labwork [276]

Answer:

The major structural difference between chromatin and chromosomes is that the latter are more organized and condensed.

Explanation:

Chromatin is genetic material packaged into a complex by special proteins (histones). That complex is in the form of uncoiled structures, so chromatin fibers are long and thin. Chromatin structure is permissive to DNA replication, transcription and recombination events.

On the other hand, chromosomes are highly condensed structures of genetic material that are formed just before the cell division.

Which mutation is an example of an insertion mutation?
Burka [1]

Answer:

d. AAU CCG CAU UGG A​

Explanation:

A mutation is any change or alteration to the sequence of a gene. There are, however, different types of mutation depending on how it occurs in the gene. One of these types is INSERTION MUTATION as mentioned in this question. Insertion mutation is a type of mutation in which one or more nucleotide base is added to the sequence, hence, changing the reading frame of the original sequence.

In this question, the original mRNA sequence is given as: AAU CCG CAU GGA.

An insertion mutation will cause nucleotide base(s) to be added to this sequence, which will be noticed by an increase in number of bases in the sequence.

The correct answer is: AAU CCG CAU UGG A​. In this mutated sequence, nucleotide "U" has been added to the sequence.
