Identify the correct order of organisation of genetic material from largest to smallest.

(1) Chromosome, gene, genome, nucleotide

(2) Genome, chromosome, nucleotide, gene

(3) Genome, chromosome, gene, nucleotide

Satellite DNA is important because it

1. codes for protiens needed in cell cycle

2. shows high degree of polymorphism in population and also the same degree of

polymorphism in an individual, which is heritable from parents to children

3. does not code for protiens and is same in all members of the population

4. codes for enzymes needed for DNA replication.

In sea urchin DNA, which is double stranded 17% of the bases were shown to be

cytosine. The percentages of the other three bases expected to be present in this DNA

are

1. G/34%, A/24.5%, T/24.5%

2. G/17%, A/16.5%, T/32.5%

3. G/17%, A/33%, T/33%

4. G/8.5%, A/50%, T/24.5%
