Answer:
Why does dna rely on rna?
Transcription is carried out by the DNA-dependent RNA polymerase that replicates the series of the DNA chain into RNA. To start transcribing the sequence, the RNA polymerase binds to the series of DNA called the promoter and divides the DNA strands. It then copies the sequence series into the messenger RNA copy until it hits the part of DNA named the Terminator, where it halts and detaches from the DNA. As with being DNA-dependent DNA polymerases, RNA polymerase II, this protein that transcribes most of these factors at the human genome, controls as part of the huge protein structure with multiple regulatory and accessory subunits.
Why can’t dna deliver the instructions to the ribosomes directly
Transcription begins at the nucleus, which is the mind of the cell. It contains DNA which include all the messages we want to create proteins. These messages are taken by those ribosomes outside the nucleus. DNA is also valuable to be run in the cell, it wants to be there as a kind of professional material. Then this cell gets another copy of it in the process called transcription.
<span>The correct answer is A) a single amino acid may have more than one codon that translates for it.</span>
<span>This property of the codon is called codon degeneracy and is the redundancy of the genetic code. As a result, there is the multiplicity of three-base-pair codon combinations that specify an amino acid and that increases tolerance to point mutations (synonymous mutations). Usually, the codons encoding one amino acid differ in the second or third position.</span>
Helicase enzyme work to unzip the two strands
<span> Just follow the rock cycle.
(1) Rock is broken down
(2) Regolith is eroded/transported
(3) Regolith is dumped
(4) Layers begin to compact
(5) Sedimentary rock is buried and turned into metamorphic rock
(6) Metamorphic rock melts to magma
(7) Magma resurfaces as igneous rock </span>
The answer is c. Limestone, Hope this helped!
