Describe how DNA replication relates to transmission and conservation of genetic information.

Biology

Jet001 [13]3 years ago
3 0
DNA replication follows the base pairing rule (A with T and G with C). This ensures identical replication of the genetic information; hence it's conservation. Each daughter DNA double helix contains one old strand of DNA and one newly-synthesized strand of DNA. This is known as the semi-conservative mechanism.
DNA replication also occurs during mitosis which produces haploid gametes. Each parent contributes half of the genetic information during fertilization of two gametes, thus regenerating the diploid number. Genes from both parents are transmitted to the offspring.

How can a population grow?
Vlad1618 [11]
Under ideal conditions, populations can grow exponentially. The growth rate increases as the population gets larger. Most populations do not live under ideal conditions and grow logistically instead. Density-dependent factors slow population growth as population size nears the carrying capacity.

What are the two different results of a lack of calcium and a lack of atp?
liq [111]
<span>There are numerous proteins in muscle. The main two are thin actin filaments and thick myosin filaments. Thin filaments form a scaffold that thick filaments crawl up. There are many regulatory proteins such as troponin I, troponin C, and tropomyosin. There are also proteins that stabilize the cells and anchor the filaments to other cellular structures. A prime example of this is dystrophin. This protein is thought to stabilize the cell membrane during contraction and prevent it from breaking. Those who lack completely lack dystrophin have a disorder known as Duchene muscular dystrophy. This disease is characterized by muscle wasting begininng in at a young age and usually results in death by the mid 20s. The sarcomere is the repeating unit of skeletal muscle. 

Muscle cells contract by interactions of myosin heads on thick filament with actin monomers on thin filament. The myosin heads bind tightly to actin monomers until ATP binds to the myosin. This causes the release of the myosin head, which subsequently swings foward and associates with an actin monomer further up the thin filament. Hydrolysis and of ATP and the release of ADP and a phosphate allows the mysosin head to pull the thick filament up the thin filament. There are roughly 500 myosin heads on each thick filament and when they repeatedly move up the thin filament, the muscle contracts. There are many regulatory proteins of this contraction. For example, troponin I, troponin C, and tropomyosin form a regulatory switch that blocks myosin heads from binding to actin monomers until a nerve impulse stimulates an influx of calcium. This causes the switch to allow the myosin to bind to the actin and allows the muscle to contract. </span><span>
