Answer:
<h2>A site for the exit of the diphosphates removed from the nucleotide triphosphates.</h2>
Explanation:
Transcription occurs in three steps, i) initiation, ii) elongation, and iii) termination.
Elongation: during elongation , the RNA polymerase add new nucleotides in the growing chain of RNA molecule until it encounter terminator factor, or until it terminate transcription. RNA polymerase has three prominent channels, i) channel for entry of DNA template strand, ii) channel for exit of DNA strand and iii) channel for exit of newly synthesized RNA molecule. There are lots of other enzymes which helps in transcription.
This can cause mutations, these mutations can be helpful,harmless or they can be harmful.
Pangea began to separate.
Answer:b. Amino acid sequence, hydrogen bonding between backbone groups, the overall shape of a single polypeptide, and combinations of tertiary structures.
Explanation: Primary structure is the amino acid sequence in the polypeptide chain. When the sequence is altered due to mutation it can lead to formation of entirely new amino acid sequence.
Secondary structure could be the helical structure or the Beta pleated sheet. It is form from the interaction of atom that are backbones.It is the hydrogen bond between amino Hydrogen and carboxyl oxygen atom in the backbones
Tertiary structure- Overall structure of polypeptide. It result from interaction of the R groups amino acids. It gives the shape of the polypeptide.
Quantenary- Are protein made up of multiple polypeptide chain. This chain are also called subunit. It is the combination of all tertiary structures given rise to a functional protein.
Answer:
Prokaryotic cells include archaea and bacteria. They do not have membrane bound nucleus as well as most of the organelles
