Answer:
Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed.
It help conserve energy so that in summer they can stay healthy. Also alows them to eat a buch of food and it not be so much
Oxygen and carbon dioxide move across a cell membrane due to diffusion. Diffusion is a passive process as it requires no energy to move particles down the concentration gradient.
Answer:
From the translation of the mRNA molecule 5’ AUG AGU CCU CUU UGA 3’ results the amino acid sequence Met-Ser-Pro-Stop, that is, Methionine-Serine-Proline and the last triplet being a stop codon.
Explanation:
Messenger RNA (mRNA) molecule is in charge of conducting the encoded genetic information to produce the protein synthesis, organized in a sequence of nucleotides called the genetic code. The arrangement of the nucleotides is in triplets of bases or codons, which encode the synthesis of an amino acid (translation), determine the beginning of the synthesis and also establish the stop.
In the given sequence, 5’-AUG-AGU-CCU-CUU-UGA-3’ results the amino acid sequence Met-Ser-Pro-Stop:
- <em>5'-AUG</em><em> Methionine (Met), being at the same time an initiating codon.</em>
- <em>AGU</em><em> Serine (Ser).</em>
- <em>CCU</em><em> Proline (Pro).</em>
- <em>UGA-3'</em><em> is a stop codon.</em>
<u>Stop codons do not code for amino acids, but their presence in a codon sequence marks the completion of peptide or protein synthesis</u>.
