Explanation:
Free amino acid do not have a peptide bond , as the amino acid act as a monomer which multiplies and linked via peptide bond to generate protein chain .
A free amino acid have a carbonly group (- COOH ) and a -NH₂ group .
The formation of protein chain require at least two amino acids linked via peptide chain .
The role of peptide chain only comes in case of protein , because it acts as a linking species .
Hence , free amino acid does not have any peptide chain .
You are looking at tissue under a microscope. One cell shows half the amount of DNA of some of the other cells. This cell is most likely to be in the G1 phase where the cell has just divided.
Hope this answers the question. Have a nice day.
D is the correct answer: fungi cannot cure diseases
Answer:
The main reason is growth factor ligands do not bind as efficiently to receptors.
Initially, normal cells work efficiently on binding of enzymes, growth factors or ligands and cellular growth cycle runs effectively but with the passage of time, cellular aging or organismal aging can lead to decrease efficiency of cellular recepotors binding with the growth factor ligands gradually.
Honestly, dog-walking and dog-sitting is a really great job and <span>it is also really fun and rewarding</span>. The average wage for a Dog Walker is $13.27 per hour. Therefore, being a freelancer, I would love to spend my spare time on the dog walk.
