The correct answer is: a. using a photographic negative to make a positive image
A negative image is a total inversion of positive image (normal image). Negatives are normally used to make positive prints.
This can be compared to copying mechanism of DNA-replication of DNA in which one strand of DNA (e.g. 3’-5’ orientation) is used as a template to make new strand with opposite orientation (5’-3’).
Option C:
B. wild-type 5-AUGCAUACAUUGGAGUGA-3 mutant 5'-AUGCAUACAUCUGGAGUGA- 3'
Explanation:
A frameshift mutation is a genetic mutation such that the triplet nature of gene expression by codons, the insertion or deletion occurs in such as way that it alters the complete sequence of 3 codon sets and can change the reading frame, resulting in a completely different translation from the original.
As it is pertinent to understanding that all genes are normally translated in sets of 3 codons, which typically describes and explain a unique amino acid sequence. Thus, if a frame shift mutation occurs, it can affect many amino acid sequences and finally the entire protein.
If we look at option B:
wild-type 5-AUG CAU ACA UUG GAG UGA-3
mutant 5’- AUG CAU ACA UCU GGA GUG A-3’
An insertion of a base Uracil showed at the end of 3rd codon which affected and altered the whole sequence of codon triplets. This changed all next codons and finally all next amino acids will be altered.
Aorta to: arteries, capillaries, venules, veins, superior/inferior Vena Cavae, to Right atrium of the heart, through the tricuspid valve(or called the right AV valve) into the Right ventricle, then pushed through the Pulmonary valve into the Pulmonary trunk and then off into the Pulmonary-Arteries ( to the lungs), then to Pulmonary arteries( which bring blood back to the heart), then into the Left atrium through the Mitral valve into the Left Ventricle, which pushes blood through the Aortic Valve then back to the Aorta!
There is your detailed answer in order! :) yay!!
Just imagine the process in your head. Once you trace it with your mind it is easy to follow!
Good luck and I hope I helped.
These cells consume bacteria and other pathogens to protect the body from infection. The process begins when chemicals from a pathogen, or damaged tissue, attract a phagocyte. The phagocyte binds to the microbe, envelopes it, and then eats it.
