<span>The mutation did not affect amino
acid sequence or the molecular weight (no evidence of amino acid substitution
or protein truncation). Therefore, the mutation is not likely within the coding
region of the gene. Most likely the
mutation is in the regulatory region of the gene such as the promoter region.
Such mutation would interfere with transcription initiation and hence decreases
the amount of mRNA and protein produced. </span>
Answer:
Red blood cells makes up your body
The organic pathway of the carbon cycle moves from atmosphere through other organisms back to the atmosphere
True. This refers to principles of physics where an atom can neither be created nor destroyed. An atom exists to create specific elements that are found within the Earth. Its particles are only disrupted when such nuclear fusion and fission are applied in a controlled environment.
Answer:
The chance that their <u>child will not be able to roll his tongue will be zero</u>.
The chances to have a child with tongue rolling ability is 100%.
Explanation:
In complete dominance, a dominant gene completely manifests over a recessive gene. If tongue rolling is a dominant trait, this means that the gene that expresses this trait is dominant over the recessive one that does not allow the person to roll the tongue.
If the gene for tongue rolling is called T, then a person that is homozygous dominant for this trait will have the following genotype: TT. If the person is heterozygous for this trait, the genotype will be Tt. And if a person is homozygous recessive for the trait, this person´s genotype will be tt.
When two homozygous dominant individuals mate, their chances to have a child with tongue rolling ability is 100%.
This is:
Parental) TT x TT
Gametes) T T T T
Punnet Square) T T
T TT TT
T TT TT
F1) Genotype: 100% TT, or 4/4 TT
Phenotype: 100% Tongue rolling capable.
