Explain the relationship between the E.R. and the Cell Membrane

Biology
1 answer:
lesya [120]4 years ago
7 0
Ribosomes are attached to the membrane of the ER, making it “rough.” The RER is also attached to the nuclear envelope that surrounds the nucleus. This direct connection between the perinuclear space and the lumen of the ER allows for the movement of molecules through both membranes.

Part A: A scientist examines a fruit fly gene involved with the regulation of body development. A section of the DNA sequence fo
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.
