Explanation:
Mirror neurons are activated by performing an action or seeing another perform the action. They were found by chance during experiments with monkeys, when researchers discovered that the same neurons that fired while performing a behavior also fired while observing the behavior. Mirror neurons have been linked to motor skill development, imitating another's behavior, feeling empathy for another, understanding or comprehending social behavior, and language development. Answer for E2020
Answer:
1/16
Explanation:
Sickle-cell disease is caused by a homozygous recessive genotype <em>dd</em>.
A man and a woman both heterozygous Dd will have the following offspring:
The probability of having a <em>dd</em> child with Sickle-cell disease is 1/4. Each time they have children the gamete combination is random, so the genotype of the second child is independent from the genotype of the first child.
According to rules of probability, if two events are independent from each other, the probability of both happening is calculated by multiplying the individual probabilities of each.
Therefore the probability of having the first two children with the disease is 1/4 x 1/4 = 1/16.
Answer:
The correct answer is nitrogen base
Explanation:
The nucleotide sequence of one codon differ from that of another codon by the presence or absence of specific nitrogen base.The nucleotide sequence of different codons contain different nitrogen bases.
As a result change in genetic code result from the change in the nitrogen bases of the codons present in the genetic code.
In simple words change in single nitrogen base of a codon will change the entire codon.
