Explanation:
Introns are non-coding regions of a DNA that removed by RNA splicing prior to translation. Alignment is usually done between sequences to see and understand the identity and similarity between two or more sequences.
A region/base is said to be conserved if there is NO change in any base in that particular region. A multiple sequence alignment (MSA) can be used to align the donor sites of all the introns to see the bases that have not "changed" (and still remained in there exact position) hence conserved across all the donor sites.
NOTE: The donor site of an intron is the 5' end, thus the first five bases in the 5' end are to be used here
Answer:
The correct answer is b. The oldest generally accepted fossils of large animals range in age from 565 to 550 million years old.
Explanation:
The oldest one of them all is the hematite tubes, that are dated about 3.77 billion to 4.2 billion years and it's from a yet unknown bacteria.
I think it might be possible because they took the nucleus from a sheep and put it inside a sheep embryo and it made an exact clone of the sheep.If they could make a nucleus that could handle the DNA of the dinosaurs and have the nucleus function properly and have the embryo grow properly then it might be possible for them to create dinosaurs.
The organelle that could b malfunctioning is the mitochondria, which packages proteins and without protein for cells, the outcome is cell lysis, or destruction.
Answer:<u> Infection caused by specific round shaped bacteria called staphylococcus. </u>May also be dangerous or life threatening and can last several weeks or months
