Answer:

4. A small ribosomal subunit binds with mRNA;

1. The first tRNA with Met binds to the P site;

3. tRNA comes in to the A site with a new aa;

2. A peptide bond forms between the new amino acid and a polypeptide chain;

5. tRNA in the P site leaves and the tRNA from the A site translocates to the P site.

Explanation:

The first step in translation i.e. protein synthesis is attachment of small ribosomal subunit i.e. 30S subunit with mRNA. Soon after that a tRNA charged with Met binds to the P site of 30 S ribosomal subunit. To this complex further 50S ribosomal subunit binds. Together all these components form '70 S initiation complex". Since this complex already has one amino acid (tRNA with Met) at the P site, in order to create peptide chain another tRNA charged with amino acid must enter the complex. The upcoming tRNA enters the initiation complex at A site. Next, due to the peptidyl transferase activity of large ribosomal subunit i.e. 50S subunit a peptide bond is formed between the amino acid at P site and amino acid at A site. Now since peptide bond has already been formed tRNA at P site is useless so it has to be expelled from the initiation complex via exit site. As soon as this tRNA is expelled, the tRNA which was at A site translocates into P site so that a new tRNA charged with another amino acid could enter the A site for further elongation of peptide chain.

Two linebackers tackle a quarterback. One hit him with a force of 105 N and the other hit him with a force of 150 N. They are bo
Setler [38]

The net force on the quarterback when he is hit by two linebackers running eastwards is 255N.

Force is a vector quantity, we must recall that if two forces act in the same direction, we obtain the net force by adding the two forces together. If two forces act in opposite direction, we obtain the net force by subtracting the forces from each other.

Since the both linebackers are running East, the net force is obtained as; 105 N + 150 N = 255 N.

Which statement is true regarding monocytes
vodka [1.7K]

Answer: <u>Option C, they digest pathogens</u>

Explanation: Monocytes are involved in the process of digesting pathogens and infected cells, termed as phagocytosis.

Monocytes don't produce antibodies, only B cells can produce antibodies. So, option A and D are incorrect. Also they appear colorless when observed under the microscope. They don't appear granular, so option B is also incorrect.
