Chromosomal aberrations are of many types. They are different from each other because:

• Deletion: In this, deletion or disappearance of a specific sequence of a chromosome occurs.

• Duplication: It duplicates the specific part of a chromosome and leads to extra genetic material.

• Translocation: In this one portion of a chromosome is transferred to another chromosome.

Further Explanation:

Chromosomal aberration is referred to as abnormality in the sequence or the arrangement of the chromosome. These abnormalities affect the normal function of the chromosome. It can develop mainly due to two reasons one condition is developed due to abnormalities in the number of chromosomes. One of the examples is Down syndrome that is developed due to the presence of one extra chromosome. Another example of this is turner syndrome that is developed due to the loss of one chromosome. These problems are referred to as numerical aberration.

Another condition is developed due to Structural aberration. In this, the specific sequence is affected. Some examples of structural aberration are:

• Deletion: In this, the particular sequence is missing from the chromosome.

• Duplication: In this, some part of the chromosome is duplicated.

• Translocation: In this, part of the chromosome is moved to another chromosome.

following a meal, glucose must move from the gut lumen, where there is a high glucose concentration, through membrane proteins a

True [87]

Following a meal, glucose must move from the gut lumen, where there is a high glucose concentration, through membrane proteins and into intestinal cells, where there is a relatively low level of glucose. this movement is called <u>diffusion</u>

This is simply because glucose moves from a region where it is highly concentrated in the gut lumen to a region of less concentration in the intestinal wall.

<h3>Diffusion</h3>

Diffusion can simply be defined as the movement of substances from a region of high concentration to a region of low concentration.

So therefore, Following a meal, glucose must move from the gut lumen, where there is a high glucose concentration, through membrane proteins and into intestinal cells, where there is a relatively low level of glucose. this movement is called diffusion

What molecules link together to form proteins

Lady_Fox [76]

Answer:

Peptide bonds

Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

Which of the following features of the trp operon is most essential to the process of attenuation independent of the repressor p

diamong [38]

Answer:

The ability of sequences within the leader mRNA to pair with one another and form stem-lopp structures

Explanation:

A form of feedback regulation controls the trp operon by regulating transcription termination, a mechanism referred to as Attenuation.

-In the presence of high concentrations of tryptophan, RNA polymerase ceases transcription shortly after initiation in a region called the leader sequence.

-If the concentration of tryptophan is low, transcription does not terminate until the entire operon is transcribed. The mechanism of attenuation links alternative RNA secondary structures to transcription termination.

-Immediately after transcription, RNA from the leader region folds into one of two alternative secondary structures.

-One of these structures is a transcription termination signal that stops RNA polymerase from continuing to the end of the operon.

-The alternative structure does not contain a transcription termination signal and allows transcription of a single mRNA that encodes all the structural genes.

-The decision as to which of the two alternative RNA structures formed is regulated by the concentration of tryptophan.
