Well,
By the word "deletion" we can deduce that information is lost. Therefore, when a chromosome undergoes a deletion mutation, information is lost. This can have disastrous effects if it is a human chromosome.
Answer:
a) Yes
b) Yes
c) Yes
d) Yes
Explanation:
a.
In the exons?
Yes mutant site will be expected. It will transcript-ed as well and it can be a polypeptide depending on the mutation type.
b.
In the intron?
Yes mutant site will be expected. It will be transcript-ed as well and it cannot be a polypeptide
c.
In the promoter?
Yes mutant site will be expected. It will not be transcript-ed and it cannot be a polypeptide
d.
In the intron-exon boundary?
Yes mutant site will be expected. It will be transcript-ed and it cannot be a polypeptide
Answer:
D. 1 BB : 2 Bb : 1 bb
Explanation:
This question involves a single gene coding for fur color in guinea pig. Black fur (B) is dominant over white fur (b). This means that, as stated in the question, if a black fur parent (BB) is crossed with a white fur parent (bb), a 100% heterozygous offspring (Bb) with black fur will result.
If two heterozygous guinea pigs are crossed i.e. Bb × Bb, the following gametes will be produced by each heterozygous parent:
Bb = B and b
Using these gametes in a punnet square (see attached image), offsprings with the following genotypic ratio will be produced:
1 BB : 2 Bb : 1 bb
BB and Bb = black fur guinea pigs
bb = white fur guinea pigs
Answer:
Petiole
Explanation:
The petiole is the part of the leaf that attaches the leaf to the main stem of the plant. Depending on the leaf structure of the plant, some leaves may be devoid of a petiole, and be regarded as apetiolate.
Answer:
Africa or any middle Asia
Explanation:
Because the weather is dependent on the sun... In the morning when there is sun, it gets much hotter and warmer...
In the night when the sun is gone the temp gets little lower and make it colder
