In

a molecule of double-stranded DNA, the amount of adenine present is always equal to the amount of

cytosine

guanine

thymineuracil

Slide11

The

diagram below shows Rosalind Franklin’s x-ray diffraction image of DNA

.

How did this evidence affect the work of Watson and Crick?

It was used to show that DNA was the molecule of inheritanceIt was used to develop the theory of independent

assortment

It was used to identify the four bases that make up

DNA

It was used to determine the physical structure of DNA

Semi-conservative

replication of DNA refers to the idea that

each half of the original DNA molecule is joined with a new complementary DNA

strand

each new DNA molecule contains two new single RNA strandsDNA molecules need to unwind before duplication

begins

the two strands of DNA molecules run in opposite

directions

of the following activities occurs in the G1

phase?

growth of the

cell

replication of the

DNA

formation of the mitotic

spindle

Which

of the following features of DNA is

most important

in determining the

way an organism looks?the direction of the helical twistthe number of

deoxyribose

sugars

the sequence of nitrogenous

bases

the strength of the hydrogen

bonds

Slide24

23. What phase of Mitosis is this?

Prophase

Anaphase

Metaphase

Cytokinesis

Telephase

Slide25

24. Why must the cell divide?

Too many demands on DNA if to big

Hard to exchange material if to big

Volume increases more rapidly than the surface

area

All of the above
