Transcription is the process by which RNA (nucleic acid that is responsible for transferring genetic information from DNA ) is synthesized from the genetic information contained in the coding regions of DNA. Therefore, a copy of complementary RNA and antiparallel to the DNA sequence that was transcribed is obtained. Normally organism synthesize RNA by a reaction catalyzed by RNA polymerases (they are enzymes that are involved in the process of DNA replication).
Transcription occurs in three steps: initiation, elongation and termination.
Initiation: Is the beginning of transcription. It occurs when the RNA polymerase enzyme binds to a region of a gene called a promoter. This tells the DNA to unwind so that enzyme can 'read' the bases in one of the strands of DNA. The enzyme is now ready to create a strand of mRNA (it is a single stranded RNA molecule, complementary to one of the DNA strands of a gene) with a complementary base of bases.
Elongation: Is the addition of nucleotides to the mRNA strand. The RNA polymerase reads the unwound strand of DNA and builds the mRNA molecule, using complementary base pairs. THere is a brief moment during this process when the new RNA molecule is bound to the unwound DNA. During this process, an adenine in the DNA binds to an uracil in the RNA.
Termination: Is the term of transcription and occurs when RNA polymerase crosses a termination sequence in the gene. The mRNA strand is complete and separated from the DNA.
I think the answer to this question is True.
We can conclude from this that bacterial infections are growing immune to the antibiotics
Answer: soft seeds
Explanation:
Tiny, soft seeds that are easy to crush are preferred by the medium ground finch to feed. During droughts, however, they often consume the larger seeds on the island when small seeds are not as available.
If a heterozygous male with the genotype Ww is mated with a homozygous recessive female with the genotype ww, then the probability of heterozygous offspring is 0.5 or 50%. The offspring are Ww, Ww, ww, and ww.
<h3>What is Genotype?</h3>
A genotype may be defined as the ultimate combination of the alleles of those genes which are selected for specific studies.
If a heterozygous male with the genotype Ww is mated with a homozygous dominant female with the genotype WW, then the probability of heterozygous offspring is 0.5 or 50%. The offspring are WW, WW, Ww, and Ww.
Therefore, it is well described above.
