Hope it helps!
Answer:
During the long voyage, Darwin made many observations that helped him form his theory of evolution. For example: He visited tropical rainforests and other new habitats where he saw many plants and animals he had never seen before (see Figure below). This impressed him with the great diversity of life
Explanation:
: )
It is because Prokaryotic cells has a unicellular structure compared to Eukaryotic cells which has a Multicellular structure.
Answer:
C. that there may be more than one way to interpret data
Explanation:
When determining if an explanation is correct you must always remember that there may be more than one way to interpret data. Depending on the context that the explanation is being used in or who is reading it, the explanation may be interpreted in two completely different manners which may be far off from the original intended explanation. This can therefore completely nullify or maybe even expand the original determination.
Answer:
The correct order would be:
RNA polymerase unzips the DNA molecule.
↓
Free RNA nucleotides pair with the complementary DNA nucleotides on one strand of DNA.
↓
The mRNA molecule breaks away as the DNA strands rejoin.
Transcription is the process by which nucleotide sequence of the DNA is decoded in the from the nucleotide sequence of RNA.
It is the first step of gene expression which is catalyzed by DNA dependent-RNA polymerase.
The process of transcription can be divided into three steps:
1. Initiation: RNA polymerase binds to the promoter region of the DNA and forms the transcription bubble with the help of transcription factors.
2. Elongation: RNA polymerase adds RNA nucleotides complementary to the nucleotide sequence of the template strand of DNA.
3. Termination: Once the RNA polymerase reaches the terminator region of the DNA, nascent RNA chain and RNA polymerase fall off with the help of termination factors. The transcription bubble is sealed back by rejoining of the DNA strands.
