A cell is the smallest life unit
Answer:
mRNA: AAGCGAAAGA
Explanation:
amino acid: lysine , arginine
I think the answer would be A.
Answer:
It will swell and eventually burst because water from the environment is flowing into the cell
Explanation:
This question is describing OSMOSIS, which is the movement of water from a region of high concentration to a region of low concentration across a semi-permeable membrane. The osmotic process is facilitated by the formation of an OSMOTIC GRADIENT i.e. difference in concentration between the two sides of the membrane.
In this case, an animal cell containing an internal salt concentration of 70% (hypertonic) were placed in a salt solution with a concentration of 20% (hypotonic), OSMOSIS will occur in the sense that water will move from where it is more concentrated (salt solution) into where it is less concentrated (animal cell), hence, the animal cell will SWELL AND EVENTUALLY BURST.
Answer:
The two problems that the transfer of information from DNA to protein must overcome are:
- How to bring the information from the nuclear DNA to the place of protein synthesis?
- How to convert this DNA information into amino acids and then into proteins?
Explanation:
The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.
<h3>How to bring the information from the nuclear DNA to the place of protein synthesis?
</h3>
The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.
<h3>How to convert this DNA information into amino acids and then into proteins?</h3>
Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.
