Concept explainers
(a)
Interpretation:
80% divergence of two proteins from a common ancestor.
Concept introduction:
All the living organisms arise from primitive organisms. The new organisms are called descendents while the primitive organisms are called forefathers or ancestors.
(b)
Interpretation:
50% divergence of two proteins from a common ancestor.
Concept introduction:
The evolutionary process in which organisms from a common ancestor attainnew traits and become different from each other. The amino acid sequence gives an interpretation about the rate of divergence in different organisms.
(c)
Interpretation:
20% divergence of two proteins from a common ancestor.
Concept introduction:
The proteins are formed from the amino acids. The sequence of amino acids is used for evolutionary studies. It helps in detecting the ancestors of different organisms.
(d)
Interpretation:
10% divergence of two proteins from a common ancestor.
Concept introduction:
The descended organisms inherit many traits from their ancestors that help them in their survival. Divergence is a part of the evolutionary history of an organism. The descendants adapt to the new environment by the process of divergence.

Draw the structure that would result if the newly formed phosphodiester bond were hydrolyzed.arrow_forwardDNA Structure A. Draw an A-T base pair with the appropriate number of hydrogen bonds. You don’t have to include all the details such as every side-group but do depict the 3’ OH groups. B. What is meant by anti-parallel when referring to a DNA molecule? C. What are the major and minor grooves in the DNA structure and what significance do they have?arrow_forwardWhich statements are true? Explain why or why not.1 Each strand in a β sheet is a helix with two aminoacids per turn.2 Intrinsically disordered regions of proteins can beidentified using bioinformatic methods to search genes forencoded amino acid sequences that possess high hydro-phobicity and low net charge.3 Loops of polypeptide that protrude from the sur-face of a protein often form the binding sites for other mol-ecules.4 An enzyme reaches a maximum rate at high sub-strate concentration because it has a fixed number ofactive sites where substrate binds.5 Higher concentrations of enzyme give rise to ahigher turnover number.6 Enzymes that undergo cooperative allosteric tran-sitions invariably consist of symmetric assemblies of mul-tiple subunits.7 Continual addition and removal of phosphatesby protein kinases and protein phosphatases is wastefulof energy—since their combined action consumes ATP—but it is a necessary consequence of effective regulation byphosphorylation.arrow_forward
- Read it carefully.. Draw only correct diagrams.. In the Watson-Crick DNA base pairing model, Adenine (A) binds to thymine (T), guanine (G) binds to cytosine (C). 1. Draw the structures of thymine and adenine stabilized by Watson-Crick base pair interaction. 2. Also draw the structure of the amide group of glutamine in an interaction of this T-A pair in a way that maximally satisfies the hydrogen bonding capacity of amide.arrow_forwardMolecular Biology Cytochrome c is a protein found in mitochondria. It is used in the study of evolutionary relationships because most animals have this protein. Cytochrome c is made of 104 amino acids joined together. Below is a list of the amino acids in part of a cytochrome protein molecule for 9 different animals. Any sequences exactly the same for all animals have been skipped. For each non-human animal, take a highlighter and mark any amino acids that are different than the human sequence.

I want to extract the blood from horseshoe crab to the spinach leaves. I found one article that said spinach leaves can grow human tissue. So, I assume that I put the horseshoe crab blood to the spinach leaves can grow animal protein (coagulogen). Then, we use the coagulogen to produce medicine. Provide me detail steps on how to create this GMO.arrow_forward
