Watson and Crick described it well in their published work on DNA and its structure. ... This understanding of the structure of DNA is particularly important because it led to the realisation that if there is an adenine on one side of the pair, then the other base must be thymine.
Answer: the season would change rapidly this could mean longer summers and winters example, for the icy places that need a longer winter would start evaporating to the lack of warmth to keep everything the same temperature these small differences can then develop into more saviour problems such as rapid decrease in fruits in vegetables for the places that will bee getting summers later
Explanation:
Prokaryotic cells are simple, ancient cells without a nucleus. Eukaryotic cells are more complex and have a nucleus.
Answer:
i think it is false. because symbiotic soil microbes do that
Proteins are polymers composed of repeating units of amino acids, linked via peptide bonds (bonds between the amine and carboxyl groups of the adjacent amino acids). All proteins have a primary, secondary and tertiary structure and some, such as haemoglobin, have a quaternary structure.
Primary structure of the proteins are the sequence of amino acids and their order. The "R" regions of the amino acids determine the proteins secondary tertiary and quaternary structures.
In the secondary structure, the protein folds into either an alpha helix or a beta pleated sheet. This occurs due to hydrogen bonding between the "R" group of the amino acids.
The tertiary structure gives the protein its 3D shape. Here it is folded further and more bonds (such as disulphide bonds) also form.
In the quaternary structure, prosthetic groups (e.g. a haem group for haemoglobin) is added. If the protein has more than one protein chains, here the chains join to form the final protein.
