Answer:

RNA has ribose, while DNA has deoxyribose.

RNA ha only one strand while DNA ha two complementary strands.

In RNA, there is uracil instead of thymine, like in DNA.

In a plant, leaf color and leaf shape are controlled by two linked genes Leaves of the wild-type plant are red. A recessive muta

Brrunno [24]

Solution :

Red is dominant over the white leaves and pointed is dominant over smooth.

Red = R , white = r

Pointed = P , smooth = p

Red, pointed x white,smooth ------ Parents

RRPP rrpp

RP rp ----------------- Gametes

RrPp -------- $F_1$

(red, pointed)

When this $F_1$ is test crossed,

RrPp x rrpp ---- $F_1$ test cross

Gametes → rp

RP ---------- RrPp - red, pointed - 36 parental type

Rp ---------- Rprp - red, smooth - 14 re- combination

rP ----------- rrPp - white pointed - 10 re- combination

rp ----------- rrpp - white, smooth - 40 - parental type

Total = 100

As this ratio is deviating from 1:1:1:1, it indicated the two genes are linked.

Linkage strength = percentage of crossing over = map distance between the genes.

Percentage crossing = recombination frequency = percentage of recombination.

Recombination frequency $=\frac{\text{total no. of recombination}}{\text{total no. of progeny}}\times 100$

$=\frac{14+10}{100} \times 100$

= 24 %

= 24 map units

How is muscle color related to muscle specialization?

kati45 [8]

Muscle color is related to muscle specialization because it indicates whether muscles are used more for aerobic or anaerobic metabolism. Aerobically respiring muscles that do work over a long period of time have more red oxidative fibers, while anaerobically respiring muscles that do work in bursts have more white glycolitic fibers.

Cytotoxic t-cell subpopulations are specialized to combat _______ pathogens, whereas helper t-cell subpopulations are specialize

Katarina [22]

Cytotoxic t-cell subpopulations are specialized to combat intracellular pathogens, whereas helper t-cell subpopulations are specialized to combat extracellular pathogens.

Cytotoxic t-cell are CD8+ cells. Cytotoxic t-cell uses granzymes to kill intracellular bacteria, that lives in the cytosol such as viruses. They identify the pathogen forgein peptids that are bounded to MHC-I on the cell surface.

cd4+ T helper (Th) cells include Th1, Th2, and Th17 cells. They contribute to aliergic reactions and fighting extracellular parasites.
