BIOLOGICAL TERMS: PAPER 2
Give the correct biological term for the following descriptions.
DESCRIPTIONS BIOLOGICAL TERM
1. An allele that does not influence the phenotype
when found in the heterozygous condition.
2. The position of a gene on a chromosome.
3. The physical and functional expression of a gene.
4. Chromosomes that are not responsible for sex
determination.
5. The process of finding a desirable gene, isolating
it and then moving it into the cells of another
organisms.
6. The two parts of a chromosome held together by
a centromere.
7. A section of a DNA molecule that codes for a
specific characteristic.
8. The production of genetically identical copy of an
organism using biotechnology.
9. The deliberate breeding of organisms for
desirable characteristics selected by humans.
10. The explanation that species experience long
periods without physical change, followed by short
periods of rapid physical change.
11. The phase of meiosis during which homologous
chromosomes separate and start moving towards
opposite poles.
12. The defect in cell division that leads to Down
syndrome.
13. The structure that is made up of two chromatids
joined by a centromere.
, 14. An explanation for something that has been
observed in nature and which can be supported by
facts, laws and tested hypotheses.
15. Similar structures on different organisms that
suggest they have a common ancestor.
16. The complete set of chromosomes in the cell of
an organism.
17. A bar code pattern formed from DNA.
19. The bonds formed between amino acids.
20. A representation of the number, shape and
arrangement of all the chromosomes in the nucleus
of a somatic cell.
21. Openings in the nuclear membrane that allow
mRNA to leave the nucleus.
22. A tentative explanation of a phenomenon that
can be tested.
23. The distribution of species in different parts of
the world.
24. Chromosomes that carry the same set of genes.
25. Two or more alternative forms of a gene at the
same locus.
26. The structure responsible for pulling
chromosomes to the poles of an animal cell during
cell division.
27. A phase in the cell cycle that occurs before cell
division.
28. A diagrammatic representation showing
possible evolutionary relationships among different
species.
29. The type of vision shared by apes and humans
that allows for depth perception.
