Do you mean diagram A compared to Diagram D?
Diagram D is different from Diagram A because Diagram D shows representations of molecules which make up compounds. Diagram A is a representation of atoms which make up elements.
You can find the air spaces in the cell of the leaves where
stoma can be located. The stoma allows
for carbon dioxide to come in, and oxygen to go out. A stoma opens into the airspace inside the
leaf. Carbon dioxide, oxygen, water vapour are the gases might you find in the
air space.
The answers;
1. Termination. Out of the 64 codons, UAG, UAA, and UGA are the stop codons that terminate translation when encountered by the ribosome. These three do not code for any amino acid but rather cause the translation complex to dislocate.
2. Translation. In this process, the ribosome ‘reads’ the codon and brings in a t-RNA with an anticodon to the codon. This tRNA carries a specific amino acid (for that codon) and engages in the P-site of the ribosome. The amino acid is taken from the t-RNA and used to elongate the polypeptide chain being formed. Thereafter the empty t-RNA dislocates.
3. Aminoacyl-tRNA synthetase. When a tRNA brings in an amino acid to the initiation complex, it is dislocated when ‘empty’. Aminoacyl-tRNA synthetase then catalyzes the reattachment of another amino acid through a chemical reaction called esterification. The cognate tRNA then become an aminoacyl-tRNA.
4. tRNA . Every tRNA has an amino acid attached to it. The type of amino acid (out of the 22 amino acids) is determined by the anticodon on the tRNA. There are many codons that are amino acids meaning that there are redundant codons that specify for the same amino acid.
5. Initiation. Initiation begins by the formation of an initiation complex. This complex is comprosed by the two subunits of the ribosome, and the mRNA. The complex becomes compelete when a Met-tRNA (a tRNA with a methionine amino acid) engages the P-site and then translation begins.
Answer:
Option B, Dd and Dd
Explanation:
It is given that deafness is a recessive trait.
Let the recessive trait be represented by "d"
Normal hearing is a dominant trait and let it be represented by "D"
It is given that Dr. Smith's parents have normal hearing , hence they can have genotype -
either Dd X DD
Or Dd X Dd
but Dr. Smith has an inherited form of deafness , thus his genotype would be "dd". Considering the genotype of Dr. Smith , his parents would be having genotype Dd and Dd.
Thus option B is correct.
