Use the double-stranded DNA molecule below to answer the following questions. The first pair of nucleotides (bolded) contains th
krok68 [10]

Answer:

The correct answer is 2. 5'-AUGUCAGGUACGCCACAU-3'

Explanation:

The template strand for transcription is 3'-TACAGTCCATGCGGTGTA-5 and RNA polymerase will add complementary mRNA sequence against this strand in the opposite direction i.e., 5' to 3' direction.

In RNA, A(adenine) makes complementary base pairing with U(uracil), not with T(thymine) and the rest of the base-pairing is same as in DNA. Therefore the correct mRNA produced from the transcription of this DNA molecule by the help of RNA polymerase is 5'-AUGUCAGGUACGCCACAU-3'.

Then this mRNA sequence will be used by ribosomes to synthesize proteins during the translation process.

Which is more important in the prophase of mitosis, that the chromatid pairs become visible, or the nuclear membrane disappears?
balandron [24]
  that the chromatid pairs become visible
<span>
Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size. </span>

Each month's fertile period is different for every woman, but on average the days between the 10th and 17th day of the cycle are the most fertile ones. More specifically, this period refers to days 12 to 16 before the beginning of the next period. This timeframe refers to the ovulation, the process that includes the release of an egg from an ovary.
