Explanation:
What type of mutation has occurred in the following example?
Original DNA Sequence ATC GGC TAG GCA
Mutated DNA Sequence
ATC AGG CTA GGC
A) deletion mutation
Answer:
A) altering the nucleotide sequence of the DNA fragment
Explanation:
Gel electrophoresis is a technique to separate the DNA fragments on the basis of their charges and size. DNA fragments are made to migrate through a gel in an electric field. DNA has nucleotides and the presence of phosphate groups makes it a negatively charged molecule. In the gel electrophoresis, DNA fragment migrates through the gel toward the positive pole. Also, the gel slows down the large molecules more than the small molecules. Therefore, the DNA fragments are separated by size. However, the sequence of the nucleotide of DNA fragments does not affect the rate of their migration in the gel.
the forelimb help with balance and crawling and the hind limbs are stroger than the forelimbs and they are used for jumping/hopping
They're strong and are good at keeping the sea out long-term, however they're really expensive
Answer:
common ancestor
Explanation:
A single specie from which other organisms have descended is called a common ancestor.
All descendants which are further generations can trace their origin from this ancestor.
- Two or more descendants can trace their origin to an ancestor.
- Most times, in a family tree, the common ancestor is usually placed on top.
- Several descendants can have just a single ancestor.
