The corresponding sequence in the RNA transcript is 5'-UACGACUG-3' . One of the differences between DNA and RNA is the fact that the RNA contains the base uracil instead of thyamine. The base pairing occurs between A and T, and G and C. DNA undergoes the process of transcription in the nucleus to generate RNA, which then undergoes translation (for mRNA) in the cytoplasm to yield proteins.
Answer:
The correct answer is option B, that is, promoter, operator, gene.
Explanation:
In a prokaryote, just in front of the operator, the promoter is located, and just in front of the structural genes, the operator is located. All these in combination give rise to an operon.
Any gene, which codes for an enzyme or a structural protein is termed as a structural gene, in the lac operon, a structural gene codes for three distinct kinds of enzymes. A short sequence of DNA is situated just in front of the structural gene, which is known as the operator. An operator functions as a switch for transcription, that is, it monitors whether the process of transcription will take place or not.
Just in front of an operator, a sequence of a promoter is present, and for the transcription and translation of all the structural genes, the RNA polymerase needs to combine first with the promoter. In case, if no transcription is to take place, then the operator allows the repressor to bind with it and prevent the attachment of RNA polymerase with the promoter. Hence, the correct sequence of a prokaryotic operon is a promoter, operator, and gene.
Answer:
69.7%
Explanation:
Adenine base pairs with thymine
guanine base pairs with cytosine
you need to get to 100%
30.3-100=69.7%
There will be 30.3% or adenine and thymine and 69.7% or guanine and cytosine.
Answer:
the answer would probably be 75%
Explanation:
If you do a punnet square it will show the results.
Answer:
Thus, the minimum number of photons per second is 77.34
Explanation:
Light intensity, 
= 
Pupil has a diameter, d = 8.5 mm
= 8.5 x 
m
Radius of the eye, r = 4.25 x m
∴ Area of the eye, A = 
= 
= 
Let 
be the minimum number of photons.
Therefore, = x A
= 
x 
= 
W
Thus the minimum number of photons is given by
where E = 
= 
= 
Therefore, 
= 
= 77.34 photons per second
Thus, the minimum number of photons per second is 77.34
