Answer: number 8:
they form right angles just do a google search
number 9:
Crayfish turn blood into neurons. ... Olfactory nerves are continuously exposed to damage and so naturally regenerate
number 10: molting is the process of shedding and replacing the rigid exoskeleton and spiders are an animal that molts
Explanation:
Answer:
The correct option is d) UAG
Explanation:
Central dogma can be described as the process in which the transcription and translation occurs. The process by which mRNA is made from the DNA is called transcription and the process by which proteins are made by mRNA is called translation.
The first codon present on the DNA is TAG. The mRNA formed from this codon will be AUC. When this mRNA will travel from the nucleus to the cytoplam, the tRNA will bring the anticodons UAG for the first mRNA codon. Hence, the correct option is D.
You can find the answer in the living environment regent by searching it on google, also if you want I have the answer!
Answer:
Chimpanzees
Explanation:
Chimpanzees are much more closely related to humans in an evolutionary sense that cows are. Chimpanzees and humans are both primates, characterized by features like advanced cognition, grasping hands and feet, and front facing eyes. In contrast, cows belong to a different of bovine animals.
Because we are evolutionary more related to chimpanzees, that means our DNA has undergone less change over evolutionary time. That means that the sequence will be more similar to chimps
Answer:
Part A - Increases the mechanical strength of protein
Part B - Disulfide bonds in the BPTI cysteines residues prevent protein from changing its structure and form
Explanation:
Remaining part of question
Part B
Most globular proteins are denatured and lose their activity when briefly heated to 65 degree C. However, globular proteins that contain multiple disulfide bonds often must be heated longer at higher temperatures to denature them. One such protein is bovine pancreatic trypsin inhibitor (BPTI), which has 58 amino acid residues in a single chain and contains three disulfide bonds. On cooling a solution of denatured BPTI, the activity of the protein is restored. What is the molecular basis for this property?
Solution
Part A
Disulfide bonds are covalent bonds which are much stronger than the non-covalent forces in protein i.e hydrogen bonds, weak wander vaal forces etc. Being strong in nature, the disulfide bonds causes cross linking between the chains of protein. This cross linking develops strong bonds that enhance the stiffness and hardness of the protein thereby increasing its mechanical strength. Stability increases because the entropy decreases.
Part B
The disulfide bonds with in the BPTI’s three adjacent cysteines, prevents the protein from changing its structure to any stable form and hence prevent it from folding and unfolding completely
