Answer:
A
Explanation:
Golgi apparatus is an organelle in eukaryotic cells that stores and modifies (might include addition of sugar groups) proteins and lipids for certain functions and prepare them for transport to other parts of the cell.
In the Endoplasmic reticulum, proteins fold into into their correct shape. Some of them are transported to the Golgi apparatus in membrane vesicles. Some proteins need to do their jobs in the Golgi (they are said to be Golgi-resident). They are transported from the golgi appratus to their final destinations through a secretory pathway. It involves sorting proteins into different kinds of transport vesicles, which emanate from the trans Golgi network and deliver their contents to the appropriate cellular locations.
Proteins that are membrane embedded are conveyed to the plasma membrane (integral membrane proteins) by constitutive secretion. Proteins can divert from constitutive secretion pathway and be targeted towards other destinations such as lysosomes (as lysosomal proteins) and regulated secretion from cells (to the cell exterior).
Answer:
During translation process tRNA move from one binding site of ribosome (A site) towards P site.
Explanation:
Ribosome is composed of two sub units, one small and other large. It contain three binding sites for tRNA.
1. Peptidyl site:
It help in holding newly growing polypeptide chain of amino acid.
2. Acceptor site (A site):
It help in receiving and holding aminoacyl tRNA which hold amino acid that will be added to polypeptide chain.
3. Exit site (E site):
That site where tRNA leave its amino acid.
The process of translation consists of three main steps:
1. Initiation:
In this step mRNA bind to ribosomal sub unit.
2. Elongation:
The ribosome read the mRNA by joining with tRNA and help in the formation of polypeptide chain.
3. Termination:
When ribosome reach to stop codon translation stop.
When the process of translation is started, initiator tRNA carrier of methionine amino acid come and set on start codon (AUG) located in A binding site of larger subunit of ribosome. As ribosome move along mRNA attached tRNA to mRNA is shifted to p site from P to E site. It should be cleared that prolypeptide chain grow in nitrogen to carboxyl direction.
Answer:
organism, the leopard frog is an organism made up of other tissues and organs.
"Protostome" is the one type of invertebrate among the choices given in the question that this statement describes. The correct option among all the options that are given in the question is the first option or option "A". I hope that this is the answer that has actually come to your real help.
Answer:
Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. A pigment is a molecule that has a particular color and can absorb light at different wavelengths, depending on the color.
