Answer:

Water will move to the left side of the beaker to dilute the sodium on the left side. Solutes will go from a higher concentration to a lower concentration.

Eukaryotic chromosomes:______

kherson [118]

Answer:

I think it is: C

Consist of both DNA and Protein

Explanation:

The reason why i say C is because Eukaryotic chromosomes consist of a DNA-protein complex that is organized in a compact manner which permits the large amount of DNA to be stored in the nucleus of the cell. The subunit designation of the chromosome is chromatin. The fundamental unit of chromatin is the nucleosome.

What were your controls for this experiment? what did they demonstrate? why was saliva included in this experiment?

Vlad1618 [11]

Positive control is Ginger root (should indicate the presence of amylase)

Negative control is Cellulose (should not contain amylase)

Here the presence of amylase is tested by testing the presence of starch using an IKI solution. Saliva is included in this experiment because it contains the enzyme amylase.

A complete plant gene containing four introns and five exons is carried on a 6.0-kb DNA fragment. DNA sequencing analysis finds

damaskus [11]

Answer and Explanation:

the total length of the gene is 6,000 base pairs (or) 6.0 kb and it has five exons, four introns and a 1,000 base pair length flanking region for the transcribed region.

Hence, each exon has (1500/5) = 300 by

each intron has (3500/4) = 875 by and

flanking segment (5' and 3') length for the transcribed region would be (1000/2) = 500 bp.

The gene segment is as shown in the <em>1st diagram attached below </em>

In eukaryotes, transcription takes place in the nucleus which results in the synthesis of hnRNA (heteronuclear ribonucleic acid). This hnRNA (pre-RNA) has both introns and exons, however when it is synthesized or while it is being synthesized the Spliceosomal complex removes introns from hnRNA and becomes converted into mRNA (messenger RNA) in the nucleus itself.

(<em>second diagram explains further)</em>

Now the synthesized mRNA reaches the cytoplasm. So, if mRNA collected from the nucleus and cytoplasm will have the same length of about 2,500 base pairs only. Therefore, after the commencement of northern blot analysis both mRNA will yield the same kind of result and have unique length.
