Alright, so in this question, we are given eight different statements, and we are just classifying them based on whether they are true or false concerning dna.
00:11
So i have true and false laid out on the whiteboard below, and i'm simply just going to use numbers 1 through 8 to represent our statements instead of just writing them all out to save some time and room on the screen down below.
00:24
So first, number one, dna is composed of four different nucleotides, and this is true.
00:32
Dna is composed of adenine, guanine, cytosine, and guan, or excuse me, cytosine, adenine, guan, and thymine.
00:42
Number two, one chromosome contains many protein coding genes, and this is true.
00:50
Chromosomes overall represent a condensed version of all of our dna that makes up our dna in our system, obviously, and one even just dna.
01:04
Sequence contain many protein coding genes.
01:08
So yes, chromosomes contain many protein coding genes.
01:12
Number three, the nitrogenous basis found in dna are known as ac, g, t, and u.
01:18
This is false.
01:20
Due to the fact that u or urasil is not found in dna, that is found in rna.
01:26
Number four, dna is composed of five different nucleotides.
01:30
This is false...
