Answer: Smallpox
Explanation: Small pox is an ancient disease which is caused by the Virus named as Variola virus. Early symptoms are fatigue and high fever.
The virus then after produces rash on faces arms and legs. The spots gets filled with fluid and pus and in later stages it turned into crust.
This crust eventually dried and falls off. It was fatal in almost 30% of the cases.
It eradicated by a collaborative global vaccination program which was led by WHO.
An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication. This can happen when the replicating strand "slips," or wrinkles, which allows the extra nucleotide to be incorporated (Figure 2). Strand slippage can also lead to deletion mutations. I’m not sure if this right but I tried
Answer:
E
Explanation:
In DNA molecule, the number of guanine bases will always be equal to the number of cytosine bases. Genuine make a triple hydrogen bond with cytosine. That's why the number of guanine bases is equal to cytosine bases.
Answer:
The genotype for each of the parents must be
parent 1 : Gg
parent 2 : Gg
Explanation:
Please note that a dominant trait is a trait that is expressed phenotypically in a heterozygous state, while a recessive trait is a trait that can only be expressed in a homozygous state.
Now, since gray face (G) for Oompa Loompas is dominant, and orange face (g) is recessive, for an offspring to be orange faced, it means that the genotype of the offspring must be 'gg'. Also, since both parent contribute an allele in the pair of alleles in the offspring, both parents must have the recessive (g) in their genotype. Moreover, we are told that both parents are gray-faced, meaning that their genotypes were 'Gg' and 'Gg'. To confirm, let me do the cross
G g
G GG Gg
g Gg gg
from the cross above, we find out that out of 4 offspring, 3 were gray face (GG, Gg ) while one was orange face (gg).
