Answer: DNA is antiparallel because Its double strands run in opposite directions.
Explanation: The antiparallel nature of DNA strands means that as one strand runs in 5'->3' direction, the other strand runs in 3'->5' direction. The two antiparallel DNA strands are not identical in either base sequence or composition rather they are complementary to each other. This means that anywhere thymine base is found in one strand, adenine is present in the other strand and anywhere guanine occurs in one strand, cytosine occurs in the other strand.
Answer:
Atomic mass is defined as the number of protons and neutrons in an atom, where each proton and neutron has a mass of approximately 1 amu (1.0073 and 1.0087, respectively). The electrons within an atom are so miniscule compared to protons and neutrons that their mass is negligible.
Explanation:
All you need is :
one egg
vinegar
and a glass or bowl that is taller than the egg
tilt the glass when you put the egg in so it doesn't brake then pour vinegar in to cover the egg and watch as its shell disolves
Answer:
C) 50%
Explanation:
Let the homozygous recessive organism be rr
Let the heterozygote be Rr
If both organism crosses together: Rr × rr
= we have ( Rr, Rr, rr, rr) as their offspring.
The question says; what is the chance of producing an offspring with the homozygous recessive phenotype?
From above, the chance of producing an homozygous recessive is 50%.
i.e (2/4) × 100%
=(1/2) × 100%
= 50%
