During the first 2-3 weeks you will not see any physical signs. Look at your dog's nipples, for if it is pink, that may be an indication. Be sure to observe your dog's body and it's weight.
Answer:
D. Many amino acids are encoded by multiple codons. A gene mutation that encodes the same amino acid would have no observable effect on the cell or the organism
Explanation:
If gene mutation does not change code (gene still encodes for the same amino acid), the same protein with its function will be produced. This is called synonymous mutation.
Silent mutations might also occur when codon is altered to produce an amino acid with similar function as previous (e.g. leucine to isoleucine) so that the function of protein is not significantly changed.
Answer:
Option). Increasing enzyme, increasing substrate, increasing co-factors
Explanation:
Enzymes are bio-catalysts that increase the rate of a chemical reaction by decreasing its activation energy. As enzymes are catalytic molecules, increasing enzyme concentration would increase rate of reaction.
Substrates are those substrates that react with other molecules to form products. Thus, increasing the concentration of substrates, along with enzymes to an enzyme-catalyzed reaction would increase rate of that reaction.
Co-factors are non-protein compounds or ions, which are required for proper functioning of many enzymes. Thus, increasing the concentration of co-factors, along with enzymes to an enzyme-catalyzed reaction would increase rate of that reaction.
Thus, the correct answer is option). 'increasing enzyme, increasing substrate, increasing co-factors.'
Answer:
XbY
Explanation:
The gene responsible for colorblindness is written as Xb since it is present on the X chromosome. In humans, sons get their X chromosomes from the mother while inheriting the Y chromosome from the father. In the given cross, the genotype of the colorblind mother would be XbXb (the X-linked recessive traits such as colorblindness are expressed in homozygous conditions in females).
She would transmit one copy of "Xb" to her son. The genotype of the father would be "XY" and he will give "Y chromosome" to the son. Therefore, the genotype of the son would be "XbY".
