Hello there.
<span>What amino acid is specified by the codon of GCG, and will there be a change if the codon is changed to GCC?
</span><span>A) The amino acid ala is not changed.</span>
False. His telescope was a refractor.
Answer:
A. UUA AAG GCU UAC CCU
Explanation:
Transcription is the first process of Gene expression, which involves the synthesizing of a mRNA molecule from a DNA strand. This process (transcription) which is carried out or catalyzed by an enzyme called RNA polymerase, uses the complementary base pairing rule to synthesize nucleotides.
The complementary base pairing rule as proposed by Chargaff states that Adenine base (A) should bond with Thymine base (T). Likewise for Guanine (G) and Cytosine (C). Hence, in a DNA strand with sequence: AAT TTC CGA ATG GGA, the following RNA will result:
UUA AAG GCU UAC CCU.
Note that, Uracil base replaced Thymine base in the mRNA molecule.
Since; A-U and G-C
AAT TTC CGA ATG GGA ---------- DNA
UUA AAG GCU UAC CCU --------- RNA
Is this Biology? I learned this in Chemistry!
Answer: A - non-polar Covalent Bond
The hydrogen and oxgen are attracted to each other.
The 'H+' being slightly polar, and the 'O2-' slightly opposite.
