The electrons surrounding an atom are located in regions around the nucleus called “energy levels”. An energy level represents the 3-dimensional space surrounding the nucleus where electrons are most likely to be. The first energy level is closest to the nucleus.

Answer:  Located in regions around the nucleus.

Explanation: Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. As you go farther from the nucleus, electrons at higher energy levels have more energy. The electron energy levels are an atom located in regions around the nucleus. An energy level represents the 3-dimensional space surrounding the nucleus where electrons are most likely to be. The first energy level is closest to the nucleus. The second energy level is a little farther away than the first.

Which of the following macromolecules enter the nucleus of a eukaryotic cell through pores in the nuclear membrane? a. rRNAb. ri
Lina20 [59]

Answer:option C= mRNA

Explanation:

MACROMOLECULES are large molecules, such as protein, commonly created by the polymerization of smaller sub-units called monomers.

The NUCLEAR PORE is a protein-lined channel in the nuclear envelope. The NUCLEAR PORE regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.

mRNA is synthesized by DNA during a process known as the TRANSCRIPTION. After the synthesis, the new molecule moves from the nucleus to the cytoplasm. It passes through the nuclear membrane through a NUCLEAR PORE. Then, it will later join with a ribosome, which is just coming together from its two sub-units, one large and one small.

Which organelle contains DNA and controls the activity in the cell?<br> ОВ<br> Ос<br> OD<br> ОЕ
IrinaK [193]

Nucleus can be defined as a large organelle found in the Eukaryotic cells and it is also  know as the cell's command center,thus it controls the activity of the cells

Explanation:

  • The answer to the above question is (c )nucleus. During the cell cycle the nucleus of the cell mediates the replication of the of the DNA and controls the gene expression.
  • The nucleus contains a structure which is known as nucleolus and which is made up of protein and ribonucleic acid(RNA)

If instead of ACT, the first DNA triplet was ACG, which amino acid would be coded for?
BigorU [14]
<span>The answer is cysteine. This is a half essential proteinogenic amino acid with the formulation of HO₂CCHCH₂SH. It is prearranged by the codons UGU and UGC. The thiol side chain in cysteine frequently partakes in enzymatic responses, as a nucleophile.</span>
