Nucleic acids are the biopolymers, or large biomolecules, essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA . They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.
Answer:
The probability is 0.25 or 25%
Explanation:
To answer that question, you need to solve a Punnett Square. The Punnett Square allows you to observe the crossing of two parents, being able to observe the relationship between the alleles of each parent in the construction of the offspring. Punnett Square, is made on a table with eight squares. The alleles of one parent are placed in the first row, while the alleles of the other parent are placed in the first column. Therefore, each allele of one parent is combined with the allele of the other, as the remaining squares are filled. This combination of alleles leads to the genetic probability of a possible offspring.
In the case of the question above, the cross between the alleles of parents that both have the Tt (Tt x Tt) alleles is shown below, using the Punnett square.
T t
T TT Tt
t Tt tt
At this intersection, we can see that the "tt" alleles only appeared once in an offspring of 4 possibilities. Thus, we have a 1/4 calculation that is equal to 0.25, which represents a 25% probability that the offspring of this crossing will present individuals with the "tt" alleles.
DNA replication
After the process of DNA replication occurs, each daughter cell receives an exact copy of the parent cell's DNA.
DNA replication is a biological process by which a DNA molecule divides to produce two copies of itself during cell division. DNA replication takes place in all living organisms. During DNA replication, an enzyme known as helicase separates the double helix structure of the DNA molecule into two separate strands which serve as templates for making the new strands of DNA.
Answer:
a) Digestive System
b) Sweat Glands
c) Reproductive system
Explanation:
In a teenage child, the body systems which get most affected by the cystic fibrosis other than respiratory system are
a) Digestive System
b) Sweat Glands
c) Reproductive system
However, it has not yet been very strongly proved but to some extent it is believed that CF even affect the nervous system
Nervous system - It is believed that CF mutation may directly affect the nervous system by causing neural abnormalities.
