Answer:
DNA contains the instructions to help the cell survive. They help the cell produce protein in the stages of protein synthesis.
Answer:
The Cell Cycle is a 4-stage process consisting of Gap 1 (G1), Synthesis, Gap 2 (G2) and Mitosis.
Explanation:
Answer: Van der Waals forces
Explanation:
Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.
The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.
Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.
Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.
Answer:
thanks to the genetic code, this allows cells to decode an mRNA in an amino acid chain
Transfer RNAs, or tRNAs, connect the mRNA codons with the amino acids for which they encode. One end of each tRNA has a three nucleotide sequence called anticodon, which can be attached to a specific codon of the messenger RNA. The other end of tRNA carries the amino acid that specifies the codon that is present in the messenger RNA
