Answer:
<h2>5'-UCAAUGC-3'</h2>
Explanation:
According to base pairing rule of DNA and RNA, A is always pairs with T ( in case of DNA) or with U ( in case of RNA) with two hydrogen bonds(A=T), and C is always pairs with G in both DNA and RNA with three hydrogen bonds ( C≡G).
As given here, one segment of RNA molecule containing sequence 5'-GCAUUGA-3', so as the rule, G always binds with C and so on, so the sequence of the binding segment would be 3'-CGUAACU-5'. it can be written as 5'-UCAAUGC-3'
Answer and Explanation:
cross: BbTt x bbTt
<u>Cross for B gene</u>
Parental ) Bb x bb
Gametes) B b b b
Punnet square) B b
b Bb bb
b Bb bb
F1) Genotypic proportion: 2/4=1/2 Bb : 2/4=1/2 bb
Genotypic ratio 1:1
Phenotypic proportion: 2/4=1/2 B- : 2/4=1/2 bb
Phenotypic ratio 1:1
<u>Cross for T gene</u>
Parental ) Tt x Tt
Gametes) T t T t
Punnet square) T t
T TT Tt
t Tt tt
F1) Genotypic proportion 1/4 TT
2/4 Tt
1/4 tt
Genotypic ratio 1 : 2 : 1
Phenotypic proportion: 3/4 T-
1/4 tt
Phenotypic ratio 3 : 1
The answer should be A. A controlled nuclear chain reaction produces heat, driving steam turbines to produce energy.
Answer: angular distance north or south from the celestial equator measured along a great circle passing through the celestial poles
Explanation:
Biodiversity is essential in medicine as most active chemicals used to make medicines are derived from plants or other organisms. Climate change today threatens species that are vital to medicine. An example would be coral reefs. Studies have been done on reefs that look at fighting cancers, HIV and other ailments. One of the richest zones of biodiversity is the tropics and this region is under threat from global warming and deforestation. It is important to preserve these species for use in future medicinal research. <span />
