Answer:
C) is the part of the strand that is added first
Explanation:
DNA replication occur by a semiconservative model. During DNA replication the strands of DNA are unbounded by DNA helicase and stabilized by single cell binding proteins.
The primase enzyme build the short primers and DNA polymerase synthesize the new strand of DNA. One restriction for DNA polymerase is that it can only synthesize the DNA strand in 5' to 3' direction. That's why 5' end of DNA is always synthesized first.
The leading strand is synthesized continuously and lagging strand is synthesized in fragments known as okazaki fragments because of DNA polymerase ability to synthesize the strand in only 5' to 3' direction. These fragments are joined by DNA ligase and RNA primers are also replaced by DNA polymerase.
Having to have a prolong cut off with the baby’s oxygen
supply during delivery can cause oxygen deprivation. Oxygen deprivation could
cause the baby to have cyanosis in which the baby will turn bluish and the
heart rate of the baby will increase. As this prolongs, it could lead to loss
of consciousness, seizures, coma, fainting or even worst, brain dead.
Answer:
Iraq is home to diverse ethnic groups including Arabs, Kurds, Assyrians, Turkmen, Shabakis, Yazidis, Armenians, Mandaeans, Circassians, Sabians and Kawliya. Around 99% of the country's 38 million citizens are Muslims, with small minorities of Christians, Yarsans, Yezidis and Mandeans also present.

Question:
Albinism in blue jays is a recessive trait. Over time, the percentage of albino blue jays in a population will remain stable in a population from generation to generation if which conditions are met?
Answer:
- Random matings
- No superposed generations
- No mutations
- No migration
- Infinite population size
- No natural selection
Explanation:
If frequencies stabilize in the population, generation after generation, then it means the population met Hardy-Weinberg equilibrium. Populations in H-W equilibrium will get the same allelic frequencies generation after generation.
Hardy-Weinberg assumption for a population in equilibrium:
• Random matings: Any individual get crossed with any other individual
• No superposed generations: each individual can leave their gametes in the pool only once.
• No mutations: No mutations originate in any new gametes.
• No migration: No incorporation of gametes from other populations
• Infinite population size: the probabilities of randomly taking an A gamete from the pool are p, and the probability of taking a B gamete is q.
• No natural selection: Each individual has equal surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.
Answer:
They have a negative charge since they are represented by a minus sign.
