Which of the following cell organelles do both prokaryotic and eukaryotic cells have?A. Golgi apparatus

B. ribosomes

C. mitochondria

Answers

Answer 1
Answer:

Answer:

Option B, Ribosomes

Explanation:

Ribosome exists in both free state and also as a membrane bound organelle. Thus, ribosomes is found in both the eukaryotic and prokaryotic cells as it is an essential component that facilitates the translation of RNA and formation of protein.

Golgi apparatus and mitochondria are membrane-bound organelles and all membrane-bound organelles are found in eukaryotes only. Prokaryotes do not have membrane-bound organelles

Thus, option B is correct
Answer 2
Answer: They both have ribosomes, so the answer is B.

Review the numbered items below. Then, decide which of the following lists the correct steps of translation in the correct chronological order. I. UGA codon is identified.
II. DNA is unwound to expose a single template strand.
III. tRNA molecules carrying various amino acids bond to mRNA based on the sequence of mRNA codons.
IV. mRNA arrives at the ribosome
V. Introns are snipped out of an mRNA molecule.
V. tRNA, carrying methionine amino acid, bind to mRNA.

Answers

Answer:

IV, VI, III, I

Explanation:

Translation is the process of synthesis of protein from with the help of messenger RNA (mRNA).

The process of translation include initiation, elongation and termination.

  • Initiation: In this step mRNA binds to ribososomes and tRNA, carrying start codon or methionine binds to mRNA.
  • Elongation:In this step, the tRNA molecules carrying several amino acid bind to mRNA based on the sequence of mRNA codon and then moves (translocates) to the next mRNA codon which leads to amino acid chain.
  • Termination: At the end, when a stop codon (UGA) identified, polypeptide is released.

So, the correct chronological order is IV, VI, III, I.

Which of the following accurately describes the patterns of inheritance in human blood types?A. Two alleles code for blood types and four phenotypes are possible.
b. Allele IA and IB are codominant, and allele i is recessive.
c. Allele i is dominant over alleles IA and IB.
D. Three alleles code for blood types and three phenotypes are possible.

Answers

In human blood types two alleles are inherited ,one from each parent.
If the allele is i it is a recessive trait.
Blood types possible: A, B, AB, O.

D. Is wrong because you don't inherit three alleles and there is more than just one outcome possible.
C. Is wrong because i is recessive and IA and IB are both dominate.
B. Is wrong because IA and IB are not codominant.

A. Is right because two alleles from parents. Alleles do code for blood types. and their are four phenotypes possible: A, B, AB, and O blood types. 

Independent assortment of chromosomes is a result of A) the random and independent way in which each pair of homologous chromosomes lines up at the metaphase plate during meiosis I.
B) the random nature of the fertilization of ova by sperm.
C) the random distribution of the sister chromatids to the two daughter cells during anaphase II.
D) the relatively small degree of homology shared by the X and Y chromosomes.
E) the random and independent way in which each pair of homologous chromosomes lines up at the metaphase plate during meiosis I, the random nature of the fertilization of ova by sperm, the random distribution of the sister chromatids to the two daughter cells during anaphase II, and the relatively small degree of homology shared by the X and Y chromosomes.

Answers

The answer is A) the random and independent way in which each pair of homologous chromosomes lines up at the metaphase plate during meiosis I. 

The law of independent assortment is the second Mendel's law. In independent assortment the alleles for different traits are passed independently to the offspring. It occurs during meiosis I. When in metaphase of meiosis I the chromosomes line up, mother's chromosomes can be on one side, and father's chromosomes on the other side of the equator or they can be mixed in a number of ways.

What are the functions of the smooth and rough E.R.s

Answers

The endomembrane system is a group of cell membranes and organelles that are mutually interconnected, either by being directly continuous with one another or by sending one another vesicles—little spheres of membrane then can bud off from one membrane and fuse with another. 

The rough endoplasmic reticulum (rough ER) gets its name from the bumpy ribosomes attached to its cytoplasmic surface. As the ribosomes attached to the rough ER make proteins, they feed the newly forming protein chains into the lumen.

The smooth endoplasmic reticulum (smooth ER) does not have ribosomes on its cytoplasmic face.The smooth ER has a variety of functions, and its exact role may vary between cell types.

One role of the smooth ER is to produce lipids, including phospholipids, cholesterol, and steroids.

Explanation:

Nucleic acids are composed of:a: a phosphate group, a pentose sugar, a nitrogen base
b: a phosphate group, a pentose sugar, a carboxylic acid
c: a pentose sugar, a nitrogen base, an R group
d: a nitrogen base, an amino acid group, a carboxylic acid

Answers

Answer:

a phosphate group, a pentose sugar, a nitrogen base

Explanation:

nucleic acid is a polymeric macromolecule made up of repeated units of monomeric 'nucleotides' composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.
