Answer:
B) A -1 base pair deletion shortly after the start codon.
Explanation:
A base pair deletion right after the start codon will block the protein function because it will cause the entire reading frame to shift. Therefore the protein which will be synthesized out of such mRNA will be non-functional because it will be entirely different from that of the original protein.
In other options, the protein synthesized will not be this much different from the original protein and hence it will be functional although the efficiency of the protein will be less as compared to original protein.
The protein which will be synthesized as described in option A will be same as of original protein because a base pair insertion after stop codon does not impact the protein composition at all.
The protein which will be synthesized as per option c will have only one amino acid difference as compared to the original protein so it will be functional. Similarly the protein synthesized as per option D will also be functional because the only amino acid which will be different from the original protein will be the last amino acid of the polypeptide and hence will not affect the function of protein adversely.
Answer: Hydrogen bonds
Explanation: The CAS9 enzyme affect the bond between the deoxyribose sugar and the phosphate backbone of the PAM sequence in the target DNA
Explanation:
surface of Afghan people crowding airports and clambering on top of planes in the hope of fleeing the Taliban takeover of Afghanistan, politicians and veterans in the U.S. are joining a mounting wave of criticism calling this President Joe Biden's "Saigon moment."
Biden told reporters last month the U.S. troop withdrawal from Afghanistan would not be comparable to what occurred when the capital of South Vietnam fell to the North Vietnamese in late April 1975. But the speed with which the Taliban triggered the collapse of the Afghanistan government and the evacuation of the U.S. Embassy in Kabul has led many to draw those comparisons.
Biden announced in April his administration aimed to finish its planned U.S. troop withdrawal before the end of the summer. As the months ticked past, the Taliban expanded its reach in the country by capturing major provinces and continued to escalate its efforts through the last week.
Over the weekend, the Taliban surrounded Kabul, Afghanistan's capital city, and completed its takeover. U.S. State Department officials said people working in the U.S. Embassy were successfully evacuated to the Hamid Karzai International Airport.
Answer:Comparisons are being drawn between the fall of Saigon in 1975 and the fall of Afghanistan following the recent collapse of the Afghanistan government. Above, Afghan people climb atop a plane as they wait at the Kabul airport in Kabul on Monday after a stunningly swift end to Afghanistan's 20-year war, as thousands of people mobbed the city's airport trying to flee the group's feared hardline brand of Islamist rule.
Answer:
Certain photosynthetic members of the Kingdom Protista have developed a specialized structure to help them detect light. The name of this structure is eyespot
Explanation:
In euglena, which is an example of protista uses the eyespot to detect light. Members of this group possess both plant and animal characteristics
Ribosomes consist of two major components: the small ribosomal subunits, which read the RNA, and the large subunits, which join amino acids to form a polypeptide chain.
