Cytosine. This is because Guanine ALWAYS bonds with Cytosine in DNA
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:
B) rough ER → Golgi complex → Golgi vesicle → extracellular fluid
Explanation:
- Insulin is synhtesized by beta cells of pancereas (preproinsulin).
- Insulin enters the rough endoplasmic reticulumn in its inactive form (proinsulin).
- The rough endoplasmic reticulumn converts it to active form (insulin).
- The rough endoplasmic reticulumn transfer the insulin to glogi comlpex
- The Golgi complex secrete it in golgi vesicles to cytoplasm.
- On the stimulation of beta cells insulin is secreted to extracellular fluid..
4^3 = 64
There are 64 ways to arrange the four bases (Adenine, Thymine, Cytosine, and Guanine) into triplets (include repeats of bases as well, for e.g. AAT).
Just in case you are confused by my use of Thymine above, one thing to note is that Thymine will be replaced with Uracil in RNA.
Hope this helps! :)
Answer:
C
Explanation:
The production of ATP is greatest at 50o C as indicates by the production of CO2 in the Krebs Cycle
