<span> polymerases, of which there are many. Understanding which types of polymerases perform which functions under which circumstances will clarify the complexity of this topic. The processes of transcription, making RNA from DNA, and replication, copying DNA from DNA, are major functions that require polymerases to link nucleotides into long chains. </span>
Cross of true breeding dominant and recessive tomato plants will have:
Phenotype ratio in F1 generation is 4:0
genotype ratio in F1 generation is 4:0.
Explanation:
Data given:
Tall vine = dominant TT
dwarf vine = recessive tt
red fruit dominant RR
yellow fruit recessive rr
true breeding tall tomato plant bearing red fruit is TTRR
true breeding dwarf tomato plant bearing yellow fruit = ttrr
the cross is shown in punnet square:
TR TR
tr TtRr TtRr
tr TtRr TtRr
the phenotype ratio- 4:0
the genotype ratio - 4:0
The phenotype is tall vine with red fruit
Genotype is all the progeny are heterozygous dominant.
Answer:
λ = 37 nm
Radiation is in the ultra violet region.
Explanation:
Given data:
Energy of photon = 5.44 × 10 ⁻¹⁸ J
Wavelength of photon = ?
Solution:
E = h.c / λ
λ = h. c/ E
λ = 6.63× 10⁻³⁴m² kg/s × 3×10⁸ m/s / 5.44 × 10 ⁻¹⁸ Kg m²/s²
λ = 19.89 × 10⁻²⁶ kg. m³ /s² / 5.44 × 10 ⁻¹⁸ Kg m²/s²
λ = 3.7 × 10⁻⁸ m
m to nm conversion.
λ = 3.7 × 10⁻⁸m ×10⁹ nm / 1m
λ = 37 nm
Radiation is in the ultra violet region because the rage of UV is 1 nm - 400 nm.
Planet X
Explanation:
The orbital radii of planet X is the smallest which means that is closest to the sun. The distance to the star determines the temperature of the planet. Closer the planet, more likely it would have higher temperature. So planet X has highest temperature most likely.
In the solar system, there is exception, mercury is closest to sun but Venus which is the second planet from the sun has highest temperature. This is because mercury has no atmosphere and Venus has very thick atmosphere which traps the solar radiation and heats up.
