Epithelium is connected to underlying connective tissue by

Brums [2.3K]

Answer:

The correct answer is: a basement membrane.

Explanation:

The basement membrane is a thin and fibrous membrane that is found under the epithelium and attaches it to the connective tissue. The basement membrane is composed of two membranes: the basal lamina (with laminin and collagen IV, among other proteins), and the lamina reticularis (that has collagen III making up reticular fibers). The basement membrane also has the function of a mechanical barrier that prevents the invasion of deeper tissues by malignant cells.

Epithelial tissue and connective tissue are two of the four basic tissues found in the body (the other two are nervous tissue and muscle tissue). Epithelial tissue makes up the skin and the inner lining of hollow organs (like the stomach or the trachea), and has multiple functions that are responsible for the function of the organ where it's located. Connective tissue is basically any type of tissue that connects the epithelium to muscle tissue or nervous tissue: from blood, to bone, and to fat.

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 1st diagram attached below

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.

(second diagram explains further)

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.
