Compare the structure of DNA and RNA and complete the table suitably. Number of strands Type of sugar Nitrogen bases DNA RNA

Number of strands Type of sugar Nitrogen bases DNA Two Deoxyribose Adenine, Thymine, Guanine, Cytosine RNA One Ribose Adenine, Uracil, Guanine, Cytosine DNA is a double stranded structure made of deoxyribose sugar, pentose phosphate and nitrogen bases. The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. RNA is single stranded structure composed of ribose sugar, phosphate and nitrogen bases. RNA converts the information stored in DNA into proteins.

Arrange the stages of protein synthesis in the form of a flow chart. protein synthesized by adding amino acids mRNA reaches ribosomes mRNA is formed amino acids are carried to the ribosomes

The arrangement pf stages of protein synthesis are as follow: mRNA is formed 🠗 mRNA reaches ribosomes 🠗 amino acids are carried to the ribosomes 🠗 protein synthesized by adding amino acids. Proteins are made of different types of amino acids. The whole process of protein synthesis starts with the formation of mRNA from DNA. mRNA leaves the nucleus and reaches the ribosomes. Besides mRNA, there are tRNA that carries amino acids to the ribosomes. Protein molecules are synthesized by the activities of all these molecules.

Observe the hybridization experiment given below. Illustrate this hybridization experiment using symbols.

When plants that differ in a pair of contrasting traits are hybridized, only one trait is expressed while the other remains hidden in the offsprings. The expressed trait is called the dominant trait and the hidden trait is called the recessive trait.

Observe the hybridization experiment given below. Illustrate the second generation formed by the self-pollination of first-generation plants.

When the F1 generation's plant self-pollinated, most of the plants in the F2 generation has green coloured seeds as green colour is dominant over yellow coloured. The ratio of the result obtained is approximately 3:1. It means out of four plants three are with green seed and one is with yellow seed.
