ddNTPs have a hydrogen at 3' position which terminates synthesis of DNA.

ddNTPs is the abbreviated form for dideoxynucleotides triphosphates. They are known as chain elongating inhibitors. The Sanger method is a sequencing technique that is used to increase the number of DNA copies. The DNA synthesis requires magnesium ions, a single-stranded DNA template, oligonucleotide primer, and nucleotide precursors like dATP, dGTP, dTTP, and dCTP. Also, DNA polymerase is required which is an essential component for DNA synthesis.

The Sanger sequencing method is a significant process evident by its use in Human Genome Project which helped scientists in sequencing the human genome. The small sequenced fragments are joined together to form large regions subsequently forming chromosomes.

Where does the calvin cycle occur? there is a scheme of chloroplast structure. the outer layer of the chloroplast is labeled
Mashcka [7]
The Calvin cycle take place in the Stroma of the chloroplast. Calvin cycle is  a set of chemical reactions that take place in the chloroplasts during photosynthesis. This cycle is light-independent since it takes place after the energy has been captured from sunlight. The process; involves four main steps; carbon fixation, reduction phase, carbohydrate formation, and regeneration phase.

The pad of fatty tissue that covers the area of the pubic bone is called the ________.
Anettt [7]

The pad of fatty tissue that covers the area of the pubic bone is called the mons pubis

The pubic bone is protected by a fatty cushion called the mons pubis. The mons, or mons veneris in females, is another name for it. Although both have a mons pubis, females tend to have it more pronounced.

Females tend to have a large mound of tissue that is typically covered in pubic hair. During sexual contact, the mons pubis serves as a source of cushioning. Sebaceous glands that release pheromones to promote physical attraction are also found in the mons pubis.

The mons pubis is a part of the vulva. This is the rounded region in the bottom portion of the belly that is in front of the pubic bones (abdomen). At puberty, it grows hair all over it. The vulva has two skin folds.

pshichka [43]

Answer:

Explanation:

bacteria with No Plasmid -----------------will grow ONLY in medium without ampicillin.

"nonrecombinant gene, recombinant plasmid with vgp gene,", recombinant plasmid but no vgp gene-----------------------will grow in both media".

it means Plasmid have ampicillin resistance gene. So if we use medium with ampicillin so it will allow the growth of only those bacterai which have transformed plasmid (containing amp resistance gene).

 so having gene or not, recombinant or recombinant dosnt matter,  all the other s will grow in both type of medium as far as plasmid is transformed in to it.

How does decreasing light intensity affect rate of photosynthesis in vascular aquatic plants?
atroni [7]
It affects it by the increase of light intensity it increases the rate of photosynthesis but after the light intensity reaches its certain level the plant reaches its maximum rate of photosynthesis and photosynthesis occurs in the chloroplast.
