Give the sequence of mRNA that would match the following DNA strand

sladkih [1.3K]

Answer:

Below

Explanation:

mRNA is a complimentary copy of a DNA segment (gene) and consequently can be used to deduce the gene sequence. For converting a sequence from mRNA to the original DNA code, apply the rules of complementary base pairing: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A).

The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain. The anticodon is the complementary three nucleotide sequence in the appropriate tRNA.

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

_____ is the oldest possible age that members of a species can attain, whereas _____ is the number of years the average newborn

tankabanditka [31]

Maximum life span is the oldest possible age that members of a species can attain, whereas average life expectancy is the number of years the average newborn in a particular population group is likely to live.

<h3>What is life span? </h3>

Every living organisms pass through birth, growth, reproduction, old age, death. this period is called as life span.

<h3>What is death? </h3>

When all life activities are stopped in an individual organisms due to various reasons like ageing, disease, accidents, etc. it is called death.

Also some fully grown living organisms divides physically into two daughters, thus ending its independent existence.

<h3>What is living? </h3>

The objects with specific form and structure exhibits growth, development, reproduction, responsiveness and other unique characteristics of life. it is called living beings.

The living world is wonderful with wide range of living organisms. the earth is populated by various types of plants and animals.

Life is a complex organization of chemical molecules that express itself by chemical reactions leading to specific characteristics like cellular structure, growth, development, reproduction, adaptation, consciousness, death, etc.

<h3>3. A radiograph of a horse's frontal fetlock joint is called a dorsopalmar (PD) view.</h3>

Dorsopalmar (PD) view The horse's frontal fetlock joint demonstrates dislocation of the antebrachiocarpal joint with soft tissue swelling around the carpal joint

<h3>5. When performing surgery on the digestive system, we must ensure that the suture is well closed. </h3>

Yes. Endoscopic suturing is a procedure performed 100% by endoscopy, a procedure that inserts a flexible tube through the patient's oral cavity and reaches the structures of the digestive system. It is a non-invasive, safe process that does not require any cutting.

<h3>6. Oblique positions are sometimes used in radiographs.</h3>

Yes. Right and Left Anterior Oblique Positions (RAO and LAO) These terms refer to oblique positions in which the right or left anterior side of the body is close to the RI, and can be in an upright or recumbent position.
