Students are modeling mRNA during the process of protein synthesis. Which answer choice correctly describes the model of the mRN
ELEN [110]

The mRNA strand is complementary to the DNA template strand; however, uracil instead of adenine is paired with thymine best describes the model of the mRNA strand being transcribed.

<h3>What is mRNA?</h3>

This is referred to as messenger RNA and is a type of single-stranded RNA which is involved in protein synthesis. It carries the genetic information needed to make proteins and is complementary to the DNA template strand.

It however has a different base pair to DNA such that uracil instead of adenine is paired with thymine.

This base pair difference is therefore described as the most appropriate choice in the description of the mRNA strand.

How igneous and sedimentary rocks turn to metamorphic rocks?
Darina [25.2K]

Answer:

Heat, pressure and chemistry compounds around the rocks.

Explanation:

Metamorphic rock is formed by pre-existent rocks (igneous and sedimentary, sometimes from another metamorphic rock), those rocks were modified by the effect of heat (high temperature), pressure (under the terrestrial surface) and chemistry compounds around the rocks. The physical and mineralogical composition becomes different than the original form.

This process is called metamorphism.

Based on her pre-pregnancy weight, if she is carrying a single baby, how much weight should sadie gain during her pregnancy?
fomenos
The number of weight gained in pregnancy should be different based on the BMI. Assuming Sadie BMI is 25-29.9kg/m2 then the normal weight gain for single pregnancy would be 15 to 25lbs.
Higher BMI will cause the normal weight gain become lower. For BMI >30kg/m2 normal weight gain would be 11-20lbs
