Answer:
Organic compounds→ nucleotides→ RNA→ universal code.
Organic compounds are the compounds made by living organisms with at least one molecule of carbon linked to different elements like hydrogen, oxygen, or nitrogen.for example: nucleotides.
A nucleotide is the monomer units of nucleic acids- DNA and RNA. Each nucleotide is made up of organic compounds- sugar, a phosphate molecule and nitrogenous bases (adenine, guanine, cytosine, thymine and uracil).
The arrangement of nitrogenous bases in DNA decides the fate of proteins as the sequence of these bases acts as code arranged in the triplet called "codons" which code for specific amino acids.
Thus, Organic compounds→ nucleotides→ RNA→ universal code is the correct answer.
Answer: B
Explanation:
The question wants to know what the expression is directly dependent on.
The sequence of genetic expression goes like this:
DNA -> RNA -> protein
If we want to know the root cause of expression, we must look at the DNA, not the RNA or protein, because DNA determines the RNA and protein expression.
The Shape of subunits in DNA -> Sequence of bases coded for by the ribosome with RNA -> Arrangement of amino acids in the protein synthesized.
Why not C: Number of chromosomes present isn't a factor, because most humans, barring those with a genetic disorder, have 23.
Answer:
The correct answer is B. DNA helicase first unwinds the double helix around the +1 site.
Explanation:
The helicase is an enzyme that specifically breaks the hydrogen bonds of the bases in the transcription process. As E. Coli is a prokaryote, then, the transcription only occurs in one point of the circular DNA. The promoter region indicates where the DNA polymerase has to start replicating and the Topoisomerase unwinds the parts of the DNA that are being excessively twisted because of the separation of the two strands.
