A key part of the Watson-Crick model came when Watson realized
that adenine could form hydrogen bonds with thymine and guanine
could form hydrogen bonds with cytosine. This explains why A=T
and G C in Chargaff's rules. Also, these two hydrogen-bonded
nucleotide pairs had the exact same width, so they could form the
rungs of the DNA ladder.
The fact that these pairs could match up only in this way meant that
the sequence of bases in one strand could determine the sequence
of bases in a second strand created from the first. The second strand
is said to be complementary to the first strand. Individual bases are
paired so that the identity of any base determines the identity of the
base paired with it; that is, the complementary base.
This table lists the base abbreviations for bases in a sample of single-
stranded DNA. Fill in the second column with the base abbreviations
that are complementary to the given bases.

A usually pairs up with TC usually pairs up with GThese are bases of amino acids called nucleotides sequences. And this helps in the bond of several base pairs to their nucleotide sequence.What is the Watson-Crick model?

In “A Structure of Deoxyribose Nucleic Acid,” Watson and Crick defined DNA as a double helix that contained long, helical strands wound together. In their model, every DNA strand contained personal devices referred to as bases, and the bases alongside one DNA strand matched the bases alongside the opposite DNA strand.

Name three reasons why the atmosphere is important to life on earth and explain your reasoning.

Answers

The atmosphere ensures that all living things can carry out daily processes that are vital to survival, such as breathing. Photosynthesis, for example, could not be possible without an atmosphere, because all of the gasses in our atmosphere stay there due to Earth's gravity.

The atmosphere is vital because it plays a role in the water cycle as well, allowing rain to keep falling and giving life-giving water to organisms that need it.

Life would not be possible without an atmosphere on this planet, along with other vital things, like gravity, sunlight, and water.

Answer: B

(An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids. For example, water is composed of hydrogen and oxygen atoms that have combined to form water molecules.)
