Answer:
The correct answer is nitrogen base
Explanation:
The nucleotide sequence of one codon differ from that of another codon by the presence or absence of specific nitrogen base.The nucleotide sequence of different codons contain different nitrogen bases.
As a result change in genetic code result from the change in the nitrogen bases of the codons present in the genetic code.
In simple words change in single nitrogen base of a codon will change the entire codon.
Both plants and animals have these. It is a eukaryotic cell.
Answer:
<em> e) Ala</em>
Explanation:
Alpha helix is a secondary structure of proteins, it is made of 3.6 aminoacids residues per turn, this structure is possible thanks to local hydrogen bonding between C=O and N-h groups. The result is a cylindrical structure with a hydrogen-bonded backbone and the outside studded with side chains.
Glycin has an -H in its side chain, this makes it a too flexible molecule, therefore it's unusual to find them in alpha-helical structures because their presence could cause the helix to deform. Large R-groups can also affect this stability, phenylalanine has a bulky aromatic side group, this discards it as a stabilizer. Serine has a hydrogen bond donor or acceptor as a side chain, due to the proximity to the main chain it competes with the main chain to form NH and CO bonds. Alanine is the most common amino acid in alpha-helix structures because it has a short and no charged R group (unlike arginine that even when it's short it has a charged R-group), this makes it flexible enough to keep the structure stabilized.
Hope you find this information useful! good luck!
Answer:
ribsosomes: synthesize proteins
Humans cut down forests so that they can build homes, factories, shops etc.
This impacts wildlife because it destroys their home.
