Simply, transcription is a copy of __________

Biology
1 answer:
WITCHER [35]3 years ago
4 0

Answer:

b. mRNA from DNA

Explanation:

Transcription is the process of synthesis of RNA using a DNA template strand. The process of transcription occurs inside the nucleus in eukaryotes as their DNA is present in the nucleus.

The process includes unwinding of DNA double helix to expose the DNA template strand. The enzyme RNA polymerase binds to the specific start sites on the DNA template strand and starts making its RNA copy.

The newly formed RNA undergoes modification in eukaryotes before serving as a template for protein synthesis. However, in prokaryotes, the process of transcription and translation can occur simultaneously.

Celery stalks that are immersed in fresh water for several hours become stiff. Similar stalks left in a 0.15 M salt solution bec
mixer [17]

Answer:

From this it can be deduced that the fresh water is hypotonic and the salt solution is hypertonic to the cells of the celery stalks.

Explanation:

When submerged in water, the celery stalks become stiff and hard, this shows that water moves within the stalk, thus, water is hypotonic in comparison to the celery stalk. Therefore, water moves from the region of higher concentration to the region of lower concentration.  

When the same celery stalk is administered into the 0.15 M solution it turns soft, which shows that water from the celery stalk moves out. Thus, the salt solution is hypertonic in comparison to the celery stalk. Therefore, freshwater is hypertonic and the solution of salt is hypertonic to the celery stalk cells.

If you have a magnified image that’s 2mm wide and your specimen is 0.02 mm wide, what is the magnification?
DiKsa [7]

Answer:

Magnification = Actual length of image / Actual length of object

Actual length of object = 0.02mm

Actual length of image = 2mm

Magnification = 2mm / 0.02mm

= 100

What does it mean if a population is in Hardy-Weinberg equilibrium? Be specific.
Andrej [43]

Answer:

The Hardy-Weinberg law states that in a sufficiently large population, in which matings occur randomly and that is not subject to mutation, selection or migration, gene and genotypic free frequencies are kept constant from one generation to another, once a state of equilibrium has been reached, which in autosomal loci is reached after one generation.

It is said that a population is in equilibrium when the alleles of the polymorphic systems maintain their frequency in the population throughout the generations.
