DNA has D-ribose is incorrect statement. DNA contain deoxyribose sugar, it is also know as pentose sugar. (here \(\mathrm{D}\) is denoted for \(\mathrm{D}\)-ribose sugar not for deoxyribose nucleic acid ). D-ribose is the molecule appearing in RNA. - All monosaccharides (glucose, fructose, galactose) are reducing sugars because they either have an aldehyde group or can tautomerise in solution to form an aldehyde group. - Cellulose is a polysaccharide composed of a large number of \(\beta\)-D-Glucose units. In cellulose \(\beta\)-Dglucose units are joined by \(\beta-1,4\)-glycosidic linkage. - Amylopectin is even less soluble due to the additional 1,6-glycoside bonds on the branch chains, further reducing its \(\mathrm{H}\) bonding potential and therefore reducing solubility in water.

Which statement is wrong about satellite?
1 They show high degree of polymorphism
2 They do not take part in protein synthesis
3 They do not inherit from parents to offspring
4 None
Explanation:
Satellite DNA, also known as satellite sequences, refers to a type of repetitive DNA found in the genomes of many organisms, including humans. It is characterized by short, highly repetitive sequences of nucleotides that are repeated in tandem. Satellite DNA is typically found in non-coding regions of the genome, meaning these sequences do not code for proteins. They inherit from parent to offspring.

If one strand of DNA has the nitrogenous base sequence as ATCTG, what would be the complementary RNA strand sequence?
1 AACTG
2 ATCGU
3 TTAGU
4 UAGAC
Explanation:
In RNA thymine base is replaced by Uracil. Hence, {ll} |ATCTG | (Templete DNA) | |---|---| |TAGAC | (Coding DNA strand) | |UAGAC | (Complementary RNA) Thus, the RNA strand complementary to DNA strand ATCTG will be UAGAC.

Segments of DNA which can move in genome
1 Transposons
2 Introns
3 Exons
4 Cistrons
Explanation:
The segment of DNA, which can move in a genome is a transposons. - It is a segment of DNA that is capable of moving into a new position within the same or another chromosome, called jumping gene.
DNA has D-ribose is incorrect statement. DNA contain deoxyribose sugar, it is also know as pentose sugar.
