Answer:

The correct option is B) Missense mutation.

Explanation:

A missense mutation can be described as a type of point mutation in which a mutation in a single nucleotide causes the codon to change and form a different type of amino acid. As in the above scenario, we can see that the code CAU coded for the amino acid, Histidine, before a point mutation occurred. After the point mutation, the codon was changed to UAU instead of CAU. UAU codes for the enzyme, tyrosine, instead of histidine.

Answer:

to maintain homeostasis

Explanation:

The bionic pancreas is a technology created to reduce and adjust blood sugar levels in patients with diabetes. This external device was developed by Ed Damiano's lab at Boston University. This management system is well known to maintain homeostasis by managing blood sugar levels: the bionic pancreas contains two pumps, one with insulin and the second one with glucagon for controlling the sugar levels when they change in the blood.

Are the organelles that process coded genetic messages and assemble amino acids into proteins

g100num [7]

Answer

Ribosome is an imporatnat cell organelle that play a key role in protein synthesis.

Discovery

Ribosome was discovered by Palade in 1955.

Structural composition

Chemically it is composed of an equal amount of rRNA and proteins, thats why it is also known as ribonucleoprotein.

Sub units of ribosomes

Ribosome is composed of two sub units one is smaller and the other one is larger. Both units are attached with each other with help of Mg atom.

Size of ribosome

In prokaryote the ribosome size is 70S, while in eukaryotes its size is 80S.

Polysome

When many ribosomes are attached to one mRNA strip it is called polysome or poly ribosome.

Role of ribosome

Ribosomes are the sites of synthesis of protein from amino acids.

Mechanism

mRNA which is the exact copy of DNA and formed in transcription come out from nucleus and attached to ribosomes. Now tRNA catch amino acids and come toward ribosome where its anti code match with genetic code of mRNA and then bonded to it. In this fashion a lot of amino acids are accumulated which make bonds with each others. Thus message present on mRNA in the form of genetic codes convert into protein through the process of transliteration.
