Answer:
True
Explanation:
DNA ligases are enzymes required for replication, repair, and recombination of DNA molecules. The DNA ligase repairs the break in the DNA molecule by the formation of a phosphodiester bond.
The bacterial genome consists of a circular DNA molecule, thereby laboratories use these enzymes to create recombinant DNA molecules
Nonsense mutations make stop codons. If the mutation is towards the beginning of a gene, then the protein that gets created will be cut short and not function properly. But if it was towards the end, there is still a chance that the protein will still be able to work.
Answer:
ZBWCYAX
Explanation:
Equation for the intermediates: Z↔W↔Y↔X
1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.
2) If enzyme C is inactive then the organism will not receive Y to grow, thus Y is a by-product of C.
3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.
4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.
Answer:
After an organism's soft tissues decay in sediment, the hard parts — particularly the bones — are left behind. Water seeps into the remains, and minerals dissolved in the water seep into the spaces within the remains, where they form crystals. ... If that mold gets filled with other minerals, it becomes a cast.
Explanation:
TRUE
Pollution can be defined as the introduction of biological matter, particulate and chemicals that are harmful to humans, plants and animals. pollution can also cause damage to natural environment. However, animal digestion can cause natural air pollution by releasing methane which is a greenhouse gas.
