A key part of the Watson-Crick model came when Watson realized
that adenine could form hydrogen bonds with thymine and guanine
could form hydrogen bonds with cytosine. This explains why A=T
and G C in Chargaff's rules. Also, these two hydrogen-bonded
nucleotide pairs had the exact same width, so they could form the
rungs of the DNA ladder.
The fact that these pairs could match up only in this way meant that
the sequence of bases in one strand could determine the sequence
of bases in a second strand created from the first. The second strand
is said to be complementary to the first strand. Individual bases are
paired so that the identity of any base determines the identity of the
base paired with it; that is, the complementary base.
This table lists the base abbreviations for bases in a sample of single-
stranded DNA. Fill in the second column with the base abbreviations
that are complementary to the given bases.

Answer:
A–T
T–A
T–A
C–G
A–T
G–C
G–C
C–G
T–A
A–T
Explanation:
A always pairs up with T
C always pairs up with G
A - TT - AT - AC - GA - TG - CG-CC - GT - AA - TA usually pairs up with TC usually pairs up with GThese are bases of amino acids called nucleotides sequences. And this helps in the bond of several base pairs to their nucleotide sequence.What is the Watson-Crick model?
In “A Structure of Deoxyribose Nucleic Acid,” Watson and Crick defined DNA as a double helix that contained long, helical strands wound together. In their model, every DNA strand contained personal devices referred to as bases, and the bases alongside one DNA strand matched the bases alongside the opposite DNA strand.
Thus it is clear that the above answer is well explained.

Based on the the table of rock characteristics and your knowledge of the rock cycle, in which type of
rock (igneous, metamorphic, or sedimentary) would you expect to find bubbles or a smooth, glassy
surface? Why?
HELPPPP ASAP
Answer:
The answer would be igneous. But there are two types of igneous rocks. One is Intrusive, or Plutonic, rocks, and the other is Extrusive. Intrusive rocks crystallize from magma beneath the earth's surface. Extrusive or volcanic rocks crystallize from lava at the earth's surface. Either way, Igneous would have a bubbly, or a smooth, glassy surface.

Why is the reduction in chromosomes number important in meiosis?
Explanation:
Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.

Answer: Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
Explanation:
DNA is found in the nucleus of eukaryotic cells and the ribosomes, the location where proteins are made, are found out in the cytoplasm of the cell as show below. Explain why this is a problem and how the cell solves this problem.
Answer:
See the answer below
Explanation:
The DNA of eukaryotic organisms being present in the nucleus while the protein-synthesizing organelle, the ribosome being present in the cytoplasm poses a spatial problem. It means that transcribed DNAs (messenger RNA) in the nucleus would have to somehow be transported to the ribosome in order for the cell to successfully synthesize proteins.
The problem of transporting the messenger RNA is solved by two features of the cell:
The presence of pores in the nuclear envelopThe presence of transport proteins in the nucleusThe mRNA binds to the transport proteins to form mRNA-protein complexes and is transported through the nuclear pores, often with the assistance of ATP.
how does an increase in volume affect the gas pressure in a balloon
Answer:
Boyle's Law explains the relationship between volume and pressure. According to Boyle's Law, the volume of a fixed amount of gas decreases as its pressure increases. If the volume increases, its pressure decreases.

.A jogger with a mass of 81.6 kg is moving at 2.2 m/s. What is the jogger's
kinetic energy
Answer:
89.6Joules
Explanation:
Kinetic energy is 1/2MV^2
Where m is Mass and v is velocity.
M=81.6 v=2.2m/s
K.E= 1/2 × 81.6 × 2.2
= 81.6 ×1.1
K.E=89.6 Joules
circle with center at (-3, 7) and radius 8
Explanation:
Centre of the circle ( h,k)=(-3,7)
radius of the circle (r)=8
Equation of the circle is,
(x-h)^2+(y-k)^2=r^2
or,(x+3)^2+(y-7)=8^2
or,x^2+6x+9+y^2-2y+49=64
or,x^2+y^2+6x-2y+58-64=0
or,x^2+y^2+6x-2y-6=0 is the required equation of the circle

A.
Calvin cycle
B.

D.
Krebs cycle
Explanation:
The answer is D. Krebs cycle. the Krebs cycle only occurs when oxygen is present, and so it would seem to be the same for the electron transport system... although, in anaerobic bacteria, it is still used as a respiratory electron transport chain called physolmere.
