What important function is happening in the S phase?
daser333 [38]

Answer:

The answer is D. Synthesizing DNA.

Explanation:

The synthesis (S) phase of the cell cycle is of critical importance to precisely replicating the genomic information encoded in the nucleus of the cell.

The major work of the S phase of the cell cycle is replicating the entire complement of DNA. To do this, the cell activates pre-replication complexes to make replication origins. These are simply areas of the DNA where replication will begin.

Carbohydrates contain carbon characterized by the atomic grouping H-C-OH and
scZoUnD [109]

Answer:

true

Explanation:

Carbohydrates, like all organic molecules, always contain carbon (C) and hydrogen (H) atoms. Carbohydrate molecules are characterized by the presence of the atomic grouping H-C-OH, in which the ratio of hydrogen atoms (H) to oxygen atoms (O) is approximately 2:1. Because this ratio is the same as the ratio in water, the name “hydrates of carbon” seems appropriate. Carbohydrates first and foremost function for quick, short-term energy storage in all organisms, including humans.

Explain how a testcross can provide evidence for or against linkage.
MrRa [10]

Answer:

Testcrosses clarify linkage because each phenotypic class of progeny corresponds to each gamete type produced by the dihybrid parent.

Explanation:

  • A test cross involves the crossing of an individual with another phenotypically recessive individual so as to determine the zygosity of the former by analyses of the proportions of offspring phenotypes.
  • In order to determine linkage, the test cross shows that if the parentals are more than the recombinants, we can say that the two genes such as b and c  are genetically linked and therefore, they must be on the same chromosome.
  • Also, the test-crosses help to find out which alleles came from which parent.
  • By setting up testcrosses in which one parent is homozygous for the recessive alleles of both genes,we can analyze the gene combinations received in the gametes from the other, doubly heterozygous parent.

What number represents a Ribosome? What is the function
Oduvanchick [21]

Answer:

A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during the process called protein synthesis or translation. The process of protein synthesis is a primary function, which is performed by all living cells. Ribosomes are specialised cell organelles and found in both prokaryotic and eukaryotic cells. Every living cell requires ribosomes for the production of proteins
