Which of these is the most inclusive component of an organism? the dna, the genes, the proteins, or the chromosomes.
00:11
So we're asking for something here that contains all of the others.
00:15
And the answer to that is the chromosomes.
00:22
So if we look at these structures we've been given, a chromosome is a rod -shaped structure, and within it, it has dna.
00:32
So it has a strand, well, a molecule of dna, which has two strands.
00:45
And this molecule is going to be huge.
00:47
So it could be millions of bases in length.
00:51
And within that molecule of dna, we have a series of genes.
00:55
So a gene is a segment of dna.
01:01
So the dna molecule within this chromosome could have hundreds of these...
