 They are thought to have different paths of evolutionary development.

I believe this is because Archaea differ from bacteria in a number of ways. These includes;
Unlike bacteria, archaea cell walls do not contain peptidoglycan, Archaea have different membrane lipid bonding compared to Bacteria and Eucarya. That is Archaeal lipids lack the fatty acids found in Bacteria and Eukaryotes and instead have side chanis composed of repeating units of isoprene. Other differences are like Bacteria, Archaea have 70 S ribosomes, but they have a different shape; Archaea have more complex RNA polymerases than Bacteria, similar to Eucarya.

6 steps of translation in order biology
densk [106]

Answer:

step 1: mRNA attaches to the ribosome

step 2: tRNA's attach to free amino acids in the cytoplasmic "pool" of amino acids

step 3: tRNA carries its specific amino acid to the ribosome

step 4: tRNA "delivers" its amino acid based on complementary pairing of a triplet code (anticodon) with the triplet code (codon) of the mRNA

step 5: Enzyme "hooks" the amino acid to the last one in the chain forming a peptide bond

step 6: Protein chain continues to grow as each tRNA brings in its amino acid and adds it to the chain

Compare passive and active transport through the cell membrane, including energy use and concentration gradients.
sweet [91]
Passive transport vs active transport sounds like what it is. In passive transport, there is no energy needed to get the molecules across the cell membrane, whereas in active transport, energy is expended getting the molecules across the membrane. Basically in active transport the ATP in your cells gives one of it’s phosphates to the transport proteins in your cell membrane and it lets select molecules in. These molecules are moving through a concentration gradient during active transport(with the help of ATP), from an area of low concentration to an area of high concentration.

What molecule makes instructions for proteins and is located inside a eukaryotic nucleus
Afina-wow [57]

Answer:

DNA stores that info

Sonographic findings of severe micromelia, decreased or absent ossification of the spine, macrocephaly, and micrognathia describ
andrew-mc [135]

Answer: Option A.

Achondrogenesis

Explanation:

Sonographic findings of severe micromelia, decreased or absent ossification of the spine, macrocephaly, and micrognathia are conditions of Achondrogenesis because

Achondrogenesis is a genetic disorder that is as a result of mutations in gene SLC26A2 which is responsible for cellular transport proteins that is needed for the growth and development of bones and cartilage. This condition lead to malformation of bones and cartilage and it is characterized by short limbs, small body, narrow chest ,prominent abdomen,underdeveloped lungs,lack of ossification in the spine and pelvis, prominent head, small chin e.t.c.

It is a condition that affects infants.

The major treatment is pallative care in which the doctor have to reduce pain stress of bones and cartilage and also genetic councellling.
