Knowing that the second polynucleotide strand of DNA complements and or base pairs with that of the original strand, based on the base pairing rules as shown:

A - T
G - C

Then the complementary strand would be :

Answer: The complementary strand for given sequence of DNA is TAGCCAT.

There are two complementary strands that are present in a double helical structure of DNA.

According to Watson and Crick base pairing-

Adenine (A) forms base pair with Thymine (T) and Guanine (G) forms base pair with Cytosine (C) in a double stranded DNA molecule.

As per the question, sequence of one strand is given that is ATCGGTA.

Therefore, the sequence of complementary strand is TAGCCAT.

AnnZ [28]

Answer:

The options

A. It suggested that DNA is the

"transforming principle."

B. It confirmed that DNA is a double helix composed of two antiparallel strands.

C. It demonstrated that DNA consists of four nucleotides where the proportions of adenine/thymine and cytosine/guanine remain constant.

D. It proved that DNA is

semiconservative replication.

The CORRECT ANSWER IS A.

A. It suggested that DNA is the

"transforming principle."

Explanation:

A. It suggested that DNA is the

"transforming principle."✔

Griffith's experiments proved

that transformation can be seen in

pneumococcus, but gave no proof based on what molecular background the transformation was

WHILE, the Avery MacLeod-McCarty experiments proved that DNA was THE TRANSFORMING PRINCIPLE.

B. It confirmed that DNA is a double helix composed of two antiparallel strands.❌

These findings were established by James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin

C. It demonstrated that DNA consists of four nucleotides where the proportions of adenine/thymine and cytosine/guanine remain constant.❌

The findings was established by Erwin Chargaff.

D. It proved that DNA is semiconservative replication.❌

The findings was established by Matt Meselson and Franklin Stahl.

What is the difference between fibrous protein and globular protein

BARSIC [14]

Answer:

Fibrous proteins are generally composed of long and narrow strands and have a structural role.

Globular proteins generally have a more compact and rounded shape and have functional roles.

Explanation:

fibrous proteins ARE something, whereas globular proteins DO something.

avanturin [10]

Answer:

Explanation:

We can easily move the box from a ground floor though to the first floor at an angle of 40° to the horizontal by simply pushing the load through an inclined plane. We will simply be lean the inclined plane on the building at the required angle and the push through the the height of the building.

Based on the explanation above, the best type of simple machine to use is an INCLINED PLANE. <em>Note that the essence of using a machine is simply to make our work easier and faster and also be able to overcome a much larger load with a minimal effort. </em>

What property of the DNA molecule explains the necessity for Okazaki fragments? DNA is antiparallel. DNA is a linear molecule. D

Arada [10]

Answer:DNA is antiparallel.

Explanation: DNA is a double stranded helix in which the two strands are antiparallel. Being antiparallel means that as one strand runs from 5'->3' direction, the other strand runs from 3'->5' direction. During DNA each of the two strands serves as a template for a new complementary strand. The synthesis of a new DNA strand is always in the 5'->3' direction, therefore one strand is synthesized continuously in the direction of the replication fork while the other strand is synthesized discontinuously in the direction opposite to the replication fork in short fragments called the Okazaki fragments. The strand that is synthesized continuously is called the leading strand while the strand that is synthesized discontinuously in Okazaki fragments is called the lagging strand.
