Suppose that rat liver expresses a protein called Yorfavase. This enzyme is composed of 192 amino acid residues, and thus the co

irakobra [83]

Answer:

Centromeric DNA

Explanation:

Genes are responsible for formation of proteins. A codon produces a single amino acid and it comprises of three base pairs. The whole DNA of organism does not contribute to encode protein. There are sequences in DNA that does not contribute in coding known as non-coding DNA and perform different functions. These may include the O O O 5-end, DNA coding for a signal sequence, noncoding intron and O promoter sequence .

The centromere is the part of DNA that links the sister chromatids. The centromere is not converted to mRNA or proteins. It is also not involved in regulation of genes. So it did not contribute to 864 bp found in the yfg gene.

Describe the role of the carrier molecule nadp in photosynthesis

Eduardwww [97]

Answer:

The high energy electrons from chlorophyll to other molecules are transferred by this molecule.

Explanation:

NADP is an important molecule which is used in the production of energy in the form of ATP. During the process of photosynthesis it acts as a universal electron carrier. It accepts electrons and hydrogen atoms to form NADPH. NADPH then moves to the other location of reactions and there it donates the energy stored in bonds along with hydrogen and electrons to other molecules and again becomes NADP.

Which diagnostic test is used for the direct visualization of ligaments, menisci, and articular surfaces of joints?

Sati [7]

Arthroscopy is done for direct visualization of the ligaments, menisci, and articular surfaces of the joints. Thus, option A is correct.

<h3>What is the role of ligament?</h3>

Ligaments are type of connective tissue which help to connect bones, joints and organs. It provide support internal parts of the body.

It is made of a band of connective tissue, collagenous fibre and spindle-shaped fibrocytes which is an elastic fibers.

Ligaments holds bones together, stabilize it, provide strength to joints etc.

By the use of Arthroscopy doctors can diagnose and treat the joint’s structural problems like any dysfunction. Hence, Option A is correct.

When only skeletal remains are available for identification, the gender of the deceased individual can be determined by:?

zlopas [31]

The answer would be skeletal markers and DNA analysis.

Skeletal markers are often used to identify the biological gender of skeletal remains. The most commonly used skeletal markers can be observed in the skull and in the pelvic bone.However, the accuracy of his method is limited to adults only the differences between male and female skeletal markers usually become visibly only after maturation.

DNA analysis is more widely uses nowadays because with the technology of today, laboratories can now detect and X and Y chromosome-specific sequences, which help them identify the biological gender.

The two chickens below are bred together. Which of the following is a possible set of offspring for these parents?One red chicke

GalinKa [24]

The provided question is incomplete as the cross in between parents, however the cross between in red and white bred parents.

Answer:

The correct answer is : five red/white chickens.

Explanation:

Parents should be homozygous for feather color, each offspring will inherit F from one of the parent, and the f allele from parent 2. So, every offspring will have the genotype F and f and will have white and red fathers.

Thus, the correct answer is : five red/white chickens.
