Answer:

He should look out for tiny leaf-like structures which mosses possess but algae does not .

Explanation:

In general, moss looks fibrous, feathered or latticed when viewed up close. Carpets of moss are springy to the touch. When germinating, moss puts up thin stems sometimes with leaves on top and reproductive spores. Algae have no threadlike structures or leaves. Instead, algae spread as a clump of living cells. Because algae usually grow in wet environments, they look like a slimy, wet mass, often green in color. Both moss and algae may appear green or brown depending on species and the dryness of the conditions.

KiRa [710]

A particular triplet of bases in the template strand of DNA is 5' agt 3'. the corresponding codon for the mRNA transcribed is<u> 3' UCA 5'</u>

<u></u>

It serves as a link between DNA's genetic code and proteins' amino acid sequences.

The codons in the messenger RNA (mRNA) are complementary to the nucleotide sequence on the DNA template strand.

Then it controls the synthesis of amino acids with the aid of tRNA and ribosomes.

Its name, messenger RNA, refers to the fact that it carries genetic information. The single strands of adenine, cytosine, guanine, and uracil that make up the mRNA molecule are held together by a sugar phosphate backbone.

Two codons: His, Lys, Phe, Tyr, Asn, Asp, Cys, Gln, Glu, Codons Ile, STOP, and three ("nonsense"). Ala, Gly, Pro, Thr, and Val are the four codons. None of the five codons.
