Which type of mutation stops the translation of the mRNA?

Biology
1 answer:
Gre4nikov [31]3 years ago
6 0

If a substitution changes the amino acid to a “stop,” it's called a NONSENSE mutation. frameshift, missense, silent or nonsense (hint: deletion or insertion will always be frameshift). Sickel cell anemia is the result of a type of mutation in the gene that codes for part of the hemoglobin molecule.

Please help!! I WILL GIVE BRAINLIEST !! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line t
Naddik [55]

Answer:

R = 16mm/y  

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t

To calculate it in millimeters per year we need to convert it:

<em>1 km = 1000 m </em>

<em>1 m = 100 cm </em>

<em>1cm = 10mm</em>

<em>1 km = 1,000,000 mm   </em>

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y

What is the pH of an aqueous solution with the hydronium ion concentration
Anni [7]

Answer:

pH = 13.70

Explanation:

pH is a value used in chemistry to determine nature of solutions, quality of several chemicals, etc.

pH is defined as -log [H₃O⁺]

A solution with molar concentration of hydronium ion, H₃O⁺. of 2x10⁻¹⁴M, has as pH:

pH = -log [2x10⁻¹⁴M]

pH = 13.70

1. Why does the Elodea cell have chloroplasts but the onion cell does not, even though both are plant cells? Please answer quick
Oksanka [162]
Chloroplasts contain chlorophyll which is what makes plants green. Onions are not green because they do not contain chloroplasts. The reason they do not have chloroplasts is because in the chloroplast, photosynthesis takes place. A key player in the process of photosynthesis is the sun. The onion itself grows underground which means while they grow they do not come into contact with the sun so chloroplasts in an onion is pointless since they can’t undergo photosynthesis. Hope I helped!

The second stage of the calvin cycle needs an input of energy to reduce the 3pg molecules that resulted from the first stage. wh
Colt1911 [192]
<h3><u>Answer;</u></h3>

ATP and NADPH that were supplied through the light reactions

<h3><u>Explanation</u>;</h3>
  • <em><u>Calvin cycle reaction is the portion of photosynthesis that takes place in the stroma of chloroplasts and can occur in the dark; it uses the products of the light reactions to reduce CO2 to a carbohydrate.</u></em>
  • The Calvin cycle is divided into three portions: CO2 fixation, CO2 reduction, and regeneration of RuBP. Because five G3P are needed to re-form three RuBP, it takes three turns of the cycle to have a net gain of one G3P. Two G3P molecules are needed to form glucose.
