Answer:
tissue
Explanation:
a tissue is a group of cells that work together to perform a common function
This is a typical case of a dihybrid cross.
From the phenotype of the offspring, we can conclude that the gene for the red color of the flower and the gene for the axial position of the flower are dominant.
Since we know that the ratio of phenotypes in a dihybrid cross of independently inherited alleles is
9(dominant for both traits)
3(dominant for one trait, recessive for the other)
3(dominant for the second trait, recessive for the other)
1(recessive for both traits)
we can expect 3/16 of the f2 generation to be dominamt for one trait and recessive for the other (red, terminal flowers), or to be precise 190 individuals.
Answer:
The correct answer will be option-B.
Explanation:
Deoxyribose nucleic acid or DNA is the genetic material of the organism which is made up of nucleotide monomer. The structure of DNA is made up of two strands of nucleotides coiled in a helical structure thus providing a double-helical shape to the structure.
Each nucleotide of a strand is composed of a five-carbon sugar, phosphate group and nitrogenous bases. These molecules are arranged in anti-parallel fashion in DNA which provides the polarity to the DNA strand. One strand is read from the 5' to 3' direction whereas another form 3'to 5' direction.
Thus, Option-B is the correct answer.
