Answer: Mitochondria are shaped to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae.
Because of the antibodies produced by the mother, inherent immunity..
Answer:
Translation
Explanation:
During translation, mRNA arrives at a ribosome. Within the ribosome, the mRNA temporarily binds to tRNA's via complementation. The tRNA's are responsible for gathering the relevant amino acids and creating a new protein.
Answer:
RNA-dependent RNA polymerase.
Explanation:
DNA polymerase I is present in E.coli that are responsible for the prokaryotic DNA replication. The DNA polymerase I was discovered by Arthur Kornberg. This enzyme is coded by the gene polA.
DNA polymerase I has the activites of DNA-dependent RNA polymerase, DNA-dependent DNA polymerase and RNA-dependent DNA polymerase. The RNA-dependent RNA polymerase is generally present in the reverse transcriptase in case of viruses only. RNA-dependent RNA polymerase catalytic site is not present in DNA polymerase I.
Thus, the correct answer is option (1).
Macromolecule polymers are assembled by the connecting of repeating monomers. For every subunit supplementary to a macromolecule one water molecule is detached. Macromolecule polymers are broken down by breaking bonds among subunits. This procedure is named hydrolysis and is the opposite of dehydration in which they are broken down over hydrolysis or the use of water to break down polymers.
