Answer:
24 chromosomes
Explanation:
The Human Genome Is Composed of 24 Different Types of DNA Molecules. Human DNA is packaged into physically separate units called chromosomes.
The base pairing rules<span> for </span>DNA<span> are governed by the complementary </span>base pairs<span>: adenine (A) with thymine (T) in an A-T </span>pairing<span> and cytosine (C) with guanine (G) in a C-G </span>pairing<span>. Conversely, thymine only binds with adenine in a T-A </span>pairing<span> and guanine only binds with cytosine in a G-C </span>pairing<span>.</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
1. Naked Seeds, Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination.
