Answer:

B.) Skeletal muscles

Explanation:

Skeletal muscles are also known as striped or striated or voluntary muscles. These muscles are attached to the skeleton. These muscles are present in bundles. Each muscle fibre is an elongated cell having large number of myofibrils in its cytoplasm. Each myofibril has dark and light bands on it. The dark bands are A-bands or aniso-tropic bands and the light bands are I-bands or isotropic bands.

You decide to repeat the Meselson-Stahl experiment, except this time you plan to grow the cells on light 14N medium for many gen
Effectus [21]

Answer:

One band of light density and one band of heavy density.

Explanation:

According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.

Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).
