For the numbered steps below, select the option that places them in the correct order. 1) The ribosome binds to the mRNA and uses tRNAs to translate mRNA into the corresponding amino acid polypeptide sequence. 2) The spliceosome removes introns. 3) The primary structure of the polypeptide chain undergoes hierarchical foldings to form the tertiary structure. 4) RNA polymerase binds to the promoter region of a gene and initiates transcription.

Answers

Answer 1

Answer:

first 4, then 2, then 1, and lastly 3

Explanation:

First, RNA polymerase binds to the promoter region of a gene on the DNA and initiates transcription. Transcription is the process by which we get mRNA (coding RNA) which is used as a template for protein synthesis. Then, in transcription, the resulting mRNA undergoes modification and maturation. This  involves removal of introns, addition of 3'-poly-A tail and 5'-cap. Introns are sequences that do not code for protein and are hence removed. The structure that removes introns is the spliceosome. Thirdly, mature mRNA travels to the cytoplasm. Ribosome (composed of rRNA) binds to mRNA and tRNA to start the process of protein synthesis. The process of formation of protein is called translation. Lastly, the primary structure of protein may undergo folding to form a tertiary structure.

Genetic variation is more commonly found in sexually reproducing organisms, as compared to asexually reproducing organisms, because
1 point
in asexual reproduction gametes fuse to lead to new genetic combinations
in sexual reproduction the gametes formed are all genetically identical
in asexual reproduction the gametes formed are genetically different
in sexual reproduction gametes fuse to lead to new genetic combinations

Answers

Answer:

In sexual reproduction gametes fuse to lead to new genetic combinations

Explanation:

In sexually reproducing organisms, there are two parents who create genetically diverse offspring.

This occurs because the gametes of the two parents combine to create very unique genetic combinations, which lead to increased genetic variation.

On the other hand, asexually reproducing organisms reproduce without a partner.

Their offspring are identical clones to the parent, so they have much less genetic variation.

So, the correct answer is that In sexual reproduction gametes fuse to lead to new genetic combinations.

Answer:

Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.

hope it will help

Here, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

What is Punnett Square?

The Punnett square is a tool used to predict the probability of offspring inheriting specific alleles from their parents. If all of the offspring exhibit the same phenotype (such as purple flower color), it is likely that the parents both carried at least one dominant allele for that trait. This would mean that the purple flower color allele is dominant. Here, the parents are both purple and white, so all the offspring are dominant in nature.

Hence, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

O B. DNA separates into two nuclei.

O C. The cell splits in two.

O D. Cytoplasm is manufactured.

Answers

Answer: A. Chromosomes are duplicated.

Explanation: This is the correct answer on the quiz.

Chromosomes are duplicated in S phase. Therefore, option (A) is correct.

What do you mean by S phase?

Between G1 phase and G2 phase, DNA replication takes place during S phase of the cell cycle. The processes that take place during S-phase are tightly controlled and highly conserved.

The cell replicates its genetic material entirely during the S phase of DNA synthesis; At the end of S phase, a normal diploid somatic cell with a DNA complement of 2N acquires a DNA complement of 4N.

DNA synthesis or replication occurs during the S phase of the cell cycle, which occurs prior to the interphase. Before entering mitosis or meiosis, the cell's genetic material is replicated in this manner, leaving enough DNA for daughter cells to divide.

Tissue that sustains, protects and provides structure to other tissues and organs in the body. Connective tissue also stores fat, permits the movement of nutrients and other substances between tissues and organs, and allows the repair of damaged tissue. Connective tissue exists created up of cells, fibers, and a gel-like substance.

Connective tissue is discovered in between other tissues everywhere in the body, including the nervous system. The three outer membranes (the meninges) that surround the brain and spinal cord exist composed of dense inert connective tissue.

Connective tissues bind systems together, form a framework and support for organs and the body as a whole, store fat, transport substances, defend against disease, and assist restoration of tissue damage.

Poikilothermic animals include types of vertebrate animals, specifically some fish, amphibians, and reptiles, as well as many invertebrate animals.

Reptiles are cold-blooded, or ectothermic, animals. This means that they cannot produce heat in their own bodies, and have to rely on their surroundings to keep warm. This is why most reptiles are found in hot or warm climates. Reptiles often bask in the sun to get warm.

Both reptiles and amphibians are poikilothermic, which means that they cannot regulate their own body temperatures internally as birds and mammals do.
