The minimum legth of a codon could be two. If it was only one of the 6 nitrogeneous bases in a codon, we'd only have 6 possible amino acids. If we have, though, a combination of two amino acids out of the 6 nitrogeneous bases, we would have then 36 possible combinations (6 possibilities for the first position × 6 possibilities for the second position) that would allow the existence of the 20 different amino acids.
In the human case, for example, with only 4 nitrogeneous bases, a combination of two amino acids would be insufficient (4×4=16) for the 20 amino acids.
Answer:
13
Explanation:
The atomic number for Aluminum (Al) is 13. If you have access to the periodic table, this would've taken a few seconds.
The cross of heterozygous
AaBb as parental phenotype led to formation of 1
6 phenotype of the offspring.This is because this is dihybrid form of inheritance .The probability of having
aabb offspring is
1/16 since there is only one aabb type of offspring phenotype out of
the
16. An illustration of how crossing is done is as per punnet square below
The best choice is uneven heat distribution because If a place has a warm are it has low pressure and if it has a cold area it has high pressure.
Wind moves from areas of high air pressure to low air pressure.
Example: Land Breeze and Sea Breeze.
Th earth has uneven distribution due to different angles of insolation and by earth tilts.
In the text it says “Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. ... In the process, a water molecule is formed.” I hope this helped
