Answer;

a segment of chromosomal DNA

Explanation;

A gene is a  hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.

It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins.  However, many genes do not code for proteins.

Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

What structural component gives arteries the ability to passively adapt to changes in blood pressures that accompany the heartbe
Andrews [41]

Answer: elastic fibers

Explanation:

Elastic fibres are the essential durable component present in mammalian connective tissueand functions to provide proper pulmonary,  cardiovascular and intestinal system structure and function. Their structural function is to provide elastic recoil and resilience for the tissues.

Elastin fibers ahve two main including microfibrils and elastin containing fibrillin play a mechanical and structural role in the arteries, and their important function is to provide the tissues with resilience and elasticity.

Hence, elastic fibers helps arteries to adapt to changes in blood pressures that accompany the heartbeat.

During DNA Replication, a DNA strand that has the bases 3'ATACGC5' produces a strand with the bases
Gemiola [76]

During DNA Replication, the DNA strand that has the bases 3'ATACGC5' produces a strand with the bases 5'TATGCG3'  

Answer: Option B

<u>Explanation:</u>

The DNA Replication produces the newly formed two complimentary base pair strand from the two template base pair strand, so basically the already existing DNA strand is replicated, in order to produce complimentary DNA strand, with the template giving one strand to new each.

Thereby, here the given base was 3' ATACGC 5' so the first thing to produce the strand will be that the coding end will be reversed so the 3' end will have 5' end and 5' end will have 3' end. Then A bonds with T and T bonds with A and, so C bonds with G and G bonds with C, therefore, ATACGC will produce TATGCG. Thereby, answer would be 5'TATGCG3'.
