a prokaryote, so it does not have the membrane-bound structure of the nucleus.
Be careful, though, bacteria still have DNA. It is simply located in the center of the cell and is not encased in a membrane.
Answer:
never give up its an order if you do then so dose life
Explanation:
never give up
The cell membrane allows this to be true
B) the less porous, the less permeable
Porous means "full of holes."
Permeable means "stuff can go through it."
The more porous something is, the more permeable it is.
<u>Primary structure of the protein </u>can be determined With the knowledge of the nucleotide sequence of a gene.
- Strings of amino acids make up proteins, and strings of nucleotides make up nucleic acids.
- A water molecule is removed during a biological process that links the carboxyl group of one amino acid to the amino group of a nearby amino acid to generate peptide bonds.
- The main structure of a protein is thought to be its linear amino acid sequence.
- A codon is a cluster of three mRNA nucleotides that codes for a particular amino acid.
- Each mRNA produces a protein that has a specific amino acid sequence corresponding to it. The start and stop of translation are indicated by two codons known as start and stop codons.
