Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Transcription of the sequence TTAAG produces which sequence?
A
TTAAG
B
UUAAG
C
AAUUC
D
AATTC
Explanation: 

Detailed explanation-1: -Here, A base pairs with the U rather than T as T is not present in the mRNA, T base pairs with A, C base pairs with G and vice versa. Thus, the sequence of mRNA produced from the sequence TTAAG is AAUUC. Therefore, the correct option is C.

Detailed explanation-2: -The given DNA sequence on DNA is: CGATTACAG. A on DNA will pair with U and C will pair with G. The corresponding mRNA sequence will be: GCUAAUGUC. Was this answer helpful?

Detailed explanation-3: -The goal of transcription is to make a RNA copy of a gene’s DNA sequence.

Detailed explanation-4: -Translation of the dna sequence AAGCTGGGA would result in a DNA strand with a base sequence TTCGACCT. Explanation: When the genetic code from one strand is translated into the genetic code of another strand then this process is called as DNA translation.

Detailed explanation-5: -What is the transcription product of the sequence GCTAGCGATGAC? four amino acids.
