Consider the following statements: (a) DNA is a long polymer of ribonucleotides (b) only one strand of DNA acts as a template for the synthesis of a new strand of DNA during replication (c) tRNA is also called adaptor molecule (d) DNA performs both autocatalytic and heterocatalytic functions. Which of the given statements are correct?

Which of the following statements regarding transcription are correct? Br a. Transcription governs the principle of complementarity. Brb. If both strands of DNA act as a template, they would code for RNA molecule with same sequences. Br c. Double stranded RNA formed after transcription promotes RNA from being translated into protein. br d. Like the process of replication, the total DNA of an organism gets duplicated in transcription also

Assertion :- Complementary base pairing confers a very unique property to the DNA chains. Reason : If sequence of one strand is known then sequence in other strand can be predicted.

Explain the following : (i) Amino acids behave like salts rather than simple amines or carboxylic acids. (ii) The two strands of DNA are complementary to each other.

Read the following statements. Statement A: In agarose gel electrophoresis, the smaller the fragment size of DNA, the farther it moves from the wall. Statement B: Separation of proteins in normal electrophoresis is based on both size and charge. Choose the correct option.

Go through the following statements: (i) Viruses are obligate parasites (ii) Viruses that infect plants in general have single stranded DNA (iii) Bacteriophages are double stranded DNA viruses. (iv) The coat is made of protein subunits called nucleomeres. Find the correct statements

Read the sequence of the nucleotides in the given segment of mRNA and the respective amino acid sequence in the polypeptide chain. Polypeptide: met-phe-met-pro-val-ser Write the nucleotide sequence of the DNA strand from which this mRNA was transcribed.

Assertion: Three main types of restriction endonucleases, i.e., Type I, Type IT and Type ill are known with slightly different modes of action. Reason: In palindromes with rotational symmetry, second half of complementary strand in a DNA double helix is the mirror image of base sequence in the first half of another strand.

Read the following statements regarding agarose gel electrophoresis and select the CORRECT ones. I. The longest DNA fragments are nearest to the anode. II. The matrix of the gel is a natural polymer obtained from seaweeds. III The process is used to check the progression of restriction enzyme digestion. IV. The fragments of DNA separated due to the sieving effect provided by agarose gel.
