We would expect that a 15-nucleotide sequence that includes a stop codon at the end (as part of the 15-nucleotide sequence) will
slega [8]

Answer: Four amino acids.

Explanation:

RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are polymers made up of long chains of nucleotides. Thus, a nucleotide is the basic building block of nucleic acids and consists of a sugar molecule (ribose in RNA or deoxyribose in DNA) linked to a phosphate group and a nitrogenous base. <u>The nitrogenous bases can be Adenine (A), Thymine (T), Cytosine (C), Guanine (G) or Uracil (U) replacing T in RNA</u>. DNA is the molecule that stores the genetic information to synthesize polypeptides or proteins (set of amino acids). When proteins need to be created, DNA is transcribed into RNA and this RNA is translated in ribosomes to create polypeptides.

Complementarity is the ability to combine with their complement. A and T (or U) are complementary, while C and G are complementary to each other. Complementarity is the principle of replication and transcription, because it is a propery of both DNA and RNA sequences. Their the nucleotide bases at each position of the sequences are complementary, allowing cells to copy information.

Nucleotides in RNA are grouped into codons, which consist of groups of 3 nucleotides where each codon codes for an amino acid. Therefore, <u>the sequence of bases in nucleic acids determines which protein will be synthesized</u>. Protein synthesis begins with a start codon (AUG, which codes for the amino acid methionine) and ends with a stop codon (UGA, UAG and UAA). So, if there are 15 nucleotides, there are 15 bases. Since they are grouped in groups of 3, we will have a polypeptide of 4 amino acids.

<u>3 nucleotides form a codon, so 12 nucleotides form 4 codons giving 4 amino acids. The last codon, is formed by the last 3 nucleotides and form the stop codon that stop protein synthesis</u>.

Thorns and small hairs on plant stems and leaves help to
Mkey [24]

The correct answer is - physically dettering herbivory, protection from frost, and minimizing evaporation.

The plants have developed multiple traits that help them in multiple different circumstances, and some of those traits are the thorns and the hairs on their steams and leaves.

The thorns primarily serve for protection of the plant. They are very sharp and give a painful sting (occasionally poisonous one), so they are a physical protection from the herbivores that would try to eat parts of the plants.

The hairs have multiple functions. They are like a coat that helps the plant to not be affected by frost, help to stop the evaporation, and also partially manage to stop most of the insects that feed on plants.
