Answer:DNA is antiparallel.
Explanation: DNA is a double stranded helix in which the two strands are antiparallel. Being antiparallel means that as one strand runs from 5'->3' direction, the other strand runs from 3'->5' direction. During DNA each of the two strands serves as a template for a new complementary strand. The synthesis of a new DNA strand is always in the 5'->3' direction, therefore one strand is synthesized continuously in the direction of the replication fork while the other strand is synthesized discontinuously in the direction opposite to the replication fork in short fragments called the Okazaki fragments. The strand that is synthesized continuously is called the leading strand while the strand that is synthesized discontinuously in Okazaki fragments is called the lagging strand.
Answer:
false
Explanation:
This cannot be true because other planets, Earth included orbit the sun witch would have to emit its own gravity
Answer:
More than two complete sets of the chromosomes (polyploidy).
Explanation:
Assembly of spindle microtubules assist the chromosomes to arrange in the equator of the cell during metaphase. This is followed by the splitting of centromere and segregation of sister chromatids towards the opposite poles of the cell to ensure equal distribution of chromosomes among the daughter cells.
Any drug that prevents the assembly of the spindle apparatus would not allow the alignment of the chromosomes in the cell's equator. This would prevent the anaphasic segregation of daughter chromosomes to the opposite poles.
Some of the resulting daughter cells are most likely to have more than two sets of chromosomes.
Answer:
Number 3
Explanation:
Dominant: 20, Recessive: 20
An allele is the alternative of a gene. On his case, these beans represent the alleles for a simple Mendelian trait, where red is dominant (R) and white is recessive (r).
As states earlier there are 20 red beans (20 dominant alleles) and 20 white beans (20 recessive beans) and each beach represent an allele.
Answer:
If cellular respiration and photosynthesis stops performing their role in carbon cycle all the plants and animals will end up dying. This is because they are dependent on the carbon cycle for survival.
