The hydrolysis of atp on the na+/ k+ pump results in
Shalnov [3]
I believe it results to a conformation change that moves the Na+ binding site to the inside of the cell. ATP hydrolysis involves the release of chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate.For example in muscles. The process of moving sodium and potassium ions across the cell membrane is an active transport process involving the hydrolysis of ATP to provide the necessary energy. It involves an enzyme referred to as Na+/K+ ATPase.

1) What two problems does the transfer of information from DNA to protein need to overcome?
swat32

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 /><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 /><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.

Is Ss recessive trait?
Sedbober [7]
When a trait is recessive, an individual must have two copies of a recessive allele to express the trait. Recessive alleles are denoted by a lowercase letter (a versus A). Only individuals with an a genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait.
