Discuss ONE type of control that occurs at the chromosomal/DNA level and ONE that occurs at the mRNA level. Compare these two co
blagie [28]

Answer:

One type of control that occurs at the DNA level is the regulator genes. The regulator genes synthesize a repressor molecule that binds to the operator and stops transcription of the structural genes. Whenever there is enough amount of structural genes made, a repressor molecule will bind to the operator region and stop further transcription.

One type of control that occurs at the RNA level is RNA splicing. By this method, different proteins can be made by a single RNA transcript.

andreyandreev [35.5K]

Answer:

The answers are:

  1. Type 2 (fast twitch) muscle fibers - type A:    b. muscle fibers that help with a long sprint or carry a heavy object a short distance
  2. muscular strength:    d. the muscle's capacity to exert force against resistance
  3. Type 1 (slow twitch) muscle fibers:   a. muscle fibers responsible for endurance
  4. Muscle endurance:    c. refers to the ability to perform a specific muscular action for a prolonged amount of time.
  5. Type 2 (fast twitch) muscle fibers - type B:     e. muscle fibers used in short explosive movements such as jumping or lifting a very heavy weight one or two times.

Explanation:

Types of Skeletal Muscles:

Skeletal muscle are divided into two types:

  1. Slow Twitch (Type 1)
  2. Fast Twitch (Type 2)
  • Slow twitch muscles are the first ones to contract at times of exercise of strenuous physical activity. A compared to fast twitch muscle fibers, they contract slowly but can sustain contraction for a long time.
  • Fast twitch muscle fibers are divided into two subtypes: Type 2A and Type 2B.
  • Type 2A muscle fibers produce a high amount of force but they fatigue rapidly.
  • Type 2B muscle fibers, fire last, produce the most amount of force but wear out very rapidly.

Muscle Characteristics:

  • Muscle endurance is the muscle's ability to contract with force against a resistance for a prolonged time period.
  • Muscle strength is a measure of the amount of force a muscle can produce against resistance.
