A. T-A-C-G-A-T
A and T pair together, and G and C pair together. There are no U’s because U’s are in RNA, not DNA.
Answer:
A. Scientists discovered chromosomes and DNA.
Explanation:
Mendel's ideas were based on patterns of inheritance in plants. Although he identified these patterns, at the time, we did not know what the hereditary material was. This means Mendel couldn't uncover the mechanism of why he was seeing the patterns he was.
When scientists discovered chromosomes and DNA, they were able to see how Mendel's observations made sense in the context of DNA and chromosomes.
At about day 14 of the
menstrual cycle, a mature ovum is released in a fallopian tube. This process is
known as:
<span>During day 14, ovulation occurs but it can also happen
earlier or later than that. Ovulation happens when an egg is released from your
ovaries and sometimes two eggs are released and not just one.</span>
Answer:
c. one helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction.
Explanation:
A DNA molecule has <em>two strands of nucleotides with a sugar phosphate backbone each, but orientated on the opposite direction </em>allowing for the base pairs to complement one another, making it a more stable structure. <em>When two biopolymers run parallel to each other but with opposite directionality (alignment) we have an antiparallel arrangement.</em>
