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.
Answer:
The correct answer is C) 5"-CCTCAGG-3"
Explanation:
Palindromic sequence is a that remain same when read from front side as well as from the back side.
Such as MADAM,ROTOR
In the given question option C is not a palindromic sequence beacuse when we read from frontside it is
5"-CCTCAGG-3"
But when we this this same sequence from the backside it becomes
5"CCTGAGG-3"
Answer: A
Explanation: PCR help to create multiples of copies, it can produce millions of copies of DNA sequence in a test type in limited or few hours. PCR has revolutionize molecular biology, and it has become an essential tools for biologist, physicians or anyone who really want to work on the DNA.
