Particles or molecules that are too big to fit through regular pores in the cell membrane, or have to big an electric charge, against the current of passive transport ( lower to higher ).
Answer:
Earth is the third planet from the Sun at a distance of about 93 million miles (150 million km).
Answer:
The function of biomolecule inside our body system fully depends on the structure of that biomolecule.It is because the functional groups that participate in a chemical or biochemical reactions are arranged in a specific array in the structure of that biomolecule or macromolecule.
Explanation:
a enzyme structure/catalysis Enzymes are proteinecious in nature.Enzyme contain various amino acids in its active site such as histidine,serine,glutamic acid etc The amino acids of the active site of that enzyme interact with the substrate resulting in the formation of the product.
b mRNA structure/protein synthesis mRNA or messenger RNA consist of nucleotide sequence.The 3 concequetive nucleotides of an mRNA is termed as codons.Each codon codes for specific amino acid.The so formed amino acid linked with the adjacent amino acid by peptide linkage.
c cell membrane structure and signal transduction cell membrane contain various surface protein that act as receptor to detect signals by binding with signaling molecule during signal transduction process.
Answer:
Harshey and chase labeled T2 bacteriophage with radioactive sulfur and radioactive phosphorus. As DNA contains phosphorus, not protein and protein contain sulfur, not phosphorus, therefore, the presence of radioactivity in cell can determine which is the genetic material
.
Then Harshey and Chase infected <em>E.coli</em> with T2 bacteriophage and centrifuged the cell. They found radioactive phosphorus in cell pellet and radioactive sulfur in supernatant.
So by this experiment, they concluded and proved that DNA is the genetic material that gets transfer from one generation to another.
