Answer:
D. I, IV, VI, and VII
Explanation:
DNA polymerase III has both 5' to 3' polymerization activity and 3' to 5' exonuclease activity (the proofreading). DNA pol III requires divalent magnesium ions for its polymerization and proofreading activities. Here, the magnesium ions serve as cofactor.
DNA polymerase III cannot start the process of synthesis of new DNA strand de novo and uses an RNA primer synthesized by primase enzyme. The polymerization activity of DNA polymerase III elongates the RNA primer in 5' to 3' direction. The primers are removed by 5' to 3' exonuclease activity of DNA polymerase I.
During polymerization, the DNA polymerase III uses existing DNA strand as a template. The four dNTPs namely deoxyadenosine triphosphate (dATP), deoxycytidine triphosphate (dCTP), deoxyguanosine triphosphate (dGTP) and deoxythymidine triphosphate (dTTP) are added to the RNA primer according to the sequence of DNA template.
Answer:
Ha, It learned where NOT to land. That's for sure. But the answer is Operant Conditioning.
Explanation:
I believe it's fungi.
Explanation:
- Fungi and plants have similar structures. Plants and fungi live in the same kinds of habitats, such as growing in soil.
-Fungi are not capable of photosynthesis:
-Fungi can't move around so they make spores that are like seeds
Answer:
d) a polypeptide missing an amino acid.
Explanation:
Deletion is a type of mutation when one or more codons from the reading frame are removed. This results in the production of a relatively shorter mRNA that lacks one or more codons otherwise present in the non-mutated mRNA. When there is a deletion of a single codon in the gene for cystic fibrosis, the resultant shorter mRNA codes for a polypeptide chain that does not carry one amino acid. For example, deletion of one codon results in deletion of a Phe residue present at position 508 in CFTR. The mutated transmembrane protein CFTR folds in an improper way.
Answer:
I KNOW THIS
In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes.
