How many pairs of chromosomes exist in each of your cells?
jok3333 [9.3K]

Answer:

23 chromosome pairs.

Explanation:

In humans, the DNA strands are packaged in a tightly coiled 1400 nm structure called the chromosomes. Since each cell contains the DNA therefore each cell contains the chromosomes.

The human genome is packaged into 46 linear chromosomes but since the humans are diploid organisms, therefore, the chromosomes form pairs with the homologous chromosomes and form 23 pairs of chromosomes. Every cell of humans possesses 23 pairs of chromosomes.

Thus, 23 pair of chromosomes is correct.

How do hydrogen bonds between molecules explain why they are polar?​
valkas [14]

Processing of the mRNA begins before transcription of eukaryotic mRNA\'s is complete. The end of the mRNA is prepared for recogn
kompoz [17]

Answer:

The correct answer is

1. 5' end.

2. guanosine

3. 5′ to 5′ triphosphate linkage.

4. On the 7th position.

5. 2′ hydroxy-groups of the first 2 ribose sugars.

Explanation:

The eukaryotic mRNA is processed or modified with a guanosine cap at 5' end and poly-A tail at 3'end before translation.

The process of adding a cap at 5' end of a growing mRNA is known as capping. The process of capping adds guanosine nucleotide at the 5'-end of mRNAs by 5′ to 5′ triphosphate linkage. This guanosine is modified by methylating at the  7th position of the atom. The mRNA is further modified by methylation of first two ribose sugars at their 2′ hydroxy-groups. This capping is advantageous to the sequence as it protects the end from phosphatases and nucleases.
