Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Josh is assigned a project in class to make a strand of m-RNA from DNA.The DNA code that he has been assigned is CGG TCG AGT GAT. What would be the correct code for Josh to use in his transcription?
A
GCC AGC TCA CTA
B
GCC UGC TCA CTU
C
GCC AGG TGA CTA
D
GCC AGC UCA CUA
Explanation: 

Detailed explanation-1: -Expert-Verified Answer. GCC AGC UCA CUA would be the correct transcription code.

Detailed explanation-2: -The “antisense” strand of DNA is complementary to the “sense” strand and is the actual template for mRNA synthesis.

Detailed explanation-3: -In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.

Detailed explanation-4: -RNA polymerase synthesizes an RNA transcript complementary to the DNA template strand in the 5’ to 3’ direction. It moves forward along the template strand in the 3’ to 5’ direction, opening the DNA double helix as it goes.

Detailed explanation-5: -During the process of transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.
