Quiz 1A - Answers
1) Where is the genetic information contained in cells?
The genetic information for cells is contain in chromosomes.
2) The cell membrane is partially permeable. What does a partially permeable membrane mean?
A partially permeable membrane means that some substances can pass through the membrane and other substances cannot pass through the membrane. Small substances are able to pass through the membrane and larger substances are unable to pass through the membrane.
3) What are the 3 components that a plant cell has that a human cell does not have?
Cell wall, chloroplasts and a permanent vacuole
4) What component in the cell is responsible for most the respiration reaction?
They are responsible for some of the chemical reactions that take place in respiration and respiration releases energy that the cell can use. Cells that require a lot of energy have a lot of mitochondria.
5) What do ribosome do?
Ribosomes are responsible for assembling proteins for the cell.
6) What is the cytoplasm?
The cytoplasm is a gel-like substance that makes up most of the cell. It is made up of many different substances.
7) What component of plant cells is responsible for photosynthesis?
Chloroplasts are responsible for photosynthesis in plants
8) DNA is ______ strands of nucleotides coiled together to form a ________ helix
Two, double
9) Each strand in DNA contains 3 components. What are they?
Each strand contains a nitrogenous base, a sugar molecule and a phosphate group.
10) What are the nitrogenous bases?
The nitrogenous bases are adenine (A), thymine (T), cytosine (C) and guanine (G).
11) What does complementary bases mean?
A complementary base means that the bases will only bind with other and never any other bases.
12) What is the complementary base to adenine?
Thymine
13) What is the complementary base to guanine?
Cytosine
14) A section of one allele for hair colour has the DNA sequence:
GCTTATGAACGGA
What is the complementary DNA strand?
CGAATACTTGCCT
15) What component of the cell is DNA found?
The nucleus
The genetic information for cells is contain in chromosomes.
