Because the information of the DNA is wound tightly around histones, reducing the space taken up by the DNA.

Explanation:

Some of the sequence of DNA given is in 3' to 5' direction, mRNA sequence is also given.

The DNA is double stranded helix which replicates by semi conservative mode. The two strands unwind to act as a template for other strands. In transcription the 3' to 5' strand acts as a template because RNA synthesis takes place in 5' to 3' direction. mRNA is single strand. It has nucleotides in it from which 3 base pairs acts as a code for amino acid.

The following table shows DNA strand having complementary sequaence and mRNA synthesized.

eduard

Answer:

Vulvodynia

Explanation:

Vulvodynia is the medical term used to describe a chronic condition of long-lasting, severe pain around the vaginal orifice, which feels raw. Medically, the severe pain lasts for at least three months either constantly or occasionally. The pain could be generalized throughout the entire vulva or localized to a certain area of the vagina like the opening of the vagina.

Vulvodynia is usually doesn't have an identifiable cause, because it usually not traced to an infection.

Compare and contrast passive transport with active transport

ivann1987 [24]

Active transport uses energy passive transport does not..... active transport moves from lower to higher concentration and vice versa in passive transport.... both use carrier proteins....
