Answer:
B. DNA unzips before step 1.
Explanation:
This question is describing the process of gene expression, which is made up of two major stages namely; transcription and translation. Transcription is the process by which mRNA is synthesized from a DNA template while translation is the process where protein (amino acid sequence) is produced using the mRNA transcript.
This stages of gene expression has been summarized in the steps listed by Shura. However, prior to the formation of an mRNA molecule in step 1, the double stranded DNA has to unwind i.e. separate into single strands as initiated by the enzyme RNA polymerase. Therefore, the list should read as follows:
- DNA unzips
- A strand of RNA is made.
- RNA leaves the nucleus.
- RNA moves to the ribosome.
- A protein is made.
Answer: Option A
Explanation:
Mendel used many the same pea plants for the description of many characters independently in those pea plants only.
The Principal of Independent Assortment states how different genes express themselves independently when reproductive cells develop.
This was first observed by Mendel by his experiments. Every character of the pea plants that he used appeared independently.None of the two characters got mixed with one another.
Hence, the correct answer is option A
Answer:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. ... DNA fragments are negatively charged, so they move towards the positive electrode. Because all DNA fragments have the same amount of charge per mass, small fragments move through the gel faster than large ones.
