Answer:

Invertebrates are the organisms in which backbone or vertebral column is absent.

The three macroinvertebrate categories are annelids, mollusks and arthropods.

Annelids are the organisms having segmented body. They are found in moist places. Examples are leeches and earth worms.

Mollusks are the organisms which are enclosed in a calcium carbonate shell. Examples are snails and slugs.

arthropods are the invertebrates which have segmented body and jointed appendages. Examples are insects and crustaceans etc.

Leokris [45]

Answer:

Part A: Thr-Leu-Val

Part B: ACC-UUG-GUU

Explanation:

When you transcribe a DNA sequence to mRNA, you need to remember that in RNA there is no Thymine (T), instead it has Uracil (U). So the base pairings would be like this compared to DNA base pairing:

DNA                RNA

A-T                  A-U

T-A                  T-A

C-G                 G-C

G-C                 C-G

Given the sequence the transcription will be as follows:

DNA :   TGG - AAC - CAA  

mRNA: ACC - UUG - GUU

Next, to translate it into amino acids, you will use the chart. Now amino acids pair in codons (3 base pairs at a time).  Let's take the first codon in your sequence:

ACC

1st  2nd   3rd

 A     C       C

Using the column on the left, find the row that matches it, so in this case A.

At the very top, there is another row of letters, looking at the row of A only, look for the column of the second base which is C.

Lastly, look at the right most column and find the letter that matches the third base within the box where A and C intersect. In this case, C is your third base.

The amino acid where all three intersect is your first amino acid which is Thr.

Just do this for the next codons and you will come up with the answer.
