AURORKA [14]2 years ago

Identifying the genetic sex of a child is based on finding intracellular Barr bodies that consist of inactive chromatin material.

Inactive chromatin material is the one where no transcription takes place. It is also known by the name heterochromatin. It appears as a dark condensed form in the chromatin.

Barr bodies are the inactive X chromosomes. These are mad inactive by a process termed as lyonization. It is essential to make the chromosome inactive in organisms with XY type of sex determination. They are present at the periphery of the nucleus. Inactivation of X chromosome makes the amount of X chromosomes equal in both, males and females.

Please explain the difference between a frameshift mutation and a base substitution mutation.
harina [27]

Answer:

A frameshift changes every codon past it. A base substitution only changes one codon.

Explanation:

DNA is comprised of nucleotides (A, C, T, G) that make up amino acids. Every three bases is called a codon and represents an amino acid.

In a frameshift mutation, a nucleotide is either added or deleted from the sequence. This offsets the entire sequence after it because the reading frame shifts. Here's an example:

ACTGCTATCGTCATC

If another T is added in between the first and second codons, then every codon after will be changed.

ACT>T<GCTATCGTCATC

A substitution mutation is usually less severe, as it only alters one codon in the sequence. These occur when one nucleotide is replaced by another one. Here's an example:

ACTGCTATCGTCATC

Let's say the first G is replaced by a T.

ACT>T<CTATCGTCATC

As you can see, none of the other codons changed.

Typically, a frameshift mutation is considered worse than a substitution mutation.

What innate immune component is directly responsible for the lysis of the cell membrane of invading microorganisms?
larisa86 [58]

Answer:

The name of the innate immune component is MEMBRANE ATTACK COMPLEX.

Explanation:

The membrane attack complex is a type of structure that is usually formed on the surface of the cell membrane of invading pathogens due to the activation of the immune system. Membrane attack complex is also known as terminal complement complex. Individuals that lack this immune component due to mutations usually experience recurrent infections.

Explain, using natural selection, how the beetle population will adapt over time.
Julli [10]

Answer:

Over time the beetle population will adapt as a result of natural selection because the beetles "desired" by the birds will be eaten and their population will dimish as a result. The beetles that are not eaten by the birds will have a chance to allow their population to grow because a. they aren't being eaten and b. they have more space as the other colored beetle's population is shrinking. Causing the eaten species to become less prominant and the not eaten beetle's population to grow and take over in place of the other beetles.
