Question

12. If the sequence of one strand of DNA is ACCTGA, that the sequence in the other strand would be: a TGGACT b UGGACU c CGGAUC d TAAGCT 13. What is the product of meiosis in an animal cell? a Gametophyte b Spore c Gamete d Sporophyte 14. What organelle serves to package and transport molecules throughout the cell? a Mitochondrion b Golgi apparatus c Nucleus d Ribosome 15. What process describes the release of materials across the cell membrane? a Phagocytosis b Exocytosis c Active transport d Pinocytosis 16. What part of cell regulates the passage of substances into and out of the cell? a Golgi apparatus b Smooth endoplasmic reticulum c Nucleus d Cell membrane 17. How many chromosomes would be present in the gametes of a diploid organism with chromosome number of 46? a 46 b 69 c 23 d 92

Explanation / Answer

12. Ans-a TGGACT

In DNA strand, the nitrogen bases which complementary to each other are A-T and C-G. Therefore, the other strand is TGGACT.

13. Ans- c. Gamete

During meiosis division, each homologous chromosome produced new "gamete".

14. Ans- b Golgi apparatus

Golgi apparatus act as a packing and distribution center.

Mitochondrion is called powerhouse of cell

Nucleus act as a carrier of genetic information

Ribosome involved in protein synthesis

15. Ans- b. Exocytosis

Exocytosis – It is a process of release of large particles across the cell membrane.

Phagocytosis is the process of engulfing of bacteria and other microbes.
Active transport is a movement of material against the concentration gradient

Pinocytosis is the process of uptake of fluid and any small molecules.
