How could this mRNA sequence support a triplet code? ACACACACACAC

Biology
1 answer:
ANTONII [103]2 years ago
7 0

Answer: When the triplet code ACACACACACAC is translated in such conditions, it will produce a polypeptide chain consisting of multiple copies of only one type of amino acid.

4. A wave traveling at 200 m/sec has a wavelength of 2 meters. What is the
dalvyx [7]

Given that,

The speed of a wave, v = 200 m/s

Wavelength, \lambda=2\ m

We need to find the frequency of this wave. The relation between wavelength, frequency and the speed is given by :

v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{200\ m/s}{2\ m}\\\\f=100\ Hz

So, the frequency of this wave is 100 Hz.

In a certain mutant strain of bacteria, the enzyme leucyl-tRNA synthetase mistakenly attaches isoleucine to leucyl-tRNA 10% of t
Effectus [21]

Answer:

The correct answer is "proteins in which isoleucine is inserted at some positions normally occupied by leucine".

Explanation:

The missing options of this question are:

A. proteins in which leucine is inserted at some positions normally occupied by isoleucine.

B. proteins in which isoleucine is inserted at some positions normally occupied by leucine.

C. no abnormal proteins, because the ribosomal translation machinery will recognize the inappropriately activated tRNAs and exclude them from the translation process.

D. no proteins, because the inappropriately activated tRNAs will block translation

The correct answer is option B. "proteins in which isoleucine is inserted at some positions normally occupied by leucine".

In normal conditions, the enzyme leucyl-tRNA synthetase attaches one leucine amino acid to leucyl-tRNA as part of synthesis of proteins that have one or more leucine residues in their sequences. Since the enzyme of this mutant strain of bacteria mistakenly attaches isoleucine to leucyl-tRNA 10% of the time, approximately 10% of all the proteins that normally have leucine residues will going to have isoleucine. Therefore, These bacteria will synthesize proteins in which isoleucine is inserted at some positions normally occupied by leucine.

A learner says that Earth rotates on its axis as it revolves around the sun in a circular orbit and that the sun is at the exact
bonufazy [111]

The earth’s orbit around the sun is a perihelion. The orbit is also  not a true elliptic circle because the orbit is influenced by other nearby celestial orbits such as the planets in the solar system. On occasion, the orbit is deformed putting a particular part of the earth’s orbit closer to or farther from the sun. Also, the barycentre of the solar system changes as the alignment of the solar system’s celestial bodies varies over time.
