In these cells, DNA molecules are short, circular and not associated with proteins.
In the nucleus of these cells, DNA molecules are very long, linear and associated with proteins, called histones.
Together a DNA molecule and its associated proteins form a _____________
The___________________ of eukaryotic cells also contain DNA which, like the DNA of prokaryotes, is short, circular and not associated with protein.
The___________________ of eukaryotic cells also contain DNA which, like the DNA of prokaryotes, is short, circular and not associated with protein.
base sequence of DNA that codes for: the amino acid sequence of a polypeptide a functional RNA (including ribosomal RNA and tRNAs).
A gene occupies a fixed position, called a ____________, on a particular DNA molecule.
A sequence of three DNA bases, called a_____________, codes for a specific amino acid.
The genetic code is universal, non-overlapping and _______________.
In eukaryotes, much of the nuclear DNA does not code for ____________
There are, for example, non-coding multiple repeats of base sequences between genes. Even within a gene only some sequences, called _________, code for amino acid sequences.
Within the gene, these exons are separated by one or more non-coding sequences, called __________.
A ________ is a section of DNA located at a particular site on a DNA molecule, called its locus.
The base sequence of each gene carries the coded genetic information that determines the ______________ of amino acids during protein synthesis.
The_________code used is the same in all organisms, providing indirect evidence for evolution.
Genetic __________ within a species can be caused by gene mutation, chromosome mutation or random factors associated with meiosis and fertilisation. This genetic diversity is acted upon by natural selection, resulting in species becoming better adapted to their environment.
Variation within a species can be measured using __________ in the base sequence of DNA or in the amino acid sequence of proteins.
Biodiversity within a community can be measured using species richness and an __________of diversity.
Biodiversity within a community can be measured using species ________ and an index of diversity.
