Answer:
<h2>3/16</h2>
Explanation:
As given;
Brown coat color (B) is dominant over (b), so B is dominant over b.
Solid color (S) is dominant over the spotted(s), so S is dominant over s.
crossing between true breeding brown, solid colored guinea pig( BBSS) with red spotted pig( bbss)
so parents are BBSS× bbss
gametes are, of parent-1; BS, and parent-2: bs
F1 is : BbSs,
cross between F1 and F1
F2 is : BBSS, BBSs, BbSS, BbSs............BBss..........Bbss........bbSS.......bbss etc
So red and solid color offspring are (bbS_) = 3/16

The endosymbiont theory explains the origin of the eukaryotic cell organelles where the cells were engulfed but not digested by the larger prokaryotic cells and in the process developed into the chloroplast, mitochondria and other organelles.
(A) The theory was trying to explain the evolutionary origin of the various cell organelles and,
also explains the dependence of cells on one another.
(B) The evidences that supported the Endosymbiotic theory includes;
-The photosynthetic bacteria; This bacteria utilize the sun's energy to make energy hence the oxygen released from the process accumulated in the atmosphere thereby leading to the death of the anaerobic cells.
-Organelles have their own DNA and divide independently, therefore Margulis predicted that if the organelles were really prokaryotic symbionts, then they would have their own DNA.
- The study of fossils showed the aerobic cells in it, therefore the cells could use the toxic oxygen and convert it into ATP(energy) and water. Organisms that could thrive in aerobic environments were now best suited to the environment.
Answer:
3'-GCTATAACTCGATTCGAA-5'
Explanation:
The DNA is a macromolecule formed by two strands of polynucleotides forming a double helix.
These chains are composed of monomers called nucleotides, there are 4 different types in DNA, called nitrogenous bases: two purines, guanine (G) and adenine (A) and two pyrimidines, thymine (T) and cytosine (C). They are joined by covalent bonds in each chain.
These bases are complementary: G with C, and A with T between the two strands by hydrogen bonds making the double-stranded DNA molecule.
A sequence 5'-CGAT-3' is equivalent to a sequence written 3'-ATCG-5' , because the 5' and 3' notation defines the direction of reading. If one strand is noted 5' to 3', then the complementary strand will be from 3' to 5' in the same sense.
So, all we need to do is write the complementary bases from the 3' end to 5':
5'-CGATATTGAGCTAAGCTT-3'
3'-GCTATAACTCGATTCGAA-5' (answer)
