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.
Answer:
D. Transport of oxygen through a placenta to a fetus.
Explanation:
Zygotes are fertilized egg cell, zygotes aren't produced in the ovaries but ovums or egg cells are produced in the ovaries. So option A is false.
Fertilization is internal not external in human. Option B is wrong.
Production of milk happens in the mammary gland (the breast) not in the reproductive system. Option C is false.
Transport of oxygen through a placenta to a fetus. The placenta is a vascular organ which is implanted in the wall of the uterus (a part of the female reproductive system) and links to the foetus through the umbilical cord.
Answer:
The answer is motor end plate.
Explanation:
<em>The region of the sarcolemma across from the axon terminal at the neuromuscular junction is the motor end plate.</em>
